I bought delta dust last year for wasps in my eves. it seems that every other week i was dusting over and over again. my eves were white and still they came back. this year I'm gonna try tempo 1% dust. see how it works when it gets here
I use to have a issue with these bug in the upstairs bedroom.... I was able to get a grip of these bugs by using the spray's in the can. But now these little monsters just walk on the couchf like I put down some baking soda. I used this product as directed.... No such luck... Now I just have some dust in my garage colleting DUST!...
I've previously had great success with Drione dust for clearing wasp nests. This time I tried ordering Delta Dust since it's supposed to be water / rain resistant. When applied to wasp nests, it does seem to irritate them in some way (you can see them rubbing like they're trying to clean it off of themselves), but ultimately it does not kill most of them. When I check the nests the next day, the wasps are still there. I switched back to the Drione Dust, and once again the nests are completely clear within a couple hours of application.
I had wasps nesting in my vinyl siding. I dusted them twice a day at the entrance and around the entrance area, for a full week. I used half if the one pound bottle and the bellows type applicator.
At the peak there were about 15 wasps per minute going into my siding. After a week there were 5 to 8 per minute. I finally used the foaming spray for another two days and then I re'calked the siding. I was a little disappointed.
