The Giant Destroyer (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

Like all methods that trap nefarious rodent intruders, effectiveness is a function of skill, the somewhat unpredictable behavior of the animal and other interfering variables. Keep working these bombs to get the desired kill numbers. I worried these gas bombs might cause a disturbance with neighbors, who watching me ignite these gas bombs could catch a whiff of the fumes and resort to complaints. So far, nothing of that sort has happened. If following the directions, there should be very little escaping of gas product and resulting undesirable odors. Although effective about half the time, I kind of like to see my kill; some might think this is a bit morbid but then I collected naval lint when I was a kid...what can I say?! I'm glad there are defensive measures because left to their own purposes, I'm sure my gophers are intent on displacing the foundation of my home. I've lived in quite a few locations but never have I seen gophers so destructive, so bad as where I presently live. They dig up huge mounds of dirt, three feet high in places as if the Earth was swallowing up unattended items left on the side of the house. You can forget having a level surface in your yard or along your dirt road in my neck of the woods; uh huh! Not while these hairy vermin are loose. So, all these sparks and drama just to say that I'm overall happy with my purchase, no duds so far, all bombs ignited per plan, a barrage and success rate that might make Mr. Kim Jong Un proud if he were chasing rodents. Got to keep those gopher-types down!

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.

Find your way down from a mole hill to a deep well formed tunnel which won’t be collapsed a foot away, and won’t let the smoke escape absorb into porous soil or up through the grass. Not every mole hill will work. Some hills will only connect to shallow tunnels (just under the grass roots) where they feed on insects. Once you find a good tunnel, light and insert two sticks (if you can stomach the cost of using two at a time), and immediately seal the tunnel tightly with dirt so the smoke goes down the tunnel not back out at you. Keep doing this day after day until mole activity ceases. For me this is usually 2-3 days. As soon as new moles move into the area and lawn damage resumes (for me this takes about 6 weeks), repeat treatment to suppress the new infestation. I go through about 40 sticks a year on my property which gets expensive. I wish these were sold in a cheaper (and less packaging heavy) bulk format.

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.
