Super Gasser 3 Packs of 4 (12 Cartridges Total)

They are digging around fruit trees and killing them. Tried other things - fill the holes, chase them. When I see one and it goes down the hole, I drop one in, cover with a sheet of heavy plastic and dump dirt to seal it in. One stick might not be enough for the main burrows, but mine seem to be satellite holes they use for safety. I can't be sure they aren't escaping elsewhere, but I'm seeing much less activity. ** update ** definitely working, one stick is enough for black tailed prairie dogs. The burrows are still there, but not getting used. I guess once the next one comes looking for a new home, they find a reason (or more) to move on.

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.

i have had these take care of pocket gophers for a good long while, and i have had them fail to stop the burrowing. it kinda depends on how well you can stop up the other holes to keep the smoke in the hole. i found that if you can get it lit past the fuse, then drop it down the hole, then get a scoop of dirt on top of it to contain the poison underground it works well. i get to practice whenever the nearby golf course exterminator does his thing over on the greens...i probably eliminate some and send the rest right back to the third hole.

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.

I have used this product before and it has worked. This time it took several tubes of this product dropped in the rat hole at one time to stop the activity but it does seem to have worked. Now I just have to block their return using wire plaster lath.
