Most of us have been there — an innocent frolic outside with our canine companion leads to a swollen face and hives. Just like their human counterparts, dogs are susceptible to insect and animal bites and stings. These are the ones with cause for concern.

These are extremely common in the spring and summer when insects are the most active. Some dogs will suffer absolutely no ill effects other than mild redness, swelling and discomfort at the site of a sting (much like humans). And, like humans, some dogs develop hives, facial swelling and welts. These can be managed at home with doses of diphenhydramine (brand name Benadryl). First consult your veterinarian on appropriate dosing.

In severe cases, anaphylaxis can develop. A canine having an anaphylactic reaction will begin to:

copiously vomit

have diarrhea

may collapse

Take your dog immediately to emergency care. Your dog will be treated with epinephrine, IV fluids and other supportive care measures. The veterinarian may also recommend carrying an EpiPen for future reactions.

Spider bites on dogs

The two most common venomous spiders in the United States are the widows (Latrodectus sp.) and recluses (Loxosceles sp.). These spiders are timid and tend to live in dark, dry places. This is good for our animal friends, as they don’t come into contact as frequently. It is rare to know for certain that your dog was bitten by a spider, as these species are small and often in places where curious noses can reach but humans do not see.

Widows can be lethal. Dogs are more resistant to the venom than cats, but a small dog could be in trouble. The symptoms are surprising. It can take 8 hours for signs to develop. They include:

marked pain

muscle cramps

diarrhea and vomiting

agitation and vocalizing

facial tremors

a rigid abdomen

Unlike recluse spiders, the wound itself often has no noticeable signs other than mild redness and swelling.

An antivenin does exist, but it is not routinely carried in veterinary clinics. It is costly, and it’s rare to confirm an actual bite. The good news is that the majority of dogs will survive a bite without antivenin. Further, some entomologists estimate that 15 percent of bites are “dry” — meaning that no venom is injected. If you suspect a widow bite, seek veterinary care.

Recluse bites are different and often cause significant localized tissue damage (necrosis). The bite site might go through the following stages:

a small blister shows

the blister turns black

the tissue peels away

Systemic signs are uncommon. Oftentimes, wound care is needed over several days, as well as pain management and antibiotics. These bites are rarely fatal.

Snake bites on dogs

There are about 20 venomous snakes in the United States including rattlesnakes and copperheads. Which your dog could be exposed to depends on where you live. The severity of the bite depends on many different factors including how much venom was injected and how many bites occurred. Most emergency veterinary clinics stock antivenin appropriate for the snakes in their areas.

There are many “old school” remedies that simply do not work. Do not apply a tourniquet or ice the leg. Avoid over-the-counter pain medications. Keep calm and drive to the nearest emergency veterinary clinic.

All snake bites should be evaluated by a veterinarian. In some cases, “dry” bites do occur (no venom injected) and usually pain management is sufficient. In other cases, more aggressive measures such as IV fluids, antivenin, pain relief and close monitoring are needed. Some snake bites cause localized damage while others cause systemic effects like clotting abnormalities and seizures.

Scorpions

Only one scorpion species in the United States is thought to cause signs of systemic envenomation: the bark scorpion. Found almost exclusively in Arizona, it hides under tree bark. Symptoms are generally neurologic:

rhythmic jerking

flicking of the eyes

marked pain both at the site and referred (pain felt elsewhere).

There is no specific antidote in dogs. Care is supportive, and death is very rare. As with any envenomation, do not panic if you suspect your dog has been stung. Seek veterinary evaluation.

Quais aranhas caseiras devemos ficar preocupados (e quais são inofensivas)

É muito comum encontrarmos aranhas em ambientes domésticos como residências, chácaras e sítios. Mas ao contrário do que muita gente imagina, as espécies domésticas, popularmente conhecidas como aranhas caseiras, são animais extremamente importantes para o controle de insetos transmissores de doenças.

São mais de 40 mil espécies existentes no mundo, 12 mil delas existentes no Brasil, sendo 7 comumente encontradas em ambientes domésticos.

Por esse motivo, fizemos uma lista para você conhecê-las um pouco mais, quais apresentam riscos, e como proceder ao dar de cara com uma delas em sua casa. Acompanhe conosco!

Aranhas caseiras que NÃO apresentam risco vital

1. Aranha de Pernas Longas (pholcus phalangioides)

Cultura Mix

Com certeza você já encontrou essa espécie em seu banheiro ou no quarto. A aranha de pernas longas, ou pernada, como nos informa o biólogo Lucas Leandro, do Projeto Biologando, é fácil de ser encontrada por suas pernas chamativas. Adoram ficar escondidas em sua teia, muitas vezes atrás de vasos sanitários.

