Did you ever wonder how pests like rodents, termites, spiders, ants, and biting insects manage to set up residence in your house before your very eyes? Some of them
get inside the same way you do – through the front door, while others enter your home by hitching a ride on things you bring from the outside, such as boxes, lumber, or plants. For a great number of pests, however, the most common entry routes are cracks and crevices leading up to the crawl space.
The crawlspace is the underside of your home, an area built between the ground level and the bottom of the house, creating a permanent foundation and used in place of a basement. (Many buildings, especially commercial establishments, have a crawl space between some of the walls.) Its primary purpose is to facilitate air circulation through the structure and allow easy access to plumbing and electrical systems.
