Being the third largest spider family, there are over 2800 species in the Orb Weaver Spider Family.
Orb Weavers with their small fangs may be reluctant to bite. But when they do you can expect pain with numbness and swelling. Also be prepared to feel nauseous and dizzy.

The Black and Yellow Garden Spider are most visible in the summertime and commonly found in garden areas, parks and woodlands making their webs about knee height off the ground in sunny areas. The female garden spider often eats the male after mating. If she feels threatened in her web she will deliver her bite that will cause mild swelling and the pain of a bee’s sting.
There are two reasons to be wary of the Tarantula, its barbed fangs that can deliver the pain of a wasp sting and its barbed, venomous abdominal hairs! When the Tarantula feels threatened it uses its legs to cast hairs in its victim’s face. These hairs can cause skin rashes to swelling or even worse, breathing problems!

Recluse Spider is the most venomous of any spider! Fortunately it is very shy and thought not likely bite people which is a great thing as no antivenom exists for this spider’s bite and it is likely to produce a fatality!!!
