With so many products out there, it is overwhelming, particularly when trying to figure out what can be used together and how to use them together in a safe manner. Toxic chemicals (particularly carcinogens) are pretty scary. While I do not own a pet and have never had flea problems before, I found 4 the other day. First time and have no idea how they got there. Is IGR safe to use with diatomaceous earth, Permetherin, and if so, what it the recommendation (instructions)?
You can safely mix Precor IGR with Permethrin and apply as a broadcast spray on carpets and under furniture. You can also use diatomaceous earth in areas listed on the product label in a home that has been sprayed with permethrin/Precor. Be sure to read and follow the product labels for best results. Also, vacuuming prior to the first treatment and every other day for 14 days following the flea treatment will help get rid of the fleas much faster than spraying alone.
