If it doesn't work well, what is a good chemical to use for knock down and long term residual? Besides a trap/cup.
Gentrol is a product used to sterilize fruit flies. This means it will keep them from reproducing, it is not a product that will kill adult fruit flies. For knockdown of the adult fruit flies, you should use 565 Plus Aerosol or Clean Air Purge.
