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

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 change I 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 see Friday 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

We finally made it to the "they must die" stage after all the broccoli and half the corn is gone...but this device doesn't even fit a muffler tail pipe. Its WAY too big for three of the four vehicles I had access to. I finally found a muffler it fits, a brand new Rav4 has a muffler protector around the muffler. We tried this device and now I think I have less gophers? I haven't seen full grown plants go under ground in the two days since I gassed 'em! I think it may have worked? I will likely have to do it again but so far, this is the ONLY thing that works at all...not noise makers or things that shake in the wind, pouring cat liter in the holes...nothing works. Gophers are cute, but they gotta go. I guess I recommend this product if you have the right muffler or plan to MacGyver it.

Was too small too fit pipes of my 2014 6cyl Ford Edge. Kinda too big for the my 2017 6cyl Explorer which has squarish exhaust pipes behind plastic bumper frame... So, I pushed it up against the muffler of my riding lawn mower. Wasn't even clamped on & noticed it was melting. So took the half-melted thing now and was able to squish it around & inside the plastic bumper and clamped it as tight as possible onto the Explorer pipe. It wasn't putting out much exhaust from the garden hose at all at idle, but at least it wasn't melting now! I reved up the engine to about 2500rpm and at least I was able to feel a lttle something coming out... Perhaps dual exhaust makes a difference on the output? I was sure to drain the water completely out of the hose. So I put the hose into the mole hole and reved the engine for 20 minutes. The mole didn't dig for a day (maybe got sick?) but then he was back. Sounded like a money saver since I have spent hundreds of dollars on gassers this year... but maybe you need an old single exhaust car that burns oil for this to work? Wish it was made of silicone to handle higher temp exhaust. I got a molehawk trap now and I am finally winning the battles in this endless war....

This thing works. I have been fighting underground varmints all summer with the little gopher flares and getting nowhere. They were sucking that stuff up like bong hits then moving on to new holes. About 500 square feet of my big beautiful lawn was a mess. Holes everywhere. You could walk on the lawn and feel the tunnels. So I ordered this thing and when it showed up(on time) I swiped a 25 foot hose out of my wife's greenhouse, backed my old dodge 4X4 that barely passed its smog test last spring through the yard gate and went to work. There were two distinct types of holes in the lawn. Little ones where the dirt mound was about 6 inches in diameter and big ones where the mounds were about a foot in diameter. I hooked everything up, cleared a big hole by moving away the dirt pile and feeling around with my fingers untill they slid into the hole. After clearing it nicely I put about 6 inches of hose down it and sealed around the hose with dirt. I fired up the Dodge and stomped down all the other big holes. I fed them smog for an hour. I repeated this process on the small holes. The next morning I took off for a week long work trip fully expecting my wife to tell me there were new holes in the lawn when we talked because nothing else had worked. Now its three weeks and my lawn is starting to recover. and there is zero signs of underground varmint activity. I almost feel bad about sending these little creatures into that long good night but I think I will get over it. Hopefully in the spring if some new rodent family decides to move in they will find all those critters taking their forever dirt nap and move on. If not...I know what to do. Kill them. Kill them all. Update 06/11/2017 Ok now I'm piXXed... While I was sleeping or otherwise occupied these little bastages have snuck back into the yard and built a super highway underneath the landscape cloth in my rock border right nest to the curb. This tunnel appears to be several 100 feet long with many entry points under the curb to the lawn. I am filling it with smog now but am afraid i might have to get a couple more of these things and run them simultaneously. I will keep posting as I battle the little SOBs. These is for keeps now.

