I need the powder that kills the carpenter bees – it was used once before on my deck by a exterminator. Is this the same powder? The “mother earth” powder?
We’ve got three powders that are commonly used by pest control companies. All three will work well. The main one featured in our CARPENTER BEE CONTROL article is is the DRIONE DUST. It’s mostly silica gel with some pyrethrin and used to be the main powder used overall. But due to supply issues, Drione has been somewhat hard to get and it’s price has jumped up quite a bit. During this time two other dusts have become good substitutes and should perform almost as well.
The first one is PYGANIC DUST. Mostly made of silica gel, Pyganic is very close to Drione in that it’s got pyrethrin too. The one main difference is in the lack of synergists which prevents Pyganic from working as acutely compared to Drione. But overall residual should be similar if not the same and side by side, the average person wouldn’t notice much if any difference between the two.
The second viable option is the MOTHERS EARTH DUST. Comprised of diatoms, this powder is a good desicant but it doesn’t contain any pyrethrin. Without this vital ingredient, Mothers Earth won’t provide a good flush or knockdown compared to both Drione and Pyganic. But will it work? Yes. When applied directly into the bee nests like we discuss in our article and what you probably had done some time ago on your deck, the dust will last a long time if it’s sealed up with our 1/2″ PLUGS. This will keep it active long enough to deal with hatching eggs which are always a risk in these nests.
