Good Product
Used it on carpenter ants entering an access point of the exterior wall, and they disappeared after a few days. When I replaced the rotted board, there were no ants left inside the crevice.
On the other hand, I dusted another area where I saw bees entering under the porch steps (could not see the nest) and the bees are still there.
Overall, I am satisfied with this product.

Yellow jackets in and from vinyl siding
This product did not work to keep yellow jackets from behind vinyl siding, squirted all around area they were entering and directly in and behind vinyl. Some hovered around and some went right back in? right through, on, over the dust and all ended up re entering. Just a side note that I could not see the nest nor could I spray the nest.

DIY RESPONSE: Dust is the slowest form of insecticide and can take a long time to kill the insects. Dusts have their place in a pest management program when you can place the dust in a place where it will stay undisturbed by weather. If you see no improvements call us at 1-800-476-3368. Ken is an expert on yellow jackets, his extension is 7101.

Works fine
Dusted the powder into the entry hole used by the wood boring bees. They never came back.

Not good for Brown Recluse
I am not a review writer normally; but my experience tonight lead me back here. My buying experience was great; but the product is not good for my needed application. I actually caught a mature Brown Recluse tonight in a jar. I covered it with the dust. 3 hours later it was still alive and well. Very disappointed.

DIY RESPONSE: Sorry you're not finding success with D-Fense. Dusts are the slowest acting form of insecticide that you can use. It is very persistent and will eventually kill the spider but it may take a day or two.

Cheaper than Delta
The sales rep told me this is the same stuff as delta dust. I've used delta dust for years with good results. Since this is the same I'm expecting the same results. 4 stars since I havent finished applying it.
