This is great. You've made it easier to know if we have bed bugs now. And it's a good thing we don't use insecticide to kill bed bugs anyway. You could use diatomaceous earth, but the most effective way of getting rid of them is to have a professional kill them with steam. Your wishes are a service to humankind.
