A big advantage of Crossfire is the ability to use it in many places that cannot be treated with other insecticides, but when mixed with Gentrol, those places-like mattress surfaces-can no longer be treated. Correct?
Crossfire should only be mixed with water. You can mix Gentrol IGR at 1 oz per gallon of water for a crack and crevice application after you have applied the Crossfire and it dried.
