## 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: Excellent product! - Spent years trying to get rid of fruit flies, so glad I tried this. I noticed most of them around my kitchen sink so thought this might work. I used overnight and 90% of them are gone! I have some strays in other areas but they are easy to manage. GREAT PRODUCT!
Review: Going crazy! This works. - I have tried everything from apple things, blue light things, green gel stuff, drain clog stuff, powder foaming stuff, bug zapper in the house and gallons of hot water. This foam gets in the crevices of the over flow in sinks and around the edges of walk-in showers. We talked with a professor at Mississippi State and he determined we had phorid flies which breed in drains or any organic scum matter. The trick is breaking the life cycle. They look like fruit flies but have dark eyes. When we sprayed the foam in the drains and over flow, flies started coming out of the drains. We covered the drains overnight. We noticed a big difference the next morning. It gets about 4 to 5 drains per can. The trick is shaking the can several times while using the spray to maximize foam. It is pricey to do all the drains every night for several nights. However, it was this or sell my house. (Tip: Undiluted 99% alcohol in a spray bottle kills the flying adults.)

### ⭐⭐⭐⭐ Costly when it don't foam right.
*by J***H on June 19, 2026*

Don't always foam. This stuff works. When the foam come out like shaving cream it lasts a long time. The problem is it don't always foam like shaving cream. When it don't foam right it will not last long. You have no way of knowing how well it work until you try it. I have tried 4 cans out of 6. I will not buy again. To costly to be guessing.
