Say goodbye to pesky gophers with our Tunnel Fill! 

No poisons or traps. 

Simply add water to Tunnel Fill  and watch it expand, deterring rodents from returning to your property! Tunnel FILL  seals the holes with natural ingredients and no special license required - it's biodegradable, non-toxic and safe for your family and pets! Gain peace of mind, with the Tunnel Fill and Tunnel Plug Combo.

Tunnel Fill is designed to effectively prevent landscape or yard damage caused by burrowing rodents. When applied, Tunnel Fill rapidly expands and forms a sticky mixture like applesauce, that is further reinforced by the Tunnel Plug. Natural spices used in the formulation repel rodents, making sure they stay away from treated areas.

One Tunnel Fill tube fills up to 50 ln ft. of Gopher Tunnels after water is added! 

Tunnel Fill can be used with any burrow including gophers, moles, squirrels, ground hogs, woodchucks, voles, skunks, badgers, rabbits, and more!

Seal all gopher entrance/exit systems with a Wonder Soil Tunnel Plug



Coco coir, natural spices and potassium polyacrylate polymers.


How to use Tunnel Fill:
Find the rodent's burrow and pour a handful of Tunnel Fill down the hole. Use your hose to flush water down starting on high pressure for one minute then medium pressure for two minutes. Go to the other end of the tunnel and repeat. Tunnel Fill will expand to completely fill a tunnel as it absorbs the water. Please wait after you add water for the product to fully expand!

1. Place Tunnel Fill on the entrance hole or in a container.
2. Slowly add water and mix well.
3. Plant directly on top of the tunnel plug!

How much do I need?
There are lots of variables to this including how extensive the tunnels are, the target and the quality of your water. Higher quality water allows more absorption so lower quality water will require more product.

An average gopher tunnel system in Southern California where our product was tested took about 1/2 of our small containers to fill one system. A system is several mounds, feed holes, nests, food storage areas etc.

We would recommend buying two pounds for most small areas You can always buy more product if needed but this is enough to do a few systems with some product left over in case of a second application or future gopher activity. If you have a large property a small property with a large number of tunnel systems 4- 5 pounds may be a good starting point. Again, you can always purchase more if needed. Farms, parks, golf courses and other large area facilities may consider 50 pound purchases most economical.

Pest control companies wishing to add this product to their available services would probably start with 50 pounds. This will fill 40-100 systems depending on water quality, how big the systems are, etc.

Waste of money

This stuff won’t do a damn thing. Totally waste of money and time.

Jeff Irving
Tunnel Fill

Appears to work but the round disk size can be too large for small tunnel. Used in past and fill was more like small pellets vs large disk.

Fred B
Didn’t work well

Probably needed more, one tube was not enough. By the time I ordered and received a full bag the gophers blocked the entry and are still at it. To be continued.
