Jumping Spiders

This spider gets its name from the fact that they can jump to get to their prey. They are small about 4-10 mm. Jumping spiders have large eyes and a “fuzzy” appearance. Some have red on their back which can be mistaken for black widow markings. They are harmless to humans and can be found indoors.

            Jumping spiders do not catch prey in webs but will have small webs for protection and escape. They are unusual from other spiders in that they will be quite active during the day and love warm, sunny days. They can jump up to 20 times their body length. They can be found on cement porches, woodpiles, fences and old wood. Control is obtained through spraying.

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.

Spiders

There are over 35,000 species of spider all over the world. Only about 2-3000 are known in the U.S. Spiders are found wherever there is adequate food, moisture and temperature. Every spider is considered a predator and in the U.S there are only two known types to be dangerous to humans (widows and recluses).

 

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.