A boa notícia é que além de sua toxina não atingir seres humanos, elas se alimentam de outras aranhas (que podem apresentar risco para humanos) e evitam ao máximo o contato com pessoas. Até que não é tão ruim tê-la em casa, né?!

2. Aranhas Saltadoras ou papa-moscas (salticidae)

Biofaces

Essas espécies são comumente encontradas nas paredes externas das casas. Com sua ótima visão devido à seus 8 olhos — incluindo na parte traseira de sua cabeça — são capazes de rastrear a presa a uma distância maior que as outras aranhas, além de conseguirem enxergar radiação UVA e UVB, impossível para humanos.

Segundo o biólogo Juninho, elas não possuem músculos em suas pernas, por isso utilizam pressão hidráulica para saltar em sua refeição, podendo saltar 20 vezes sua altura. Essa espécie não carrega toxina ativa em seres humanos.

3. Aranha Vermelha Comum (nesticodes rufipes)

Cultura Mix

De acordo com o biólogo Vanderlei Lopes Mori Junior, o Juninho do canal A vida como um biólogo, por serem muito parecidas, as aranhas vermelha são muito confundidas com as aranhas marrom.

“As aranhas vermelhas, ou viúva vermelha, são as espécies mais fáceis de encontrar em residências. Elas pertence a família de aranhas theridiidae, que inclui a famosa viúva negra (Latrodectus)”.

Entretanto, diferente de sua parente, possuem uma toxina extremamente fraca, incapaz de causar danos a seres humanos, por isso, não apresenta riscos.

4. Aranha de Jardim (lycosidae)

Bugguide

Também é conhecida como aranha lobo, por caçar suas presas de forma direta, perseguindo-as, sem emboscadas. Tem um desenho semelhante a uma seta na parte superior de seu abdômen e muitas vezes são avistadas em jardins. carregando centenas de filhotes em seu corpo. Juninho nos alerta à evitá-las:

“Quando mortas, podem ser confundidas com a aranha armadeira, mas sua toxina não é tão forte quanto. Mesmo assim, quando em contato com o ser humano, sua toxina pode causar irritação no local da picada, dor e queimação”. 

5. Aranha Caranguejeira (theraphsidae)

Insetologia

As caranguejeiras são as maiores espécies conhecidas, podendo chegar até 28cm de envergadura de pernas. Também podem ser consideradas aranhas caseiras, pois comumente aparecem em residências e causam medo por seu tamanho.

Contudo, o maior problema dessa espécie está em suas cerdas (ou pelos) urticantes que cobrem todo seu corpo. Quando ameaçada, a caranguejeira esfrega suas patas no abdômen liberando as cerdas no ar, e quando em contato com mucosas, tais cerdas causam grande irritação.

Conforme Juninho, no Brasil não há espécie de caranguejeira com toxina capaz de matar um ser humano, mas a mecânica de sua picada, é extremamente dolorida.

Aranhas caseiras que apresentam risco vital

6. Aranha Marrom (loxosceles sp)

GPA Brasil

As aranhas marrom são pequenas e gostam de lugares escuros, quentes e secos. Em ambiente externo, vivem embaixo de cascas de árvores, folhas secas, telhas e tijolos empilhados, muros velhos, e outros. Dentro de casa, costumam ficar atrás de quadros, caixas de papelão, em sapatos dentro de armários, e locais que não sejam muito remexidos.

Apesar de não ser agressiva, essa espécie fere o indivíduo quando se sente ameaçada. Sua picada causa intenso processo inflamatório no local, além de hemorragia e necrose.

É preciso atenção para evitar contato com essa aranha, pois muitas vezes o indivíduo não percebe sua presença, e nem mesmo sente sua picada.

Evolução da picada da aranha marrom

7. Aranha Armadeira (phoneutria sp)

Mimoso in foco

A aranha armadeira além de ser grande, é considerada uma das mais tóxicas do mundo e também uma das mais agressivas. Quando ameaçada, levanta as patas dianteiras para defesa, podendo saltar em direção a ameaça.

Segundo o biólogo Lucas, a armadeira é uma caçadora admirável e extremamente perigosa para o ser humano.

