Yes, D-Force HPX can be applied with Gentrol IGR. We would recommend using the Gentrol IGR first and letting it dry. The residual is 4 months with this product so you do not have to use this every time you are spraying for the cigarette beetles. D-Force HPX has a residual of up to 8 weeks. Please let us know if you have any additional questions.
