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 the 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!

Not sure it worked or not

The groundhog holes were huge and I either needed to fill the holes first with rock and dirt and then the two products or buy a bucket full of products. I did witness the expansion of the 2 products but I needed to do the above.

Loved iso far no gophers

Works as Advertised

First time using and is for those pesky ground squirrels. Easy to apply and works as advertised. Just applied two days ago and just waiting to see how it’s at preventing them from returning. Otherwise would give a rating of five.
