Many species of spiders are common household pests in the Rio Grande Valley. Certain common household spiders spin webs over lamps, in corners and in basements. This creates an unsightly mess but causes no real harm. Remember that every “cobweb” was made by a spider.

Although all spiders use venom when they bite and kill their prey, the black widow and the brown recluse spiders are the only spiders in North America dangerous to humans. Even though their is little danger of complications from spider bites, be advised that all spider bite victims should take the spider with them when consulting their physician.

The Common house spider, sometimes called the American house spider, is an extremely common spider.

There are several species sharing many common features. They build their tangled web in secluded locations, which can also house eggs contained in one or more spherical sacs.

Their behavior on webs is quiet and efficient. They are generally dull in appearance, with patterns consisting of brown shades for coloration. Their average body size is a quarter-inch long. These traits combined allow the spiders to blend into the background and escape noticeThese spiders are not aggressive. They are not known to bite people frequently, nor is their venom known to be dangerous to human beings. When removed from their webs their poor vision renders them helpless.

Their only concern seems to be to find and return to their own web or build another one. They do not wander around inside houses except to find a secure place to build a web. Some people tend to fear all spiders, but since these spiders in particular are harmless and their diet consists of pests such as flies and mosquito, tolerating their presence in homes is beneficial.
