Roaches need water, so they’ll go to great lengths to get it. Partially fill a jar with water and place it where you’ve seen frequent roaches. They’ll climb in for the water and won’t be able to get back out. You can also make a great “soda bottle trap” based on the same principle. Try putting coffee grounds in with the water; the roaches are attracted to coffee.
A bad infestation is a health hazard, and at some point you may need to use a chemical bug spray or insecticide bomb, or even call in the professionals. But try these natural home remedies first; they’re better for your family, your pets and the environment.
