These substances function as fumigants, repellents, and insecticides. Several studies validate that these compounds have attributes that boxelder bugs find intolerable.
To use sage against boxelder bugs, plant sage in your garden around the perimeter of your home, creating a natural barrier that keeps these pests at bay.
Once the mixture cools, spray the areas where the bugs congregate and their potential entry points. Alternatively, place fabric pouches filled with dried sage around your home.
