(GAS KILLER) (12/4PK TOTAL) 48 kills Moles, Gophers, Woodchucks, Norway Rats, Skunks, Ground Squirrels in their Holes, Tunnels, Burrows. NO dealing w/ dead pest, better than traps

Works well! Generally if I get the bombs set off on the day I first see the new tunnels the moles and gophers are either dead or gone for at least three weeks! Sometimes I set off one nomb sometimes it’s five to 8! They do work if I am paying attention. Great pricy!!!!!

I've used these before with ground squirrels and did not have success...I think because it was already winter time and they were already hibernating. I managed to get rid of them for a year but they came back last year. I let it go, but they are sooooo destructive that I just couldn't let them continue to burrow around my front and rear steps and create trails in the yard and dig away from the roots of my shrubs and trees.I read where these are more successful in the early spring/summer. My whole family went to town one morning quickly filling the holes with these smoke bombs and covering with dirt afterwards. There was one that must have been away and came back. After about a month I finally saw it eating grass outside the hole and immediately grabbed more of these bombs and dirt. When it saw me it went down the hole and I quickly lit a bomb and placed it in the hole and covered with dirt. Haven't seen it come up this time.It would be nice to not have to eradicate these creatures, but services are extremely expensive to trap and release and all you do there is cause a problem for somebody else. If they weren't soooooo destructive I'd let them stay around my house. Just too expensive to let them destroy your property.Bottom line is I would recommend these in the spring/summer when they are making babies. Best to do it early morning when they sleep or wait till you see them and chase then down the hole so you know they are present. Plug all holes or wherever you see smoke come out.I hope you never have to deal with these critters, but if you do, this is a tool that can help you eliminate the pest.

I have a large prairie problem, the Giant Destroyer helps a lot. Don't expect a "one-pass" miracle cure, & plug up those air holes & all that... Because I can't tell which holes are related to a single burrow, I probably drop several into same burrow, but with the couple hundred holes I have, I'm fine with overkill.My method:- Initially I used 16x16 playwood pieces to cover the hole & loosened up dirt before lighting to pack around the edges..which probably gave more warning so some of the varmints could collapse the tunnel & thus survive. Initially had good results, not great.- Solved that with 4 "butterfly sandbags" (for photographer & AV work), plus somewhat thick welding splatter cloth (all bought here from Amazon). Fill the sandbag maybe 3/4 full so its easier to seal the hole. Light fuse, drop into hole, place cloth, slap sandbag on top. Move on to next hole - with 4 bags & clothes I stay fairly busy, could use even more. (Hint: one of the sandbag makers used neon-ish color striped fabric, easier to find as they are scattered across the prairie.)- When I remove the bag & cloth, I shovel & flatten as much as I can, so I can tell later if either survivors or new pioneers from elsewhere keep this an active hole.- Bic lighters sucked big time on my first day. A decent rechargeable cigarette light - the "arc tip" type - works incredible fast & well at lighting these fuses, and wind no longer matters. That was one of the most important pieces for me.- Missing fuses - the biggest reason I give the product 4 stars - I got 3 not 4 fuses in about 1/4 of these packages, and that's after factoring in the occasional package with 5. None of the vendors supplying Amazon responded well to queries for buying more fuses. I found a manufacturer web page, emailed the address given, they cheerfully and quickly offered to mail me some. GREAT help there from the maker.- My biggest problem is staying clean - after 2 monster passes thru my "front 7 acres", maybe 90% of holes were inactive after 5 days, but 2 weeks later, a significant number were opened back up from my back pasture & a bit from neighbor's land. Therefore - I'm ordering another 2 cases & planning a weekend party to re-smoke the front 7, plus make a monster pass thru the back pasture. I believe hitting the whole property, just before breeding season, should reduce the "reserve troops" in that back pasture down so I'm in much better shape even after breeding & birthing season this spring - then with luck will only have "routine maintenance".- I supplement with the tailpipe-to-garden-hose method, which helps really permeate sprawling & persistent burrows. Dual exhaust is nice so I have 2 setups & keep the hoses in those holes, especially on big burrows, a long time.For prairie dogs the Giant Destroyer product is not a miracle cure but pretty darn good, and kill rate goes up with experience. This method takes some real time on your part. And for me with a lot of holes, not cheap - but cheaper than the professional fumigators - once you knock 'em way down, respond fast to the "exploratory expansion holes" & stay persistent.

I have used these for many years with moderate success. This last batch is less than satisfactory as the flare stops burning or sputters and dies way before completion. The fuses work but fail to ignite the flare. There must be a quality control issue as the flare mixture does not ignite or sustain combustion. It's not a humidity problem as I live in dry AZ. Bad batch. The gophers keep throwing the partially burnt flares out of their holes. Pretty embarrassing. I would not recommend it at this time until the manufacturer addresses the issue. The vendor is prompt in its shipping, just a bad product.
