It’s the groundhogs that have done us in. We can deal with most of the other stuff - lose half our garden perhaps. But ONE ground hog can (and does) destroy a garden (30x45) in just two evenings.
We had it solved for awhile, but in the past two years our fence “solutions” took some damage - and if there is ANY breach at all, those little bas***** will find it fast.
At least the feral cats ate all the rabbits and most of the chipmonks. The deer we still have fenced out - for now.
Do you have any streams near you that you can get free water from?
I had a problem with raccoons one year,I ran a single electric fence wire about 4 inches off the ground on the perimeter of the garden.That kept them out.Should work on woodchucks too,I just shoot them here.
LOL! We have had a lot of chipmunks in years past, and in past several months we have also noticed a pride of feral cats in and around our back yard. The chipmunks are not as much a problem now, which is a relief! They had done a lot of damage to our garage roof a number of months ago.
