Why is Diatomaceous Earth Not Killing Fleas?

If you’ve tried using diatomaceous earth for flea control and it has not eliminated fleas, it is important to know why it doesn’t work. The first reason is that it is ineffective when wet or mixed with water. Therefore, it is best to apply it when it is dry. This also prevents it from drying out the skin of your pet.

Diatomaceous earth is made up of silica and cuts the exoskeleton of pests. This results in a reduction in their water content, which is important for survival. Because diatomaceous earth is made up of algae with siliceous shells, the particles are too small to affect humans.

However, diatomaceous earth works best in combination with vacuuming. This is because the diatomaceous earth has to be reapplied every time you vacuum the carpet. This can be time-consuming and inefficient. Besides vacuuming, diatomaceous earth is also great for dusting furniture and baseboards, as fleas often hide in these areas.

If you want to try diatomaceous earth for flea control, it is best to buy the food-grade kind. You can buy it from Amazon or Home Depot. Both are reputable and affordable. However, make sure to check the concentration before purchasing. The product should be at least 99% pure.
