I use the white bags you get at a bakery when you buy cookies or donuts, they work great.

How is the mosquito fabric working for ya ?

my thought, is if it is too thin and stretched tight on the fruit, then, it is possible that they could sting through it.
also, it might not deter larger rodents or squirrels that might be able to claw through it ?
i have never had problems with wasps (knock on wood)
squirrels and birds are my problem.
i normally keep several trees, so if they get 1 or 2 fruit, its no big deal.
its when i only have 3 ripe ones, and they take one bite out of each that ticks me off :)

ive used paper bags before,
works good except you cant see the color of the fruit to know when its time to pick, kind of a pain, but they work.
