Hi,
If anyone is thinking of starting a bait station for the winter squirrels or even now, I've found them to have a real love for plums. There's a plum tree outside my bedroom window and considering we haven't really seen many squirrels about since we shot quite a few at the start of spring there's been a huge amount on the tree, up to 4 at once! I've had 6 in the last 2 days on it, they can't get enough of plums.
Just a tip, use plums on your bait station = almost guaranteed luck
