Having roaches come up my drains and would like to put something safe down the drains to get rid of them but not upset the balance of the septic system. If it is safe, how much would I use?
Cynoff WP cannot be used in a septic system nor can any other insecticide we carry be used down drains. Roaches would only be coming from the drains if there is a crack in the pipe allowing them to come in. You would generally only see roaches coming from drains after they have gone down to get water. For roaches in a home we would recommend one of our Roach Control Kits and also have a great guide that explains the best treatment to eliminate them.
