The best defense is a good offense when it comes to protecting the outside of your home from pests. Inspect the exterior of your house and patch any cracks or other openings that may have developed over the winter.
Keep ants from becoming unwanted guests in your living room by vacuuming the entry/living room areas thoroughly to get rid of any crumbs, and clean up any sweet, sugary spills which are the number one culprit for attracting ants in this area. Also, try a non-toxic ant repellant such as ant elimination pouches. Try out essential oils and plant fibers, so they are eco-friendly and have no known risks associated with use in the home.
Moths also can consider closets a place to call home, but a 24 hour pest control specialist pouch can keep them at bay. In the bedroom, the non-toxic spiders repellant offers a similar strategy. After vacuuming to remove any existing webs, use the repellant to prevent additional infestations.
