Tunnel Fill Tube

I had some pretty large holes but wanted to try this product anyway,(understanding that I'd have to do more work after) and it works as advertised. Expands quite a bit and was easy to flush down the hole. I figured I will use this to deter them (Fill your house with dirt and garlic smell, you'll leave), then come back and compact it down and throw some old pavers on top. So far they're not back to those spots, but its been only a week or so.
If you're filling a hole, consider: (1)are you planting anything there? If so, a soil replacement like this may definitely be worth the price hike.
If you're not planting anything there (So, you don't care about maintaining soil composition), you can probably opt for a few cheap bags of pea gravel, quickcrete, maybe sand, etc. (If you refill with normal dirt they will just dig it back up)
(2)How much volume do you have to fill?
This product (In this quantity) seems especially good for small rodent holes in an area where there needs to be good soil (lawn/garden). (My definition of small hole would be <3in across and <12in deep).
If your holes are larger or you have tons, I'd advise the large bag, and/or looking for another solution, like beefing up your garden's fencing.
A bit of a long-winded review, but I figure some day there will be at least 1 person wondering the same things I was before I bought this, so now they'll have some reference.
Happy gardening everyone!

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

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.

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.

Wondersoil Tunnel Fill allowed me to rid my yard of the critters that had taken up residence, and destroy their burrows in the process.
