TERRO T800 Garbage Guard Trash Can Insect Killer

I attached this device to the inside lid of one of my outdoor garbage cans with a zip tie which I ran through the small holes that surround the unit. Prior to installing this unit I was having a horrible time with maggots all over the inside of the can. I bag up the trash in the can and take out to the curb on Fridays and usually have to wear rubber gloves to keep all the maggots off my hands. Since putting this unit on two weeks ago, I haven't seen a single live maggot. What I have seen is about 5 dead flies and 3 or 4 dead maggots laying on top of garbage in the can! This can gets the kitchen trash as well as dog "mess" from the yard. So you can imagine the amount of maggots that can build up in there in a weeks time... 1000s. I can't say how long this device will be effective as I've only been using it for a couple of weeks, but when it stops being effective, I'll come back and update this review. In the mean time, I am about to purchase a few more to make sure I get through this scorching summer we're experiencing. **UPDATE: Just finished week 4 with this product and I've noticed between 10 and 20 maggots alive in the trash can. There is no way that this item will keep maggots away (or kill them) for 3 months. That said, I will continue to use this product, even if I have to change it out after only a month, because to do otherwise means that I'll be dealing with a HUGE amount of maggots every Friday when I have to tie up the bag and set it out on the curb. I will take away a couple of stars though; one for each month short of the 3 months mentioned on the box.
