I had a pest control company do my quarterly treatment and they sprayed Bifen on my outside walls where there were caterpillars. After the spraying, I had red trails all over the walls and now have stained the walls. How come this is and does this product do this?
We have never had a report of bleeding caterpillars in the past. We recommend that you contact the pest control company that sprayed your home or the Bifen IT manufacturer Control Solutions for more information. Control Solutions: (281) 892-2500
