Hobo Spiders

 

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.

Black Widow Spiders

Black Widows get the name because of the myth that females eat the male after mating. The fact is that this is very rare. Females are about ½ inch long with a red “hour glass” design on the abdomen. They are shiny black in color. Males are not a danger to humans as they do not bite. Black widows feed on other spiders and insects. Venom can be fatal but mostly in children. Widows try to avoid high traffic areas but will attack if guarding the nest or if they feel threatened. In Iowa, widows are rarely found unless brought in from other states.

Control of spiders is obtained not only through pest control but also by keeping homes clean of clutter and harbor areas. Cleaning up spider webs and food sources will help keep numbers down. Pest control will only help keep numbers down, not eliminate every spider.
