The Giant Destroyer Super Gasser 3 Packs of 4 (12 Cartridges Total)

These work! Gophers I can and do trap successfully. Moles plague me and traps are not very effective. These work! It may take more than one tries, but I get them. I shove a gasser into the tunnel and blow it in with a leaf blower so they can't outrun it or plug the hole behind them before it gets to them.

These worked well to dissuade the little guys from coming into my yard. It's not as satisfying as traps, but with a gentle fan to blow the smoke down the holes it seems to really work well. It's super easy to light and there's a lot of smoke to them.

I've used these many times and, along with some other techniques, I believe they are effective in getting rid of moles.

I have used "Giant Destroyers" for years. My local hardware store didn't carry them this year, so I bought 3 packs of 4 ea on Amazon. The manufacturer changed the packaging and design of the product. The fuses are NOT installed now, and separate in package. Instructions say, put fuse in hole, but on 11, the powder/beads inside, just poured out, NO HOLE, and the one with, was more like a funnel. Not one was usable as received. When I got them, you could see some gray powder, and or small gray beads inside packaging. Check the inventory. The "New Design" is a disaster. Not one could be used as received. Looks like a try for "cost reduction" that destroyed the usefulness of every one of them. Please check Amazon inventory for "gray dust" inside package. If there, open to confirm my review. The material to produce the smoke, isn't solid, and pours out the end of the paper tube it's in. NOT ONE COULD BE USED AS RECEIVED. Somebody sure made a mistake when they redesigned the product.

Ok we got rats by the chicken coop and we blocked as many holes as we could and gassed them into a trap!

As far as getting rid of voles... they seem to work. As far as lighting them up with the fuse... I found more than half that didn't light with the fuse. Maybe it is too humid where I live? Not sure. However... I found the guaranteed method of using a butane torch. I have a push button lighter on mine. Just light up the torch, hold the Super Gasser stick on one end in one hand hold the lit torch to the to the opposite end and in a few seconds it'll bulb a little and then light up. I then shove the burning end into the hole and hold my battery powered leaf blower (on lowest setting) and blow into the hole as well. The stick won't blow out but the smoke will travel through all the tunnels. Since you can't see dead bodies it's hard to tell it is effective. I just notice that the tunnels and holes seem to disappear afterward.

Several reviews have downgraded this product as not working as advertised. I beg to differ. First, while the directions don't tell you this, a blower of some sort should be incorporated in the application of the bombs. I use a leaf blower at idle. The most efficient way I've discovered is to cut the bombs in half. You don't need a full bomb to flood the tunnel with deadly smoke. One-half will do the job. Clean out the hole, get the bomb going (either with a fuse or just hold a lighter against the end), place the bomb smoking side down in the hole and hold the blower near the entrance. You'll see smoke coming out of the ground as the tunnel complex is filled. Run the blower until the bomb is completely burned up, cover the hole and go on. You can be assured you've gotten the system filled by uncovering other hills to see if smoke comes out. If so, have another person cover the hole. If not, you have another tunnel complex to take care of. If they reappear in a few days, it's because new moles have taken occupancy. Remember folks, these are rodents and they multiply like, well, rodents. Keep after them in this manner and you'll get the upper hand.

What I do with these is I stick them in the hole and then set my leaf blower over the hole to make a kind of seal and blast the smoke all through the tunnel system. I'll see smoke coming up from openings 25 yards away. The leaf blower allows constant oxygen to get to the smoker so it burns completely and it pushes it throughout the entire tunnel system. I blast it full power for about 10 seconds and then ease off so the gas fills the tunnel completely. I've had great success with this as I live in the Utah desert and we have a major gopher population. My only gripe with these is that if they get beat up in shipping, several will be lost as the combustible material inside these bombs is easily broken up and rendered unusable.
