TERRO Garbage Guard Trash Can Insect Killer, 2-Pack

Product is excellent but it has stick on tape only one side. I have had to buy double sided tape.

PICTURE THIS: I walk outside into the darkest of nights, carrying the days trash and armed with a simple flashlight. I spot the trash bin, shine the light, and TO MY HORROR is see that it is completely covered in maggots! Being the valiant knight that I am, I called my wife to be a witness to this horror. She stepped outside into the disgusting maggot filled world and immediately made the decision to grab a gas can and burn it all down! I stepped infront of her and my heart stopped. My wife glared. And I, in sheer panic, found myself awkwardly bargaining, “What if I just burn the trash can?!” Cue the smell of smoke… or was that terror? Then I discovered the Terro T800 Garbage Guard Trash Can Insect Killer—an unsung hero in pest control. This compact pod (treats up to 50 cubic feet) adheres to the inside of trash bins or dumpsters, releasing a silently potent, odorless vapor that penetrates deep to kill flies, roaches, maggots, beetles, and forest reserves of teeny trash‑can critters. It’s controlled-release technology at its finest, long‑lasting up to 4 months. Installation? So easy even my trash-phobic self managed it—just stick the adhesive strip (best to clean the lid first), pop it inside, and close the lid. No residue, no fuss. The result? A fly killer, insect prevention, maggot deterrent all in one tidy, odorless package. I slapped that little pod into the can, held my breath, and… watched the maggots vanish. It was like someone hit the “reset” on trash infestation. My wife stopped drafting the fire permits, I stopped sweating actual flames—and tranquility was restored. In short: Compact and easy-to-use insect killer for trash cans, outdoor or garage Deep-penetrating, odorless vapor kills and prevents pests Treats large bins (up to 50 cu ft) with just one pod Lasts up to 4 months—“set-it-and-forget-it” bug defense Pure comedic relief: no more maggot horror scenes, no more kitchen arson threats So if your garbage can becomes the next maggot incubator, skip the lighter and grab the Terro T800 Garbage Guard—your odorless, fly-killing peace-maker. Trust me, marriage counseling (and fire insurance) will thank you.

I have been using Terro garbage guard a couple of years. The actual product works great. It does what it is advertised to do, kill all of the flys, knats, and maggots that once infested my trash cans, Quickly. This would be 5 star review on effectiveness for sure. Had to give it a four star review solely based off of the adhesive strip. It doesn’t stick well. I had quite a few fall off into trash can and get loaded on garbage truck with trash. Product too expensive to be lost after a week or two. I purchased double sided gorilla tape and use that now. Haven’t lost one in trash since. So I recommend this product to kill the insects, but you will need to purchase a better quality double sided tape.

Here’s the thing. It works great killing flies in the garbage can. But the sticky thing they give you to mount the pod does NOT work. You can only peel off one side, so it’s only adhesive on one side. It’s defective. After losing one to the garbage truck, I devised a way to hang it with string into the can. I can remove the string and the pod on trash days. It does work. It’s just difficult to mount it.

They work! most of the bad reviews are because they don't stick on or stay on while using the peel off of stickers. Because of that I took a different approach and ran a wire through the plastic and attached it to the inside of my trash by hanging it from the back where the lid attaches , it's been on for 2 months, No issues. No Flies. However July & August will be the true test when more flies are breeding. I have two dogs and pick up a lot of their pooh in my backyard and put it in small grocery bags so every year I get tons of flies and at least once a year in hot Ohio Summer get maggots. Ill update my review end of July.

