Just talked with my brother-in-law tonight. He had a nest and used
Sevin a short time ago and the Sevin worked for him.
I had a few ground nests last year, one was big enough that the Sevin
wasn't working (or at least not as fast as i wanted), so I got out the
Here's some tips for gassing the nest-
get a small glass jar- i used a small 8-12 oz empty salsa jar. using a
small container has several benefits- you know exactly how much gas you
are dumping into the nest, so you don't have a giant explosion near you
when you torch it. Also, you don't have a gas can to move away before

dump or spray something on it. I don't know which critters do the
digging, but it usually happens overnight. I have had this happen
several times, usually in the fall, when the nights get cooler.
