Symptoms of Bites from Non-Poisonous Spiders

Spider bites can be classified into two main types, namely the non-poisonous and the poisonous bites. Commonly, the symptoms of a non-poisonous bite include pain, irritation and local redness. When left untreated, this type of bite can heal even without treatment within a period of 7 to 10 days. In rare cases, allergic reaction can develop. However, this reaction may arise from the skin’s contact with the spider rather than the bite itself.

Symptoms of Black Widow Spider Bites

One of the highly poisonous spiders is the black widow. Although some victims may not feel or realize the bite right away, it is comparable to a pinprick. It is also possible to see double fang marks on the bitten area. The common symptoms of this specific kind of bite include redness, swelling and pain. Victims of this bite can also feel a burning sensation in the bitten area.

Symptoms of Brown Recluse Spider Bites

Aside from the black widow, the brown recluse is another type of spider known for its poisonous bite. After being bitten, the victim can feel a mild stinging sensation. It will then be followed by severe pain and local redness. Within eight hours, the victim can experience severe pain, although it is quite possible for it to set in within a few hours more. This kind of bite is usually surrounded by a purple or blue area, which will be surrounded by a whitish circle and a bigger reddish outer circle thereafter. It has a pattern comparable to that of a bull’s eye. Later on, this may develop into a blister filled with fluids. Expect to find a deep ulcer in the bitten area, which is more likely to turn black.

Symptoms of Bites from Spiders with Medically Significant Venom

One of the known spiders with medically significant venom is the Brazilian wandering spider. When bitten by this particular type of spider, the nitric oxide levels of the victim are more likely to increase. Because of this, involuntary erection is possible, an experience which is described as long lasting and very painful.
