We had a hive of carpenter bees living under our back porch and they buzzed people going in & out the back door, this is the only product that has taken care of it. It was a dangerous situation, we have allergic family members. It was pricey but well worth it! It was easy to dispense and within a couple of days there was no sign of these bees.
Would highly recommend for springtails and other tiny rascal critters trying to get in and live rent free. I’ve used it inside and outside and what a difference. If you are looking for something effective and continuous, this is it.
The product worked very well. The carpenter bees in my deck have been eliminated. They were burrowing into the underside of my deck railings. With the assist of the duster bulb and application tube the dust was very effective at eliminating the pests. Since I applied the product only 3 weeks ago I don't know how long the treatment will last. However, considering the small amount of product I had to use and the one pound quantity of the container I should have enough product for at least several seasons.
