Wonder Soil is great! It's clean, my plants love it and expands as it claims! It's my preferred choice.
Wonder Soil is a very good potting medium.
I applied one combo pack to a system of rat burrows over 100 sq feet. That night, we watched a few escapees return to try to get back in... with no luck. We've been fighting this for months with poison and traps with little success. I'm optimistic we turned a corner now that there's no where for them to live. And it's way cheaper than an exterminator!

This doesn’t go anywhere near as far as I was hoping it would and thus it is VERY expensive. It does seem to work though. I had a small hole near a gate that I tested on. It took about a half a canister plus two plugs to fill but the squirrels didn’t dig it back up the next day. So the only problem is that I have major caverns to fill throughout my yard and I will probably need a prohibitive amount of tunnel fill to do it.