“O veneno que ela possui tem ação neurotóxica e cardiotóxica. A neurotóxica ocorre nos canais de sódio, provocando a despolarização nas terminações nervosas, sensitivas, motoras e sistema nervoso autônomo, induzindo-o a liberar neurotransmissores. Já sua ação cardiotóxica, interfere na atividade contrátil do músculo cardíaco, na ativação de fibras sensoriais e também no esvaziamento gástrico.” 

Essa espécie é encontrada escondida em roupas e sapatos. Seu veneno pode causar priapismo (ereção involuntária do pênis, sem excitação sexual) e seu veneno pode ser mortal para crianças e idosos.

O que fazer em caso de contato com alguma das aranhas perigosas

Juninho nos orienta o que fazer em caso de realizar contato com alguma das espécies que apresentam riscos.

“Primeiramente, ligue para um órgão responsável de sua cidade (centro de vigilância epidemiológica) para que eles retirem o animal do local. Porém, se não houverem pessoas autorizadas em sua cidade, com todo cuidado pegue uma vassoura (ou algo mais engenhoso) e conduza o animal para fora da residência.”

O biólogo ainda acrescenta que em caso de acidentes com qualquer espécie, o indicado é procurar o hospital mais próximo o quanto antes, pois mesmo as de toxinas mais fracas, podem causar reações alérgicas.

Como evitar o risco de acidentes com aranhas em casa

A fim de impedir o aparecimento de algumas dessas espécies e evitar o risco de acidentes, algumas medidas podem ser tomadas:

Mantenha o jardim, quintal e casa sempre limpos;

Limpe e mude de lugar com certa regularidade móveis e objetos em casa;

Verifique sempre o interior de roupas e sapatos antes de vesti-los;

Mantenha armários e gavetas sempre fechados;

Vede buracos em paredes, portas, janelas, forros e assoalhos;

Não acumule folhas secas, materiais de construção ou qualquer tipo de entulho;

Quando realizar trabalhos rurais ou de jardinagem, utilize luvas;

Coloque panos embaixo de portas;

Combata a proliferação de insetos (fonte de alimente das aranhas);

Some snake bites cause localized damage while others cause systemic effects like clotting abnormalities and seizures.

Only one scorpion species in the United States is thought to cause signs of systemic envenomation: the bark scorpion. Found almost exclusively in Arizona, it hides under tree bark. Symptoms are generally neurologic:

rhythmic jerking

flicking of the eyes

marked pain both at the site and referred (pain felt elsewhere).

There is no specific antidote in dogs. Care is supportive, and death is very rare. As with any envenomation, do not panic if you suspect your dog has been stung. Seek veterinary evaluation.

Most of us have been there — an innocent frolic outside with our canine companion leads to a swollen face and hives. Just like their human counterparts, dogs are susceptible to insect and animal bites and stings. These are the ones with cause for concern.

These are extremely common in the spring and summer when insects are the most active. Some dogs will suffer absolutely no ill effects other than mild redness, swelling and discomfort at the site of a sting (much like humans). And, like humans, some dogs develop hives, facial swelling and welts. These can be managed at home with doses of diphenhydramine (brand name Benadryl). First consult your veterinarian on appropriate dosing.

In severe cases, anaphylaxis can develop. A canine having an anaphylactic reaction will begin to:

copiously vomit

have diarrhea

may collapse

Take your dog immediately to emergency care. Your dog will be treated with epinephrine, IV fluids and other supportive care measures. The veterinarian may also recommend carrying an EpiPen for future reactions.

Spider bites on dogs

The two most common venomous spiders in the United States are the widows (Latrodectus sp.) and recluses (Loxosceles sp.). These spiders are timid and tend to live in dark, dry places. This is good for our animal friends, as they don’t come into contact as frequently. It is rare to know for certain that your dog was bitten by a spider, as these species are small and often in places where curious noses can reach but humans do not see.

Widows can be lethal. Dogs are more resistant to the venom than cats, but a small dog could be in trouble. The symptoms are surprising. It can take 8 hours for signs to develop. They include:

marked pain

muscle cramps

diarrhea and vomiting

agitation and vocalizing

facial tremors

a rigid abdomen

Unlike recluse spiders, the wound itself often has no noticeable signs other than mild redness and swelling.

An antivenin does exist, but it is not routinely carried in veterinary clinics. It is costly, and it’s rare to confirm an actual bite. The good news is that the majority of dogs will survive a bite without antivenin. Further, some entomologists estimate that 15 percent of bites are “dry” — meaning that no venom is injected. If you suspect a widow bite, seek veterinary care.

