diatomaceous earth. Kills ants...safe for buns.
I have a rather extensive article on the use and safety of the stuff, If I had your email I would send it...too big for here.
Below is a report on Diatomaceous Earth (DE) that I have copied as a service to my readers and is a result of my studies concerning Diatomaceous Earth (DE). I have no permission from the FDA or the USDA to make any claims concerning Diatomaceous Earth (DE). These claims are from the my searches of the internet and from literature I have in my possession. I am using Diatomaceous Earth (DE) and I have seen good results but I haven't used it long enough to prove all of these claims and I can't guarantee you will share the same results. I do have the CFR numbers showing FDA and USDA approval for using Diatomaceous Earth (DE) as a feed additive. I have been studying feeds and feeding for some time now and, about 6 months ago, I started learning all I could about diatomaceous earth. This is a natural pesticide and has no ill effects when used with animals. Be sure to get the food grade diatomaceous earth because it has been approved by the FDA and USDA. (The pool grade and filter grade have not been approved as a feed additive and it may be harmful to use them and they will not accomplish the desired results) This will kill all internal and external parasites, aid in feed conversion, control flies by killing the larvae in manure, control odor, and promote better health and egg laying. This will also kill other insects in your garden, orchard, home, and lawn. It is great for controlling ants. I recently became a dealer for DE because it is all natural and there were no dealers in my area. This kills insects and parasites by cutting their exoskeleton and they dehydrate. It contains no poisons.
Make sure the DE you use meets World Health Organization (WHO) safety standards. WHO cautions that DE with a crystalline silica content over three percent (3%) is dangerous for ingestion by humans or animals. Safe Solutions, Inc. DE has less than 1% free silica. Swimming pool DE ranges from 60% to 70% free silica.
Quote from Steve Tvedten's "The Bug Stops Here":
DIATOMACEOUS EARTH (DE) - Diatomaceous earth is a mineral product mined from the fossilized silica shell remains of unicellular or colonized algae from the class Bacillariaphyceae, better known as diatoms. There are many different companies that sell DE. The Author recommends the product sold by Safe Solutions, Inc. Most registered DE has pyrethrin and pipernoyl butoxide (PBO). Some unregistered (without pyrethrin and PBO) food-grade diatomaceous earth (DE) is safe enough to be eaten, yet will kill most crawling insects. Be sure you have the best quality. Make sure the DE you use meets World Health Organization (WHO) safety standards.
