Diatomaceous Earth is also known as diatomite or kieselgur. Despite the name, it isn’t “earth” at all. In fact, it’s the fossilized remains of a certain type of algae.
It comes packaged as a fine white powder. To use it, you put the powder into a duster tool and you spray any surfaces where the roaches are likely to walk.
When the bugs come into contact with the diatomaceous earth, the powder pulls essential lipids from their exoskeletons. This leads the bugs to dehydrate and, eventually, to die. They only need to touch the powder once for it to do its job.
You can find diatomite and a duster tool in most hardware stores or some supermarkets. Alternatively, you can order them both from Amazon to have it delivered.
- Also effective against bed bugs, fleas, slugs, flies and carpet beetles.
- Easy to use.
- For it to be effective the dust has to stay in place. Having a thin layer of dust all around the house can be inconvenient.
- Diatomaceous earth may be a risk to children or pets. You must be mindful of which areas you dust, taking care to avoid areas where your kids or pets play.
- DO NOT USE POOL GRADE DIATOMACEOUS EARTH. It is treated with chemicals, and is dangerous to humans. Use only natural diatomaceous earth.
- You have to pick up the roach carcasses.
