On this island we are just starting to see black and grey squirrels. They are not native to the area and may displace our indigenous ones that are only half the size and strictly forest dwellers. One story has it that some researcher imported some to experiment with and some got away. Every year I see more on my walks though none in my yard yet.
One gardening friend thinks nothing of it, the more the merrier. Soon enough she will know why they are undesirable. I have noticed one old greenhouse type structure covered in wire mesh . That looks to be the way of the future, now, against squirrels though the wire cage was meant to keep deer at bay. An expensive investment but better than losing everything.
Seems a hopeless problem for a farmer but at least shooting is possible on a farm. What other methods of control are there? Do they go for poison bait the way rats do?
