House Spiders in Massachusetts
House spiders might not be dangerous, but their messy webs and explosive reproductive rates can quickly turn them into a major household nuisance.
What Makes House Spiders a Problem?
While common house spiders pose no real physical threat to humans—and are not known to bite unless threatened or crushed—they are a significant nuisance pest. The main problem with house spiders lies in their web-building habits and their rapid reproduction rates. A female house spider lays about 250 eggs in a single silken sac, and can produce up to 17 sacs in her lifetime—meaning over 3,700 eggs! These eggs hatch in just 7 to 10 days, allowing populations to grow alarmingly fast.
Furthermore, house spiders build tangled webs by trial and error. If a web doesn't catch any food, the spider will simply abandon it and build a new one somewhere else. Over time, these abandoned webs collect dust and create unsightly, messy cobwebs all over your home.
Where Do House Spiders Hide & Thrive?
House spiders are the most commonly encountered spiders indoors, though they actually have a hard time surviving in modern homes due to low humidity and a lack of insects for food. Because of this, they thrive best in darker, less disturbed structures like garages, sheds, barns, basements, and crawl spaces.
Inside your living spaces, you are most likely to spot them hiding out in upper corners, tucked under furniture, in the angles of window frames, or deep inside closets. Outdoors, they often hang around windows and under eaves, especially near light sources that attract their insect prey.
How Can You Prevent a House Spider Infestation?
Preventing house spiders starts with making your home as inaccessible and unappealing to them as possible. Start by sealing up any cracks and crevices around the outside of your house using a high-quality, silicone-based caulk. Ensure that all your windows and doors have tight-fitting screens with no tears.
If you spot a spider or a web indoors, skip the broom—adult spiders can usually escape the bristles. Instead, use a vacuum to effectively suck up the adult spiders, their webs, and most importantly, any hidden egg sacs. Keeping other insect populations down in general will also remove the food source that attracts these spiders in the first place.
Why Do You Need Professional Help?
While you can vacuum up visible webs and occasional spiders, frequent sightings or excessive webbing indicate a much larger issue that requires professional intervention. Because of their rapid breeding cycle and tendency to hide in hard-to-reach areas, DIY methods often miss the egg sacs hidden deep in crevices, leading to an endless cycle of new spiders.
