This powerful roach killer indoor infestation treatment features a specialized dry foam formulation that delivers 360-degree coverage of your drain, ensuring no area goes untreated. TERRO Drain Insect Killer foam contains 3 insect growth regulators (IGRs) that break the reproductive cycle of drain flies, fruit flies, house flies, and roaches at their source. Unlike traditional insect killer sprays that only target adult pests, this cockroach killer disrupts the normal development of immature insects, preventing future generations from emerging. The insect growth regulator (IGR) technology makes this an exceptionally effective pest control solution for long-term infestation management. To effectively use TERRO Drain Insect Killer, apply the foam into and around the downspout and catch basin to cover the entire area. For optimal results, apply this roaches killer for house infestation foam into both drains when treating double-basin sinks. The fold-up extension tube allows precise placement deep into drainpipes. It's important to thoroughly coat these areas, as fly larvae tend to develop in the scum buildup on the sides of drainpipes. The visible foam formulation ensures that no areas are missed during application. This drain fly killer treatment indoor can be used on all types of pipes. The treatment should remain in place until the foam completely dissipates. Depending on infestation severity, repeat applications every 2 to 4 weeks to maintain control of cockroaches and flying insects. This TERRO drain insect killer foam delivers the reliable pest control performance homeowners need to reclaim their kitchens and bathrooms from unwanted insects. Review: Gets in tight spots and foams nicely. - I can't say if this single product cleared out my drain flies but I did notice when the foam expands it brought all kinds of gunk up from the inside of the drain. Even after I thought I cleaned it pretty good. Gunk included a couple dead drain flies. Not sure if they were already dead or killed in the form but who cares - they're dead! I found it easy to direct the spray into the drain and it didn't take too much to fill the drain. I've still got plenty left after several treatments. My mom has COPD and I've got allergies that can be triggered by odor/perfume and this product did not cause any issues. There is almost no scent. I used this after letting Zevo flying traps (UV lights) run for about a week. Also treated the drains with Green Gobbler overnight. I still get the odd drain fly but I live in an apartment so it's possible some are coming over from other units. Review: Finally got rid of our drain fly problem! - We had annoying little drain flies popping up around our kitchen sink, and liquid drain cleaners just were not getting the job done. I bought this foam treatment, and it was a total game changer. The fold-up extension tube made it super easy to spray deep down into the pipes, and the thick foam expands so you can actually see it coating the inside of the drain where the bugs breed. I sprayed both sides of our sink before heading to bed, let it sit overnight, and noticed a massive drop in flies by the very next day. It didn't damage our pipes or leave behind any harsh chemical smell, and we haven't seen a single bug come back since. ## Features - TARGETS DRAIN INSECTS: Advanced TERRO drain insect killer foam with 3 insect growth regulators disrupts cockroach and drain fly life cycles, breaking infestation patterns for comprehensive pest control in drains and pipes - PRECISE APPLICATION: Extension tube enables precise targeting of roach killer foam into drainpipes and catch basins, ensuring complete 360-degree coverage to eliminate missed areas where pest larvae develop and thrive - ELIMINATES & PREVENTS INFESTATIONS: TERRO drain insect killer foam eliminates fruit flies, house flies, cockroaches, and drain flies during pupal stage and prevents new infestations from establishing - WORKS ON ALL PIPES: TERRO works on all pipe types including PVC, metal, and ceramic drains, making this cockroach killer suitable for kitchen sinks, bathroom drains, and floor drains in any household application - LONG-LASTING TREATMENT: This innovative foam provides up to 3 months of protection.
