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.
