When doing a soil barrier treatment for termites, it is important to treat directly against the structure on all sides of the house as close as possible. Against the foundation of the home, dig a 6 x 6 trench around the entire perimeter. Where carports and concrete patios are existing, you will drill 18-24 inch holes 2-3 inches off the foundation wall 10-12 inches apart. This will ensure the soil under that concrete slab is protecting the actual house foundation. Please read our on How To Perform A Termite Treatment Article for more detailed instructions and recommendations.
While Bifen IT is labeled for termites and will last up to 5 years in the soil, we would recommend using Termidor SC or Dominion 2L for termite soil barrier treatments. Termidor SC bonds to the soil after 24 hours and will last 10 years and Dominion 2L will last for 7 years.
Yes, Bifen IT is very gentle on turfgrass and other ornamental plants. You should use 0.25 - 0.5 oz per 1,000 square feet to treat leafhoppers.
We are not sure what type of worm would be considered a "red worm" as you have described. Â If you are referring to earthworms,Â Bifen ITÂ isÂ not labeled for earthworms, because they are a beneficial but it may cause harm to them if they contact a treated area. Â Though they are pretty protected by the mucus on their bodies. This small amount of product needed to kill tiny insects would not be enough to harm a bird if they were to ingest a worm that would have contacted the product.
You do want to spray Bifen IT over the sod periodically to keep the rest of the population on top of the new sod down.
Bifen IT cannot be used on areas that will be used for grazing by animals.
Yes, Bifen IT can be used both indoors and outdoors.
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.
