Underground Exterminator Pest Control Reusable Exhaust Pipe Attachment- Exterminates Gophers, Moles, Skunks, Voles and All Outdoor Underground Pests Humanely with Exhaust from Cars

I usually don’t read other reviews before writing my own—I don’t want to bias my own review. But i accidentally got pulled in to a few while looking for the ‘review this product’ button. I believe the naysayers are possibly using this tool incorrectly…My own experience has been great. I’ve used the spring traps before and they work for one mole. But by the time you see trails and mounds, you don’t have one mole, you have a community. For one trial there could be 8-20 moles, so a spring trap kill is only one battle in a long war. This exhaust tool, for me, worked in one try. I saw no more trails or mounds for 3 years.My concern for the people that this has not worked for is that they either are using it for the wrong critters or they didn’t read the directions thoroughly and a little user error has occurred.Here are a couple notes I would share:—this is not for woodchucks. A woodchuck or groundhog is the only North American marmot. They are as big as a dog, are very quick for their shape/size and are hard to trap because they are so smart. This product could handle them but I think their tunnels are too big and too intelligently created for it to get them efficiently.—you have to have a good seal on your muffler for this to work. It comes with the ring clamp but you may have to adjust how you attach it to your specific car muffler or even borrow a friend’s vehicle that fits it better.—you also have to be careful with how you insert the hose in the ground. If the exhaust is blocked by dirt or whatever, it will not work. CAREFULLY insert it. I had to get a garden trowel and basically clean out the mound of loose dirt so that I could see the trail hole and then put the hose in. Then I packed dirt around the hose to seal the opening.—the directions say to do this at night. Moles at least are active during the day—usually morning from my experience. If you do this at night, they are asleep in their burrows and simply do not know anything is wrong when the exhaust takes them instead of escaping. Also, at night, you are able to see if there are any leaks from the muffler, hose, or trails/mounds in the light of headlights or flashlights. If there are leaks, fix them and it makes the system work better. If a trial or mound has exhaust coming out, gently tamp the ground to seal it up.I think this is an excellent tool and I recommend it to all my friends who’ve mentioned mole issues. I would like to also add that I have only used it for moles as we don’t really have a gopher problem in my area.

First, I'm a homeowner that moved into a bank owned property that was vacant for 2 years. Every gopher in the neighborhood has made my yard their home.First, I tried poison bait. No luck, or at least no visible luck. Holes continued to show up at a rate of about half a dozen a day (.7 acre yard). Then came gopher gassers. No luck there either. Then, this product.So, the "operation" consisted of a 12' hose (thinking the shorter the better) and a 1986 Suzuki Samurai with emissions that should be able to knock out a gopher. But, alas, no luck. I would drive the Samurai all over the yard, locate the tunnel, shove the hose in, sometimes up to 6' down both directions. In one instance the gopher was back in just a couple hours throwing dirt out. I even tried to plink it with a BB rifle, but missed. In my opinion, this only aggravated the situation. More holes.On a related note, the device took considerable effort to obtain a reasonable seal on the exhaust pipe. The Samurai has a "small" exhaust, and is curved at the last 1-2". As much as I could clamp down, it seemed I could only achieve about a 75% seal on the pipe. I believe it would work better on the wider (3"?) exhaust.I have tried the "plunger" type traps too. No luck there.The only thing that I've had any success with is the "inside the tunnel" traps. Kind of "old school" traps, but darned it that was the last thing I tried... I landed one of them today.Good hunting... whatever your choice!

Works great when everything else failed (1k later)Except the clamp provided will not hold it on your tail pipe you'll have to go to Hardware storeAnd find one the fits your Cars size pipe correctly

I installed it on the car-no issues. drained hose, plugged up the two exit holes and the single entrance and started the car on Wednesday evening at about 745. Shut it off at about 855, unhooked from the car and left all else as it was, This woodchuck had set up household in a 'run' under my shed.Thursday morning, Thursday evening, Friday morning, Friday night all was fine.Saturday morning, one of the exit holes was opened--all the gravel was dug out!I am hoping there was a friend who wanted to visit very badly but I suppose reality will set in when I find more holes opened up!Damned things are persistent.I will await early evening and retry tonight and post a follow up note here.Follow up #1:Saturday night at 715 I restarted the process - left the car running until about 845 or a bit later.Sunday morning all three holes still covered--a temporary thing I am pretty sure.Just now-730PM Sunday, all hoes remain covered, but the hose remains buried in the main 'foyer' area, just awaiting reconnection.We'll see.Monday, Memorial Day--745AM--all holes remain covered!! If this process does not work, I will line up a diesel vehicle and see if that helps--maybe the Subaru does not make enough 'oomph' to do the deed.Again, we'll see.Tuesday morning update--730AM--all holes remain covered.Researching smoke bombs so I can determine where carbon monoxide leaks may be coming from for the probably upcoming next bout, however, apparently none can be found on Amazon--at least ones that have good reviews and ones that will not burn the place down.Again, we'll see.830PM Tuesday May 29th--so far so good!! All holes still covered and fingers still crossed!But, Again, We'll see.Wednesday Morning at 730--same exit hole open again! When are these things at home so I can give the gas when they are there? Placed plastic over the hole and then covered with gravel once again!!!Geeze.Thursday Morning at 700-same exit hole opened again! Plugged in the hose again at 755am and removed it from the muffler art 1000!!We'll see if the time changeI have to be getting close to saying I give up!as it is killing my gas mileage!!Looking for another way-maybe something like a gas bomb without any flames or maybe a toxic smoke bomb, but i think they are invincible. I am not going to trap them---pest control guy says $250 per and he will trap/remove them---all I can say it 'Wow'!Maybe the time of day change will help--the hole was dug from the outside so either they are all dead(!) and they have a visitor or the guy wants to get into the house and forgot where the front door is, but....Oh Well, we'll seeFriday Morning, June 1st:7:00AM-All Holes remain covered--I am sure they are just awaiting the right time.Oh Well, we'll see.700PM, same as 700 AM....Oh well, we'll see....Saturday Morning, Saturday Night, Sunday Morning and Sunday Night--all access holes remain intact-- I am just waiting for it to happen!!Field Camera picked up one of them a few days ago....picture attached..We'll see.Well, here it is Tuesday night and no re-entry to either of the three entrances/exits!!Kind of still awaiting the return but it looks like I may be finally be seeing daylight!If they do not come back I would guess I needed to study woodchuck wandering and at-home times.I will move my rating to 4 stars at this point and to 5 if things continue.Again, we'll see.Sorry for all the details.Well, I am kinda concerned about writing this as maybe the thing is reading but, it is now Saturday morning June 9 2018 and I am reporting that all 3 access/exit holes remain sealed!! I will finally remove the hose and return it to use in the garden!!I don't have enough patience to deal with the mole type vermin making my lawn feel like it is hollow as there are so many holes i would need many hoses--although I did help a lot by spreading the grub killer package contents all over the front lawn-where the dog doesn't roam..I am changing my rating to 5 stars and Thank all who have followed this drama.Joe
