Does Demon WP kill German roaches on contact?
I have been spraying them directly I had this mixed with Gentrol and it didn't kill them.
Demon WP is labeled to kill certain pests on contact, as well as leaving a residual. We would recommend giving the product some time to work properly. Please let us know if you have any additional questions.
