What Kills Bedbugs Instantly?
High temperatures can kill bedbugs instantly. Diatomaceous earth is also lethal to bedbugs because it dehydrates them, causing death relatively quickly. While various pesticides kill bedbugs, they can cause health problems in humans if used incorrectly.
While you can sometimes tackle minor bedbug infestations yourself, you'll need to call the professionals if the infestation gets out of hand. Seeing bedbugs in unusual places, such as window sills or electrical outlets, signifies that you need professional bedbug extermination. You may wish to call an exterminator sooner if the bites are causing major discomfort.
