no, once they are off the tree that is it....

I am not a fig Expert but my understanding Figs need suns to ripen. As for your Squirrel problem I have the same thing but I think I solve it. I bought a pellet Gun it shoots BB too. What I love about this Gun is that you have to cock it. To Kill or injure an animal you have to cock it 10-12 times. But I have no intension of killing or injuring any animal. I cock it 3 times and I just give him a sting in the But. He never come back. My Girl friend walked me and told me there is a deer nibbling on my apricot trees I cocked the gun 4 times and I gave her a shot in the But she jumped over the fence and never came back. The Squirrels don't eat fruit but they destroy them by cutting a hole in every one. Now in Winter I buy squirrel food and feed them. I told them I have the Olive branch in one hand and the gun in the other hand get away from my trees we stay friends. I wish they understand.

Haha! You are wonderful, FP!
