(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

This mole killer was our last resort for the monumental mole problem in the ground around our house. It seems to be effective, but our work is still in progress. Fairly easy to use, need to watch for new excavations daily for a few weeks, as we live in the "Urban-Wildland Interface" .

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.

Only first package worked out of the 12. When we went to use another package they did not smoke at all!!! I don't know how old the product was no expiration date on the packages. Very disappointing and will not purchase again.

The Giant Destroyer is a very good product, We purchased this item to help get rid of the gophers destroying our yard and used this product and it got rid of the gophers, and they have not been back since.

For 22 years now I have tried all the brands and Giant Destroyer has always been noticeably the best for several reasons, described in my previous laudatory review, until a little over a year ago. (Purchased May '23 as the second bad box.) Many sticks in the last two cases were still excellent quality, but over half ranged from poor to unusable for the reasons cited in other reviews and photos; loose holes, mushy, crumbly, leading to failure to ignite or continue burning, ran out of fuses. **Note to Manufacturer: You were the best for decades and clearly still can be. Please, get a handle on quality control or I'm moving on to brands that have proven inferior but are at least reliable. (And few extra fuses in a case wouldn't hurt.)
