I used the Tunnel Fill on approx. 15 tunnels but was not convinced that the product was actually filling anything. Just seemed to disappear, on most tunnels, never appeared at the surface. A couple of tunnels that were apparently connected did fill and started to run out of the connected tunnel, but with most of them, the product just disappeared down the tunnel. My objective was to close tunnel openings to prevent voles and shrews from coming out and destroying my lawns. ALSO someone in your company needs to proofread the instructions printed on the back of the bag. Your product name is mis-spelled and there are other typo and grammatical errors. Makes you look unprofessional and does not inspire much confidence in the product itself.
