I need to apply dust to my patio. Specifically the limestone tops of counters and sitting walls (about 400 square ft). Does powder spray like a mist that will provide coverage or can I somehow ‘spread it’?

Thank you!

I just purchased Niban FG, Coquer EC for the cave cricket problem I have. I also purchased Drione Dust two years ago for a carpenter bee problem (which I am glad I bought the drione dust, problem solved). My basic question(s) are: Can I also use the drione dust for the cave crickets? Is the Drione Dust as effective as the Deltamethrin Dust? Do you recommend purchasing the Deltamethrin Dust?

Will the Insects killed with dust be harmful to pets that may eat them?

For the last several years, I’ve had a problem with wasp diggers. They are digging holes everywhere and my lawn looks terrible. Will this kill St Augustine grass?

Thank you

Only had to spray once about 6 times into the hole and have not seen them since. Thanks for the product and the easy instructions!!

I am renting a cottage which has a crawl space (all dirt) that I can not get to at all.

I have a recurring problem with crickets and other insects coming up and into my living space.

The good news is that I can get to the spaces to possibly spray and or put some powder down in through the thin space with the proper tools/equipment.

There is a small boiler room where I do notice the insects like to crawl up and into that heated area.

What can I use to get into the crawl space via thin openings between the floor and the crawl space? I will be buying silicone sealer and wire to block of the spaces once treated.

Thank you.

Great stuff! This product got rid of an infestation of cave crickets at a bargain price. Much cheaper than an exterminator!

Hi, I have a springtail infestation. Just wondering if this dust works for those little guys also.

I have bees in a large pot with ivy. These bees look like honey bees with black and yellow stripes on their lower abdomen. When I water the area, I tend to get 5 to 10 flying out, but they are not aggressive as I am usually not more than 3 or 4 feet away and at most I may have had one briefly fly around me then go back toward the nest and not make an effort to sting. I have blurry photos if that would help. I am concerned as I have read that they tend to spread out a lot over time. Any idea what they are, and would putting a large amount of the deltamethrin around the area that they seem to come from get rid of them? Thanks.

After reading the article on this site about springtail control l, I purchased this and have puffed into siding where I’ve seen springtail babies coming out and in my bathroom in the cracks also around perimeter of my back yard to the house. I believe it is effective. And it lasts long.

I’m looking for a really good insecticide for my crawl space. Something that will kill spiders, cockroaches, ants, giant crickets, earwigs, etc. I would prefer a dust so it will get in all the cracks and crevices.

I used this product in combination with exterior granules and liquids, as well as an interior liquid to combat a springtail issue. Saw diminished populations concentrated in bathroom wet wall after dusting through any opening I could without breaking the walls (behind escutcheons and electrical wall plates). The best results came after dusting under the exterior siding. I only dusted along the bottom perimeter of my vinyl siding and wherever there was a seam/overlap in the siding. I also did my best to get into the corner trim and other nooks and crannies where I could stick the duster end into. After doing this, I saw greatly diminished quantity of springtails inside my house (but this is also combined with using outdoor granules and liquids and interior liquid sprays – the dust alone won’t solve the problem). I used almost a full container of dust for my 1200sf house and 500 sf detached garage.

We have a weevil problem and think they may be coming out of the attic which is more of a crawl space. They may also be in the ductwork? House is a ranch style; what size product do you suggest.
Thank You.

A product that actually works! We have been dealing with spider crickets from the basement for years!!! It was getting so bad that they were making their way to the upstairs as we kive in an old 3 story speakeasy house. We’d always find them in our sink, bathtub, stairway you name it. They were out of control. After trying so many things nothing was working and they got worse. I did some research, came across this powder. We hit their den with it, went all along the basement floor edges and corners. The shocking results and truth ,,,,WE HAVEN’T SEEN 1 IN OVER A WEEK!!!!!! Whatever is in this product, them buggers certainly don’t like it and we couldn’t be happier. A little goes a long way and before we run out, we’ll be ordering again. Worth every single penny. ! Thank you!!!!
