Diatomaceous Earth: The Natural Roach Killer

Roaches are commonplace in the arid climates of the American Southwest; they are also attracted to food which has not been stored properly. While roaches build up resistance to chemical treatments and fumigation costs remain high, diatomaceous earth is an organic, low cost, roach control that is safe to use around your children and pets. Not only will it rid your home of cockroaches, but it continues to work long after chemical solutions have worn away and roaches won't build up a resistance to the effects of diatomaceous earth.

Read the following steps on how to apply diatomaceous earth to your home maximize its effects.

Step 1:

Give your home a thorough cleaning. Maintaining excellent sanitation practices is usually the best defense against cockroaches. As you clean your home, look for cockroaches and mark the places they congregate with a post-it note. Use a flashlight for dark places where roaches might be hiding.

Step 2:

Vacuum thoroughly; be detail-oriented and be sure to move furniture and appliances around. To keep them from returning, it's effective to clean places where food may have dropped.

Step 3:

Dry up any damp areas to prepare for the DE application. To prevent more cockroaches, seal up any cracks that could be under sinks, in the bathroom, near baseboards, or around poorly sealed doors. Any kind of entrance for a cockroach needs to be sealed up. If there are any leaks they need to be taken care of; you can do this with caulk or sealant.

Step 4:

Apply anywhere that cockroaches have been. Dust lightly, since cockroaches won't step on the DE if the dusting is too heavy. Apply the DE anywhere cockroaches can hide, enter your home, and where food is commonly dropped. Don't apply the DE to any area that is consistently damp or wet.

Specifically, use an applicator such as the JT Eaton Duster to spray behind switch and outlet faceplates.

Step 5:

Apply DE around your house along the foundation. If you live in a dry climate you can use one of our wet application methods for your home's exterior. If you live in a damp climate try using our dry applicators like these. Apply DE near any cracks or entrances and along door and window sills.

Step 6:

If you have a crawl space that is not used for storage, treat this area as well. Take 3 lbs of DE and pile it near the entrance to your crawlspace. Using a leaf blower, aim at the pile of DE and turn it on. This should create a large cloud of DE beneath your house. If the crawlspace was not covered repeat the process.

Repeat as Needed

Reapply diatomaceous earth around your home as a preventative measure or after heavy rain, and reapply inside your home if the issue persists.
