I have a plastic trash bag that I use marinate my outdoor clothes in. I put the clothes in with the mothballs, shake it up a let it sit for days. And I still have to spray Off in armpits, behind knees, around waistline and crotch areas.

It is the only way I can keep the chiggers off when I am working in wooded areas or weeds. Even tall grass is a chigger hazard.

And those critters are extra powerful here. A bite can last for over two weeks.


Diatomite is also used as an insecticide, due to its physico-sorptive properties. The fine powder absorbs lipids from the waxy outer layer of insects' exoskeletons, causing them to dehydrate . Arthropods die as a result of the water pressure deficiency, based on Fick's law of diffusion. This also works against gastropods and is commonly employed in gardening to defeat slugs. However, since slugs inhabit humid environments, efficacy is very low. It is sometimes mixed with an attractant or other additives to increase its effectiveness. Medical-grade diatomite is sometimes used to de-worm both animals and humans. It is most commonly used in lieu of boric acid, and can be used to help control and eventually eliminate a cockroach infestation. This material has wide application for insect control in grain storage. It has also been used to control bedbug infestations.
