Diatomaceous earth is a natural and safe insecticide to eliminate bed bugs. Diatomaceous earth powder helps to kill off bed bugs by causing them to dehydrate because it destroys their outer protective membrane. Some people also call it bed bug powder. Because vacuum cleaners may not remove all bed bugs in deep crevices, diatomaceous earth powder is an excellent way to control bed bugs and prevent further infestation.
A study into the use of diatomaceous earth in bed bug eradication found that it is a safe, non-toxic way to rid your home of bed bugs. Even though diatomaceous earth (DE) is slow acting, the study found that this was an advantage. This is because the bed bugs transfer the powder to other bugs and help to distribute the natural insecticide to their habitats. The study found that within 40 days, 80% of all the bed bugs had been killed. Complete eradication was achieved in 12 days.5
To naturally eliminate a bed bug infestation with diatomaceous earth, dust the bed bug powder around all areas where bed bugs may be hiding. Repeat the process every 3 days for 2 weeks to ensure complete removal of all the bed bugs.
Make sure to use food grade diatomaceous earth (here is one example), as it is safe to use around the home and it’s an effective home treatment for killing bed bugs and fleas.