Recluse bites are different and often cause significant localized tissue damage (necrosis). The bite site might go through the following stages:

a small blister shows

the blister turns black

the tissue peels away

Systemic signs are uncommon. Oftentimes, wound care is needed over several days, as well as pain management and antibiotics. These bites are rarely fatal.

Snake bites on dogs

There are about 20 venomous snakes in the United States including rattlesnakes and copperheads. Which your dog could be exposed to depends on where you live. The severity of the bite depends on many different factors including how much venom was injected and how many bites occurred. Most emergency veterinary clinics stock antivenin appropriate for the snakes in their areas.

There are many “old school” remedies that simply do not work. Do not apply a tourniquet or ice the leg. Avoid over-the-counter pain medications. Keep calm and drive to the nearest emergency veterinary clinic.

#BiGFicTioN Latrodectus Geometricus, a aranha Viúva Marron, segundo o site Insectologia.com.br: http://www.insetologia.com.br/p/arachnida-aranhas.html: "Aranhas Viúva Latrodectus sp. Aranhas viúvas têm veneno potente de efeito neurotóxico. Apesar da espécie L. geometricus ser comum em ambientes modificados pelo homem, não causa muitos acidentes. O Brasil não fabrica soro para Latrodectus spp. Teridiídeos são aranhas tímidas, acidentes normalmente acontecem se a aranha se encontrar em uma peça do vestuário." #BiGFicTioN #AlienAranha #BrownWidow and your beautiful hourglass

Quais aranhas caseiras devemos ficar preocupados (e quais são inofensivas)

É muito comum encontrarmos aranhas em ambientes domésticos como residências, chácaras e sítios. Mas ao contrário do que muita gente imagina, as espécies domésticas, popularmente conhecidas como aranhas caseiras, são animais extremamente importantes para o controle de insetos transmissores de doenças.

São mais de 40 mil espécies existentes no mundo, 12 mil delas existentes no Brasil, sendo 7 comumente encontradas em ambientes domésticos.

Por esse motivo, fizemos uma lista para você conhecê-las um pouco mais, quais apresentam riscos, e como proceder ao dar de cara com uma delas em sua casa. Acompanhe conosco!

Aranhas caseiras que NÃO apresentam risco vital

1. Aranha de Pernas Longas (pholcus phalangioides)

Cultura Mix

Com certeza você já encontrou essa espécie em seu banheiro ou no quarto. A aranha de pernas longas, ou pernada, como nos informa o biólogo Lucas Leandro, do Projeto Biologando, é fácil de ser encontrada por suas pernas chamativas. Adoram ficar escondidas em sua teia, muitas vezes atrás de vasos sanitários.

A boa notícia é que além de sua toxina não atingir seres humanos, elas se alimentam de outras aranhas (que podem apresentar risco para humanos) e evitam ao máximo o contato com pessoas. Até que não é tão ruim tê-la em casa, né?!

2. Aranhas Saltadoras ou papa-moscas (salticidae)

Biofaces

Essas espécies são comumente encontradas nas paredes externas das casas. Com sua ótima visão devido à seus 8 olhos — incluindo na parte traseira de sua cabeça — são capazes de rastrear a presa a uma distância maior que as outras aranhas, além de conseguirem enxergar radiação UVA e UVB, impossível para humanos.

Segundo o biólogo Juninho, elas não possuem músculos em suas pernas, por isso utilizam pressão hidráulica para saltar em sua refeição, podendo saltar 20 vezes sua altura. Essa espécie não carrega toxina ativa em seres humanos.

3. Aranha Vermelha Comum (nesticodes rufipes)

Cultura Mix

De acordo com o biólogo Vanderlei Lopes Mori Junior, o Juninho do canal A vida como um biólogo, por serem muito parecidas, as aranhas vermelha são muito confundidas com as aranhas marrom.

“As aranhas vermelhas, ou viúva vermelha, são as espécies mais fáceis de encontrar em residências. Elas pertence a família de aranhas theridiidae, que inclui a famosa viúva negra (Latrodectus)”.

Entretanto, diferente de sua parente, possuem uma toxina extremamente fraca, incapaz de causar danos a seres humanos, por isso, não apresenta riscos.

