Duane is right about the D-Con but you need to keep it inaccessable to
neighborhood cats, dogs and kids. Rats love enclosures so make a box that
you can securely place the bait and a small entry on the side. A little
talcum powder in the area will tell you if they have been there.

There is a chaining fence behind the shed in the backyard that is a
porthole for large mouse. I can identify that the rats are coming from
there because the grasses are dying from mouse foot stomps and
shades. What is the best deterrent to keep the mouse out?

Thanks
