Re: Use food grade diatomaceous earth to kill ticks, spiders, ants...etc...
Pool grade DE is processed differently. As to it not killing ants or anything else, it will NOT kill adult anything, except bees, it kills in the larvae stage. DE did not work for you because you may have incorrectly used the product. You must either apply it just before a rain or thoroughly wet the ground after dusting so it can soak in. And YES it does work quite well. I have been using it 2-3 times a year for the last 6 years and my SHB problem is nearly gone. I don't use anything else most years. I get mine at the local CO-OP for $40.00 for a 50lb bag. They call it feed grade.
