How do bugs get into homes and what can you do to stop them? – Bugs, snakes, mice and other unwanted pests get into homes the same way we humans do…They simply walk in. And the number one place they do that is underneath your doors leading to the outside. In most homes, the door thresholds don’t fit very tightly and there is a slight gap between the bottom of the door and the threshold plate. If you get down on your knees and look underneath your doorway leading to the outside, there is a good chance you can see daylight. If you can, you know that roaches, ants, spiders, crickets, scorpions, small snakes and lizards and various other unwanted pests can see the gap also…and they will use it to come and go as they please…just like YOU do! Bottom line…seal up that crack underneath the door with a tight fitting threshold and you will eliminate the number one way bugs get into your home!
