General Facts

Why do I have house spiders?

The common house spider, also known as the American house spider, can be found outside around windows and upper eaves especially near light sources which attract prey. Inside, they are most likely to be found in dark, secluded and humid areas of homes, garages and barns where insects and other food sources can be found in abundance. In addition to feeding on cockroaches and other insects, house spiders cannibalize other spiders that live in close proximity.

How worried should I be about house spiders?

House spiders are acknowledged as a pest due to their unkempt cobwebs and the alarming nature of their presence to anyone with arachnophobia. While house spiders usually only bite when startled, their bites can cause a red mark, with irritation for a number of hours. Notably, an average house spider may live for about a year and produce thousands of offspring during their lifespan, so infestations may spiral out of control if left unchecked. If a house spider infestation takes over your home, contact a professional pest control service to have them eradicated.