I live in a rural area in West Texas. I have plenty of scrub property for the critters to do what they want, but they always seem to migrate towards the small portion of my land that I have landscaped. Eating the tasty roots I guess. In the past I have been purchasing an abundance of smoke bombs from firework stands. I only get two windows to stock up on them. Independence Day and New Years Day. I drop a smoke bomb in a hole and cover it up. The critters either think there’s a fire and either vacate or asphyxiate. I make sure to cover all entrances so no new tenants can move in. This worked for years, but then I slacked off. For a few years I had no problems but there was apparently a population explosion this summer and I currently have an epidemic of ground squirrels tearing up my yard and no smoke bombs on hand to deal with them. I had high hopes for this guy. The idea seemed so simple. If the exhaust coming out of my cars tailpipe can kill me then surely it can take out those tenacious little varmints. I hooked it up to my tail pipe, connected a garden hose and stuck the end of the hose in a hole and sealed it up. I ran my car for 45 minutes. I then pulled the hose out of the ground, smoothed over all the loose mounds of dirt and went in the house. Two days later the dirt mounds returned in the same spot. I go through the whole procedure again this time idling my car for an hour and a half. Pull the hose out of the ground and smooth the dirt. Two days later more mounds have returned and still in that same spot. I go through the whole procedure again this time idling my car for over four hours. Pull the hose out of the ground and smooth the dirt for a third and FINAL time. I must have Super Squirrels. Yes, I said final time. I gave up because the next morning the dirt mounds had returned yet again. Yeah, this thing seems like a good idea. If it had only worked….. I feel like I wasted my money and my time and, even though the grass is currently dormant, a good chunk of my front yard is destroyed and those critters are down there laughing at me. At least it never melted my garden hose. 12/22/18 STAND BY STAND BY STAND BY UPDATE COMING SOON MAY IMPROVE RATING 12/26/18 I've had some success. The vehicle I have been using is my 2007 Jeep Wrangler Rubicon. It does have a cat, but you would think a twelve year old Jeep with 150,000 miles on would put out enough fumes to kill a squirrel. Not so. I guess the problem is I maintain my Jeep and it apparently runs too clean to kill squirrels. After thinking about this a few days it occurred to me to use my sons old Durango. He bought it used, it was thoroughly abused and has been sitting on my property without moving for a year and a half. After replacing it's battery I hooked it up and tucked the garden hose into the same area of ground that continues to team with life. I let the Durango idle for about two hours. I did this on 12/22. No new mounds have surfaced in that area since that day. On the 23rd I tried a new area that had a severe infestation. Because the area was so big I let the Durango idle for three hours. There has been no sign of life since then. I had a third and final full on underground city over in another area that would put the New York subway to shame. I pulled the Durango up and gave that one a shot on Christmas Eve. Results here weren't quite so successful. Two things happened. For the first hour things seemed normal. Exhaust pumping into that burrow. When I came back the second hour I found the exhaust smoke seeping out of the loose dirt. I realized the little buggers had actually taken action and blocked the tunnel to protect themselves from the poisonous fumes. They also constructed an escape route by, for the first time, burrowing all the way under the street and into the neighbors property coming up right in the middle of their caliche driveway. (He had no underground varmint issues until now.) The next day there were some new mounds of dirt so these guys clearly survived the apocalypse. So, this third attempt wasn't entirely successful. No doubt there were some casualties, but I'll try again. This one is a Huge infestation. Today was out due to rain storms, but tomorrow I'll be good to go. I've apparently wiped out two of the three communities on my property, but that last groups days are numbered. I'm actually increasing my rating from one star to four. No five because although it does work, it's not 100% effective every time. Also because the rubber cup that fits on your exhaust is big. This is so it fits over all exhaust pipes, but it's better if you have a large one. I was able to tighten it onto the Jeep without to much trouble. The cup did fold in on itself a little during tightening. On the Durango the exhaust is smaller forcing me to really tighten the clamp. As I tightened, the cup folded over on itself in multiple places forcing me to really crank it tight to minimize leaks. This resulted in some gouging and scarring on the rubber cup and with repeated use may cut all the way through making the device useless. A better design might be cone shaped or maybe step it down from a large to medium to smaller size. Wide at the open end and more narrow where the garden hose connects. It would then fit more easily on different size exhaust pipes. One concern I had was that I'm severely constricting my exhaust running it through a garden hose. Will my computer start throwing codes? It didn't on the Jeep. If it did, I have a code reader that will also clear all codes so no worries there for me. Who cares about the Durango? So, this thing apparently does work to exterminate underground pests, but it does take some time, your vehicle must idle for hours and it looks like it works better with an old beater car than one that is maintained. Also, I think the cup itself could be better designed. Once again, this never even came close to melting my garden hose. The hose I use is the cheapest most inexpensive hose I could find that I normally use to run soft water to my outdoor misters in the summer. This hose survived this ordeal without even a hint of damage. Of course, no rubber in it. Maybe that's what people use that melts?

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.

This is a great idea for a product but probably will not work for your car. I have two cars, a Chrysler 300 and a Hyundai Sonata. Due to the design of modern tail pipes, it is impossible to get the hose attachment of this product on modern tail pipes. I had to return the product. I was very disappointed as I had high hopes for this product and I have a big problem with gophers. I have tried poisons. That killed 2 gophers. I know because I saw a huge number of black ants going down into the gopher holes to eat the dead gophers. but gophers quickly learn the scent of poisons and avoid them. I went through several more containers of gopher poison with no more kills. I tried gopher traps but it takes a huge amount of work to properly dig down to the right tunnel, position the traps just right without having them snap on your fingers, etc. I do not have the hours of time it takes to mess with traps. So I had high hopes for this product. But as I said, it probably will not fit on your exhaust pipe unless you own a 1956 Studebaker pick-up or some other vehicle with a long skinny tail pipe that does not have a decorative covering that makes it impossible to apply the necessary clamp to keep the hose attached. What this company should do is sell a small cheap gasoline engine along with this contraption and I would buy the whole thing to get rid of those destructive gophers! Like tens of millions of other people, I do not own a gas powered lawn mower (i have a gardener) and I don't want to buy one. But I would buy an all-in-one system for pumping a huge amount of gas down gopher holes to finally get rid of this destructive pest. Like I said, this is a great idea for a product but probably will not work with your vehicle.

It really works and saves money over the mole-killing alternatives
