There are about 30 different kinds of tarantulas in the U.S. Most are found in the southern states. The bite of a tarantula is painful but not dangerous. Some species have the ability to shoot hairs as a defense mechanism the hairs can be irritating. Tarantulas build burrows in the ground and then ambush prey. They will feed on any kind of insect or even small rodents.
In Iowa, these are not a realistic pest to have to deal with. If any are found it would be from a released pet or pet shop. Tarantulas are beneficial spiders in areas where they are found. Adults have been reported to live for two years or more

These spiders are called hobos because they hitch rides with humans and transfer to different areas. They are found all over the western states but the range is spreading rapidly. It is thought that the bite might cause legions but medical research is foggy on this subject.
Adults are 11-14mm in length and are off brown colored. They prefer dark, moist areas that are undisturbed. They are not good climbers so they are mainly found along the ground. Hobo spiders will make nests in cracks and also in the ground. Usually, the holes are surrounded by the silken web which helps catch prey. Hobos feed on other insects and other spiders. Control is the same as other spiders with spray and keeping clutter off the ground around the house. When these spiders invade homes, crack and crevice treatments are necessary. Remove webs and eggs to keep numbers in check.

Cellar/Daddy Longlegs Spiders
There are about 20 different species of daddy longlegs spiders or cellar spiders in the U.S. They are more of a nuisance because of the immense amount of webs they produce. Daddy longlegs have long legs about 2-8mm in length and are off brown colored. They are usually found along basement ceilings and front porches.
Daddy longlegs are harmless to people and feed on other insects and spiders. Pest control can be used to keep numbers down but homeowners can also remove webs and eggs to keep numbers down. They are the most common spider of homeowners in Iowa and many other states.

Brown Recluse Spiders
Brown Recluse spiders are also called fiddle backs. They get the name from their reclusive behavior and fiddle shaped design on their back. Adults are generally about the size of a quarter. They have long legs and hold themselves up high off the ground. Brown recluses are light brown in color. They do not make webs but prefer dark, moist, undisturbed areas like crawlspaces, attics and closets. If provoked, they will bite and it can be painful.
There is no cure for infected areas other than removing skin and areas that are dying. If left alone, infected areas spread all over. Medical attention should be sought if bites are suspected. Outdoors they prefer shingles, unused boxes, woodpiles, or clutter in garages for shelter. Pest control is recommended for houses with these spiders.
