Throughout the fall season we have been experiencing some problems with the number of white grubs that have been living in our soil. These grubs are a huge problem because they can cause a lot of damage if they aren’t taken care of. White grubs usually feed on the roots of produce. If you have these grubs in your lawn, your lawn will show wilting and browning. If you dare, look up a picture on any search engine.

We are going to spread diatomaceous earth (or DE) on our garden to treat the grubs. DE is a nontoxic, organic concoction made of the fossilized remains of tiny one-celled marine animals called diatoms. Chemically, it’s almost pure silicone dioxide. The absorptive properties of DE is what will act on the grub. The powdery DE will absorb the body fluids and dehydrate the grubs.

If you are using DE be careful if you are applying by hand because it may dry your skin. Industrial grade diatomaceous earth, which has larger quantities of a highly crystallized form of silica, should never be inhaled due to possible health risks for the lungs. Breathing in too much food grade diatomaceous earth may irritate the mucus membranes in the nose and mouth and it may dry out your skin. Once the dust settles, it does not pose a threat.

We can’t wait to lay down our DE!