4. Aranha de Jardim (lycosidae)

Bugguide

Também é conhecida como aranha lobo, por caçar suas presas de forma direta, perseguindo-as, sem emboscadas. Tem um desenho semelhante a uma seta na parte superior de seu abdômen e muitas vezes são avistadas em jardins. carregando centenas de filhotes em seu corpo. Juninho nos alerta à evitá-las:

“Quando mortas, podem ser confundidas com a aranha armadeira, mas sua toxina não é tão forte quanto. Mesmo assim, quando em contato com o ser humano, sua toxina pode causar irritação no local da picada, dor e queimação”. 

5. Aranha Caranguejeira (theraphsidae)

Insetologia

As caranguejeiras são as maiores espécies conhecidas, podendo chegar até 28cm de envergadura de pernas. Também podem ser consideradas aranhas caseiras, pois comumente aparecem em residências e causam medo por seu tamanho.

Contudo, o maior problema dessa espécie está em suas cerdas (ou pelos) urticantes que cobrem todo seu corpo. Quando ameaçada, a caranguejeira esfrega suas patas no abdômen liberando as cerdas no ar, e quando em contato com mucosas, tais cerdas causam grande irritação.

Conforme Juninho, no Brasil não há espécie de caranguejeira com toxina capaz de matar um ser humano, mas a mecânica de sua picada, é extremamente dolorida.

Aranhas caseiras que apresentam risco vital

6. Aranha Marrom (loxosceles sp)

GPA Brasil

As aranhas marrom são pequenas e gostam de lugares escuros, quentes e secos. Em ambiente externo, vivem embaixo de cascas de árvores, folhas secas, telhas e tijolos empilhados, muros velhos, e outros. Dentro de casa, costumam ficar atrás de quadros, caixas de papelão, em sapatos dentro de armários, e locais que não sejam muito remexidos.

Apesar de não ser agressiva, essa espécie fere o indivíduo quando se sente ameaçada. Sua picada causa intenso processo inflamatório no local, além de hemorragia e necrose.

É preciso atenção para evitar contato com essa aranha, pois muitas vezes o indivíduo não percebe sua presença, e nem mesmo sente sua picada.

7. Aranha Armadeira (phoneutria sp)

Mimoso in foco

A aranha armadeira além de ser grande, é considerada uma das mais tóxicas do mundo e também uma das mais agressivas. Quando ameaçada, levanta as patas dianteiras para defesa, podendo saltar em direção a ameaça.

Segundo o biólogo Lucas, a armadeira é uma caçadora admirável e extremamente perigosa para o ser humano.

“O veneno que ela possui tem ação neurotóxica e cardiotóxica. A neurotóxica ocorre nos canais de sódio, provocando a despolarização nas terminações nervosas, sensitivas, motoras e sistema nervoso autônomo, induzindo-o a liberar neurotransmissores. Já sua ação cardiotóxica, interfere na atividade contrátil do músculo cardíaco, na ativação de fibras sensoriais e também no esvaziamento gástrico.” 

Essa espécie é encontrada escondida em roupas e sapatos. Seu veneno pode causar priapismo (ereção involuntária do pênis, sem excitação sexual) e seu veneno pode ser mortal para crianças e idosos.

O que fazer em caso de contato com alguma das aranhas perigosas

Juninho nos orienta o que fazer em caso de realizar contato com alguma das espécies que apresentam riscos.

“Primeiramente, ligue para um órgão responsável de sua cidade (centro de vigilância epidemiológica) para que eles retirem o animal do local. Porém, se não houverem pessoas autorizadas em sua cidade, com todo cuidado pegue uma vassoura (ou algo mais engenhoso) e conduza o animal para fora da residência.”

O biólogo ainda acrescenta que em caso de acidentes com qualquer espécie, o indicado é procurar o hospital mais próximo o quanto antes, pois mesmo as de toxinas mais fracas, podem causar reações alérgicas.

Como evitar o risco de acidentes com aranhas em casa

A fim de impedir o aparecimento de algumas dessas espécies e evitar o risco de acidentes, algumas medidas podem ser tomadas:

Mantenha o jardim, quintal e casa sempre limpos;

Limpe e mude de lugar com certa regularidade móveis e objetos em casa;

Verifique sempre o interior de roupas e sapatos antes de vesti-los;

Mantenha armários e gavetas sempre fechados;

Vede buracos em paredes, portas, janelas, forros e assoalhos;

Não acumule folhas secas, materiais de construção ou qualquer tipo de entulho;

Quando realizar trabalhos rurais ou de jardinagem, utilize luvas;

Coloque panos embaixo de portas;

Combata a proliferação de insetos (fonte de alimente das aranhas);