We just moved into a recently renovated/flipped home. Everything was brand new and the home was clean, clean, clean! But, we had this horrible problem — flies! We couldn’t open the garage door or take out the trash or even come in the front door without flies getting in. Considering how diseased these critters are, I didn’t want them in my home. At one point I had killed 10 in a single day.. in my home! Enough was enough! We had purchased one of those rectangular zappers you see, rebranded a thousand times, for $40 on amazon and they do work great (although loud and a bit scary to handle.) Even though it was killing our active flies, the problem still persisted. My friend told me to wash out the trash can outside (the likely source of these flies) with bleach and soap water after the trash had been taken. So I did. I bleached and watched all those larvae go toodles into the soapy and bleach abyss. I thought that would be it. But, nope! Two days later, I’m taking out the trash and lift up my trash can and am met with a swarm of no less than 30 flies. 30!! Where did they come from in two days?! So, I turned to Amazon once again. I saw that Terro had a garbage guard for $7 that had decent reviews. So I figured it wouldn’t hurt. I risked it and purchased the Terro T800. It arrived the next day. When I got it, it didn’t smell like anything. It’s super tiny. I thought in NO WAY would this thing do anything. But I stuck it anyway to the garbage kid, and like another reviewer suggested, I put it by the hinge to help prevent it from being knocked out by trash. Then, I close the lid reluctantly. I was pretty sure this tiny, non electrical, non-smelly thing wasn’t going to do SQUAT. Like all the vitamin reviews on Amazon, I was pretty sure any review was made up. But, I left it alone. I came back two days later to take out more trash and was preparing my fateful demise involving 30 more flies. My hand went up to my face. I made sure to close my mouth — you know, just in case. One fly. One came out. WHAT? I look into the trash can which has been previously alive with maggots and saw none. NONE. And what I saw were a bunch of dead fly bodies. Those horrible vermin were gone. This must have what it felt like to be Dexter.. I have officially wiped out the enemy with punishable death. Two days later I return and just a moth comes out and the flies are still dead. It’s been a week and I have not had to kill a single fly in my house. It’s been a week and I have not had to suffer the annoying sound of the bzzzz behind my head as I read a book and then turn around with anger, “Where are you!” I no longer have the guts of flies smashed on my palms as I smash them against the window in my vain quest to rid them from my house. To think, months of suffering with flies and all I had to do was get this Terro Garbage Guard. It is $7 with prime and will be the best investment for you! I cannot recommend it’s enough. Thank you, Terro, for giving me my sanity back.

**UPDATE 5/3/26:** I have revised my initial 1-star review to 2.5 stars, but since I was only allowed to give either 2 or 3 stars, I opted for 2. The reason for not awarding more stars is that half of the product failed the adhesion test. The Terro T801SR is marketed to kill flies and adhere to the lid of a trash can, but it failed to meet one of its key selling points. My initial review was submitted in early August 2025. I placed two pods on the lids of our trash cans; one came off within five days (before trash day), while the other remained attached at the time of this review. As of today, the second Terro T801SR pod is still on the lid of the trash can. When I installed the pods, I thoroughly cleaned the area with Dawn Platinum spray (which I love) and a damp scrubbing sponge, then wiped it down with a damp rag. After ensuring the area was dry, I peeled off the tape and secured the pod to the lid. I am confident that there were no contaminants on the lid where the pod was placed. The one that failed seems to be an issue with the tape. While one pod is still holding strong, a 50% success rate is not ideal for any product. **Initial Review (Early August 2025):** This review primarily addresses issues with the product's setup and design, rather than its effectiveness at killing flies, which appears to function as advertised. I had concerns about the product's reliability after reviewing the placement instructions. The case includes a piece of double-sided tape intended to adhere both to the case and the inside of the trash can lid. This design introduces two potential failure points: the tape could detach from either the case or the lid. Additionally, every time the lid is opened and closed, force is applied to the tape. Since we add trash to our container several times a day, this creates constant stress on the adhesive. On trash day, the truck dumps the container with additional force to ensure all contents are ejected. We have two containers, and unfortunately, one of the pods failed to last until trash day; it only stayed on for five days. The other pod is still attached, but I doubt it will hold up after the trash is dumped.

The product seems to work well & for a long time. Thus, I give it 4 stars. However, like many others, I have had issues with the adhesive. I know of at least 2 times (possibly more) they didn’t even include the adhesive patch with the product. The other is, I’ve had to replace the whole thing because the adhesive didn’t hold and the guard was gone. I’ve read a few ideas from other reviewers for workarounds. I do have to say that I find it somewhat frustrating that the adhesive has been completely left out of the packaging, multiple times.

The product isn't working as it was shown. The package seal was loose. The double side tape was missing. The flies wasn't seen for a day or two after that the product seemed disappeared for flies or may be the flies were using some kind of mask to avoid the smell. It's been over a month and not happy with the results.

Reading the previous reviews, I was a bit skeptical byuing it. But I can tell you that it works well the day I put it in. Flies are still around the bin but always ended up dying. No more maggots and bad smell. So happy. Back to buy a couple more. 100% recommend this products.
