Cockroach Versus Traps: Tested Pack vs Home Use (Surprising Insight) Deploying the 20-pack of Cockroach Traps in our living space was an experiment in layered defense. We set them in corners, behind appliances, and near potential entry points, noting their longevity as a key benefit. The traps’ design proved surprisingly effective against American and German roaches, with sticky surfaces trapping several insects within days. While we did prefer the commercial-grade strength for our home use, we noticed the traps’ versatility—just as useful in our kitchen as they would be in a cafe. The only surprise? How stealthy these pests are until they’ve been caught. For sustained control, we recommend strategically placing ours every few feet. The 20-pack ensures backup when the first set fills up.
