Bayer Advanced Complete Insect Killer For Soil & Turf is not labeled for Box Elder Bugs. To get rid of box elder bugs, it is recommended to use a pyrethroid-based insecticide, such as Suspend SC or Talstar P. You may want to take a look at our Box Elder Bug Guide for more information.
Bayer Advanced Complete Insect Killer For Soil & Turf can only help with mosquitoes that contact the treated soil but is not the best option. Key with mosquite treatments is applying a liquid residual to the underside of leaves on trees/bushes where the adults lay during the day. Suspend Polyzone is a great product to do this with.
