We do not recommend mixing together two pyrethroids such as Bifen IT and a permethrin product. These products are too similar, and you could create a repellency issue rather than allowing insects to actually contact the treated areas. If you want to add something to Bifen IT for faster intiial knockdown, then we suggest a pyrethrin and/or PBO product such as ExciteR Insecticide.
Yes, Bifen IT can be used to treat fire ant mounds directly as well as broadcast over the lawn. Please view our How to Get Rid of Fire Ants Guide for step by step instructions and a helpful video.
When treating for chinch bugs with Bifen IT, it is recommended that you do a second treatment 21-30 days after the first treatment. You will use 1 fl. oz. of product per gallon of water. This will treat 1000 square feet. Be sure to water the product in at least 0.5 inches after it has been applied.
We do sell professional Roach Bait Gel and Ant Bait Gel. Follow the links to which ever one you are inquiring about. We also carry bait granules and insecticide granules for pest control. Please read the labels for specific instructions on application.
