## Overview

TERRO Drain Insect Killer T590 uses a unique dry foam with three Insect Growth Regulators to deliver 360-degree coverage inside drains, breaking the life cycle of drain flies, fruit flies, house flies, and roaches. Its precision extension tube ensures targeted application in all pipe types, including septic-safe use. Regular treatments prevent reinfestation, making it a top-rated, professional-grade solution for lasting pest control.

## Description

TERRO Drain Insect Killer is a powerful solution designed with a dry foam formulation that contains three Insect Growth Regulators (IGRs). Unlike liquid drain products, this unique formulation reduces the chances of missed areas and provides full-contact, 360-degree coverage, making it highly effective in tackling and preventing insect infestations. The IGRs in TERRO Drain Insect Killer disrupt the normal development of immature drain flies, fruit flies, and roaches. Additionally, it disrupts the normal life cycle of drain flies and fruit flies, effectively eliminating them during their pupal stage, thereby breaking the cycle of infestation. To effectively use TERRO Drain Insect Killer, apply the foam into and around the downspout and catch basin to cover the entire area. When treating a double-basin sink, be sure to apply it in both drains. Use the convenient fold-up extension tube for precise application into the pipes. 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 product can be used on all types of pipes. Depending on the severity of the infestation, it's recommended to repeat the application every 2 to 4 weeks.

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.
