Can you use defense dust inside of electronic like computer stereo TV xcetera?
Keith W on Dec 29, 2017
BEST ANSWER: No, I would not recommend using in Electronics, if you are trying to control roaches then it would be better to apply a bait or bait stations around those items.


Nuvan pro-strips can be used to treat these items, you will want to place them in a seal-able container and allow to stay for a couple of days.

BEST ANSWER: If they come in contact with D-fense dust then yes it will kill them.
Will this product work on bees? All type of bees or only Carpenter bees? I have a small opening under my shed where they seem to have a nest and hoping to dust inside the hole with the right chemical to kill all bees and make the area uninhabitable.
David on May 11, 2017
BEST ANSWER: D-fense dust when dusted into an opening that is inhabited by Carpenter bees or other bees will kill them. It is not however a contact insecticide and certain types of bees other than Carpenter Bee will be aggressive so common sense and caution should be used.

This powder works wonders on water bugs, I have never got results from other dusts like I did this one. A winner in my book!

We used D-Fense in our restaurant. It works well on keeping the flies and roaches down.
