TERRO Drain Insect Killer, 1-Pack, Foam Treatment for Indoor Infestations

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!

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.)

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.

This is a wonderful product. I finally got rid of the 🪰 fruit flies. There was enough product to clean each sink (3) times and a bathtub and a shower drain twice. Totally amazed.

The larvae in the photo are Drain Gnats. They were not in my drain but in the cracks of my tile where the shower floor meets the wall. Once through the cracks, it must open to a large space behind the shower wall -- PERFECT for the expanding foam of this product! When i blasted into the crack the foam leaked out of cracks back into the shower 2 feet in each direction!!! It was a huge hiding spot for them!! The next few days the larvae worked their way out and expired on the shower floor. Mission accomplished!

I tried for months to get rid of pesky drain flies. After spending hundreds of dollars on dozens of products, I finally bought Terro. It worked after the first application. Easy to apply. No odor or after effects. The right size for multiple applications, if necessary. I will always keep a can under my sink. Saved me lots of money.

Works, but stops foaming after the first use. So you only get one shot at solving the problem. Even when there's clearly over half a can left, no matter how much you shake it, it stops foaming after the first time you go to apply it.

I was having fruit flies flying in rooms no where near the kitchen-even upstairs! Terro fruit fly traps and ant gel are very effective, so I turned to Terro for the drain. I sprayed it in two bathroom sink drains and the shower drain. No more flies, and it has been 3 months! (I also read to wash bananas as soon as they come into the kitchen and do this, too).

ممتازه جدا جدا ومفعوله قوي وسريع

easy to use

Great

While spraying the solution stays liquid, and drain flies just escape via the drain back up.

Foaming is weak
