InVade Bio Drain is a gel that contains natural microbes to break down organic buildup in wet areas like drains. It is usually used to treat areas where drain flies will breed, and while sanitation is an important part of roach control, this is not something we would recommend for treating for roaches. We suggest our Roach Control Kits here which contain a roach bait gel, insect growth regulator (IGR), and residual spray to treat for this pest. Please also take a few moments to review our online Roach Treatment Guide for more tips.
