So your plan is to eliminate the squirrels from your property? Sorry, but the squirrels were here first. If you don't feed them, don't provide tasty treats like bulbs, and don't provide food-producing trees, like oaks, the squirrels will go away. To find food. Somewhere else.
As long as you are feeding the squirrels, whether intentionally or not, the squirrels will continue to breed at their highest rate, probably two litters of young instead of one. Try withholding all the bird food for one full year (don't worry, the birds won't starve; your neighbors will see to that) and the squirrels will relocate themselves.
I found it a bit confusing when you said you did not want to harm the squirrels, then you trapped and dumped them like they were in the Witness Protection Program leaving them to die a slow death. After that idea you had a better offer and planned to give the the trapped squirrels to the farmer so people can hunt/kill/shoot them. I'm pretty sure this will harm the squirrels.
In the past sixty-five years I only eaten one squirrel and it was delicious; I was a guest at dinner and everything on the table was legally captured, hooked, trapped, shot or grown by the host and hostess.
And in my life (up to this point) I have only had a problem with one family of squirrels; that was because they entered my house while we were doing renovations and they tried to live in the attic. Sorry guys, 'no pay - no stay'. I did not harm them, but I did give them a scare. I simply waited until they were warm and cozy and asleep for the evening in my attic, then nailed a board over their entrance hole. Once they discovered they were trapped in the attic, they wanted out, and fast. Waiting only long enough for them to get the message, I then removed the board and jumped off the ladder as they scampered away. They did not return. Period.
I happen to like squirrels and find them amusing; I allow them to live in peace where they will, as long as it is not inside my house; I don't feed them nor do anything to discourage them. I do not plant oak trees or daffodil bulbs or anything that will encourage them to come closer.
Also, I would like to say that
with your wife who is a wise and a patient woman.
