TERRO Drain Insect Killer
Best reliable solution for homeowners tackling persistent drain fly issues.
This expanding foam is the most effective way to clear out drain-dwelling pests that standard sprays can't reach. By coating the entire pipe interior, it stops infestations at the source and prevents them from returning. It’s a messy job made simple, though you’ll have to wait a bit before running water again.
