Control Inside the Home
More than any pesticide or other pest control method, the best way to prevent spiders is to keep the home clean and free of food sources. Spiders are solitary hunters that prefer darkness and prey on other pests. They often take residence in corners or crevices where they are both safe from human danger and more likely to catch unsuspecting pests as they make their way into or around the home.
For prevention, begin by cleaning cluttered areas of the home, especially the garage, attic, closets and bathrooms. Spiders prefer areas where it's cool and dark, so make sure to get areas underneath and behind furniture to prevent spiders from making themselves at home. A vacuum also works well to clean underneath furniture, behind appliances and in inconspicuous areas where spiders lurk.
If you see spider webs in the corner of closets, bedroom walls or door frames, swat the web with a newspaper. Even if the spider isn't present on the web, it's an indicator that they will return or leave it behind for another spider to take up residence.
Spiders are repelled by citrus scents such as lemon, orange and lime, so any time you clean surfaces with a scented cleaner, use one with a citrus odor to act as double duty as a spider repellent. Spray along baseboards, doorways, in bathrooms and kitchen surfaces where spiders heavily frequent.
Of course, there are common pesticides found in stores that work just as well in killing spiders at home. If exposure to pets and children are a concern, consider using pesticides made of natural ingredients that are non-toxic. Some of the most effective pesticides are those that also kill moths, mosquitoes, and flies. This helps eliminate the source of food for spiders, encouraging them to move elsewhere.
Outside, there are many do-it-yourself techniques that can get rid of spiders. One of the best ways to get rid of spiders is to eliminate their food source. This means killing off other pests such as mosquitoes, flies, moths and similar bugs. Pesticides can be applied to the lawn and garden for potential pests that spiders feed on.
Keep outdoor lights turned off to help limit other pests and the food source for spiders. Moths in particular are attracted to porch lights, which is why spider webs are often found covering them.
If you notice egg sacs around the exterior of your home, use a pesticide spray to get rid of the eggs before they hatch. Spiders can lay up to 100 eggs or more each time, which can greatly lead to infestations and reoccurrence of the same problems.
