What's the best way to use NyGuard IGR in addition to using drain cleaners for home drain fly problem
If you are looking to use NyGuard IGR in your drains for drain flies, the product label states, "Foam Application: For the control of drain/fruit flies, combine Nyguard IGR at the rate of 4mL to 8 mL concentrate with 1 gallon of diluent. To convert this diluent to a foam, add foaming agent at the manufacturer's recommended rate. Using a professional foam applicator, apply finished foam to areas of fly breeding such as drains, traps of sink, bathtubs and in floor drains. For best results, foam should be applied thoroughly, ensuring all void areas and fly breeding material is treated. Follow the requirements of the foam equipment manufacturer."
If this type of application is not something you are willing to do you can use Gentrol Aerosol IGR in the drains instead.
