Ron from Modesto, Ca writes
Has a resistance developed? Please recommend a different insecticide. Problem appears to be coming from the neighbors because it is always at the perimeter of the property, none in the house, but it may be approaching.
We recommend rotating between insecticides at least once a year to prevent resistance issues. Even though Suspend SC is an effective product, after 4 years of continuous use, it is possible that resistance has been developed. There is a variety of products you can rotate to, Temprid SC, Suspend Polyzone, Talstar P, and Phantom Termiticide/Insecticide, just to name a few.
