Questions & Answers

4 Customer Questions

How do you use this? I don’t see instructions? I need to use it in a bees nest in an open crevice behind my concrete front steps.

Does this product work on carpet beetles and their larvae?

Answer by Chewy • Nov 05, 2024
This dust is great to use for adult carpet beetles, but for eggs and larvae, a separate insect growth regulator would be recommended.

Does it work on cluster flies?

Answer by Chewy • Aug 26, 2024
This product label does not list cluster flies on the label. This brand has designed a liquid concentrate version of this product that includes cluster flies, which can be purchased on our site separately.

Is this safe to use around cats?

Answer by Chewy • Jul 27, 2022
This product can be applied around animal quarters, but not for use directly on animals. It is recommend to vacuum any treated areas in which pets may come into direct contact with this dust.

Great Deal

Found this while searching for a pesticide to kill wasps. This is the same thing as Delta Dust but for half the price!
