## Description

TERRO Drain Insect Killer provides a comprehensive solution for homeowners battling persistent drain fly infestations and cockroach problems in their kitchens and bathrooms. 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: Works but may need a few applications - This stuff works and I am pleased with the out come but it did take three applications. I live in an old house, about 100 years old and the gnat's seem to appear every summer. I also live by a lake so I don't know if that has anything to do with it. I would say it was an infestation, I couldn't eat without them buzzing around me. I am one of those people that is a bug lands in my food, it's now the dogs food so these things were maddening. (And yes, I know it's irrational to stop eating your food just because a tiny bug lands on it but gross's me out and that's the way it is.) Forget about drinking red wine because they love it and land in it immediately. In any event, the gnats literally drive me crazy. I hate them! I have tried everything to get rid of them. The vinegar, soap, water traps. The lights with the sticky cards. Anything I could find. These traps catch the gnats but they don't get rid of the problem. I saw this and thought I would give it a try. I ordered two cans to start with because I have three full bathrooms, a utility sink, plus the kitchen sink. The first time, I performed the application at night on July 7th and then went to bed. I used both full cans, which was mainly because I was figuring out how to use it properly and I put almost a full can in the garbage disposal. I would say in the next couple of days you could see a significant reduction in the number of gnats and I found several in my bathrooms dead. I figured it would take a couple of applications due to the other reviews that I read. Within about four days, I saw them beginning to increase again. I ordered two more cans and applied about 1.5 of them the night of July 12th. That is 5 days following the first application. Following that application, there was another significant reduction in the gnats and I was still finding dead gnats on my bathroom floors. After the first two applications there was a significant improvement in the quality of my life. Just chipping away at killing these gnats and I was/am determined to rid my house of these pests! Ordered two more cans. I was leaving for the weekend so I thought a perfect time for another application and then it would be able to sit for a couple of days. Applied another ~1.5 cans on Friday afternoon around 3:00pm on July 18th. Returned Sunday July 20th early evening. To my shear delight, I did not see any gnats! Monday, I saw one gnat. Tuesday, I saw one gnat. Wednesday I did not see any gnats. It is now Thursday morning and I have not seen any gnats. I am hoping that is the last of them but I still have enough product for another application if it is needed. So, in summary, it has taken me close to four cans to fully eliminate them over the course of 16 days. I ordered a total of 6 cans at a price tag of $95.82+tax so over $100 in total, so not cheap. Also, pretty sure the stuff is toxic because it says something about hazmat on the label for shipping. Hope this helps.
Review: It worked (eventually), no allergies - I tried several recommended techniques to get rid of drain flies. This is the one that worked for us, but it took about 3 weekend treatments. I really like that it filled the drain pipe so you know when to stop spraying and you can treat the overflow drain hole easily. One of the positives is that my wife and I were not allergic to it. Some of the "natural" drain products are smelly and caused us both to go into sneezing fits

### ⭐⭐⭐⭐ Good in combo with other products to rid of drain fly infestation
*by Y***S on February 13, 2026*

Nice foam and good to use to fill drain to help rid drain of drain flies but if you have a real serious infestation you will need this plus Green Gobbler for drain flies and Gentrol Complete EC3. This product weekly and the other 2 daily until 2 weeks after drain flies are gone. Zevo lights help too.
