The Gopher X Carbon Monoxide Sprayer manifold assembly requires no regular maintenance. The hose and oil fill valve are high quality parts and usually only require replacement if physically damaged.

However, the engine will require the same maintenance as any small engine; periodic oil changes, air filter cleaning, etc. The manufactures manual that came with your engine will have the maintenance information in it.

No, the motor will run and still produce carbon monoxide. However, there will not be any smoke to see where the gas is going or if there are any uncovered “air” holes. It is an important step in the effectiveness of our gopher products.

An average run time of 3 minutes tends to burn off one application of oil. You will know that there is no more oil in the manifold when you no longer see any smoke coming out of the silicone hose end.

No, this is the oil being burned off in the manifold and then pushed into and through the gopher tunnels. You will want to cover the hole with some dirt to keep the smoke from escaping the presence of the target gopher. Products used properly will result in optimal, ‘gopher be gone’ results.

The yellow cup, on the manifold fill valve, holds ¾ of an oz. of oil. This is the recommended amount of oil for one 2-3 minutes application. We recommend one 3/4 oz fill per application cycle. Two fills are recommended anytime you need to use the choke on the engine but in any other circumstance it will just result in wasting oil.

No. When the valve is opened while the machine is running, oil and exhaust fumes will be expelled toward the operator, possibly causing injury. In your pursuit of gopher-be-gone at your property or in your lawn care company, please be a safe operator.

No. If oil is left in the manifold it will not harm anything.

No. The blue hose that comes with your Gopher X Carbon Monoxide Sprayer is a high-quality hose that is rated to handle high heat. If you handle the hose during or after operation of our gopher products, we recommend work gloves for your protection.

We recommend you flatten out every mound first. The next day you will be able see the newest mound and that is where you will want to start. Try to locate the end of the specific tunnel. This may be the mound farthest from the rest but most likely the newest and freshest dirt (where the gopher stopped digging for today). This will ensure you sending the treatment in one direction, thus keeping a concentrated cloud of carbon monoxide.

Two possible reasons:

1) An established gopher run can be as long as 50+ feet, with several pockets and offshoots for food storage, nesting and waste. When a well-established gopher tunnel exists it may require more than one application with our gopher products, as at the time of smoking the exact location of the gopher is unknown. Be patient, as most gophers end up tunneling into your yard from a neighbor, canyon or field and they have a place to retreat to. Continue the treatments and you will either kill the gopher or back him into a corner he will not be able to run from.

2) That gopher did die. Gopher be gone; it worked! Most tunnels contain only one gopher, however once that gopher is dead, other gophers may, and very often will, use that tunnel as their own. (This is especially common in heavily infested areas). Therefore, it is not uncommon to find more mounds in the same area only a day or so after eliminating the original gopher. The new gopher will dig around the dead gopher and then push the newly dug dirt out the end of the tunnel. That is the new mound you are seeing and it may occur numerous times in a heavily infested area.

Yes. Gophers can dig in both soft and hard soil. We have seen that soft soil, “sandy” soils or well-watered lawns allow the probe to go through the dirt easily and make it hard to tell when you hit the open tunnel. Also, this type of soil is more likely to collapse tunnels when a riding lawnmower is used on the lawn. This means that a gopher will make more mounds as they have to rebuild part of their tunnel system. This also means that it may take several applications to get the right tunnel and see that gopher be gone.

If you only had one gopher then you should be gopher free for quite a while, however, that would be rare. Therefore you must regularly check for new mounds. Gophers can, and will, come in from other areas and new damage can occur in as little as a day. If your property borders other infested areas then you can expect gophers to reinvade regularly.

Squirrels generally have two holes into their burrow; however there may only be one or there may be many. If you cannot tell which hole is active, cover all of the holes with just enough dirt so that you will be able to tell if a squirrel went in or came out of a specific hole later. Once you identify the new open hole, insert the Gopher X Carbon Monoxide Sprayer hose inside. Place a small amount of dirt over the hose to cover the hole and start the treatment process. Every rodent can be outsmarted with our gopher products.

We call that “blow back.” That is when the lower part of the tunnel is either plugged by the animal or it is an old, blocked tunnel and not being used. Turn off the machine and probe for another entrance. Our gopher products serve to solve your problem once and for all; gopher be gone!
