There is no valid reason to use both Ultracide and Permethrin in the same areas. Only one is needed when treating inside and the Ultracide already contains an IGR and residual killer as well so another is not needed on top. Applying more product can make an area repellent and insects will avoid it so neither do the job of killing. We have a guide that can help explain the treatment which includes non chemical steps as well.
