Cockroaches are nasty pests that can infect your home with bacteria, viruses, potentially deadly pathogens, and allergens. They’re also notoriously hard to kill. When you’re dealing with cockroaches, you need to use an insect killer that’s been proven effective against them. But what are the best choices?
Cockroach killing powders are often more easily controlled than sprays. They also don’t leave behind a sticky chemical residue. The most commonly used cockroach killer in powder form is boric acid, but there are other powdered insecticides that can also work.
