Spiders are often the sign of a more serious insect infestation in the home. Spiders often hide out in cracks and crevices in well-protected undisturbed areas inside or outside of the home such as; eaves, vaulted ceiling corners, bookcase voids, under patio furniture or play equipment etc.
Spiders eat other insects, so protecting your home from other types of insects and keeping a tidy home can often times be the first line of defense against spiders indoors.
There are only a few species of spiders whose bites pose a threat to humans, the Black Widow and Brown Recluse. Spiders are natural predators and will not bite unless threatened or provoked when unintentionally disturbed. Most of the time, suspected spider bites are often the result of bites from other insects, but nonetheless special precaution should be taken if you suspect you have been bitten.
