Spiders are easy to recognize with eight legs and a round abdomen. They are some of the most feared creatures that we treat and sometimes the most misunderstood. While most spiders only cause swelling and irritation some can lead to more severe health risks. Our most common species of spider in Texas are the black widow and the brown recluse. Both of these species of spiders can be found indoors and outdoors through out the State. Black widow spiders can frequently be found in woodpiles, boxes, outdoor toilets, meter boxes, under eaves, and other undisturbed areas. Brown recluse commonly live in basements and garages of houses and can be found hiding between boards, boxes, and old towels and clothes in dark, undisturbed areas. Neither the black widow nor the brown recluse spiders are aggressive but they will both bite when accidentally trapped, disturbed or threatened.
