Heat and diatomaceous earth kills bed bugs. The insects can't survive in temperatures above 120 degrees Fahrenheit. It is also best to wash all clothing and sheets that are possibly infested with bed bugs and dry them in the dryer as the dryer heat kills the bugs.
Sprinkling diatomaceous earth in the areas of the home where bedbugs may be present also gets rid of the pests. The bugs become dehydrated after consuming the substance. This remedy only works with food-grade diatomaceous earth. The pool-grade version of the substance is not to be used indoors. If washing sheets and clothing and using diatomaceous earth don't rid the home completely of bedbugs, a professional exterminator may be able to remedy the problem.
