If you’re finding a bunch of uneaten seeds around your birdfeeders, weevil larvae may be eating the hearts out of sunflower seeds. While the birds will eat the worms or the bugs if they find them, they’ll kick all of the empty shells to the ground.

Prevent the problem
Not sure if weevils are the problem? Here are two signs your birdseed is infested:
Tiny holes in the seeds like those in the photo at left
Clumps of white cobwebs mixed in with the seeds
This problem gets worse the longer the seed is stored, especially in warm weather. So always store bags of seeds in a cool spot. If you feed birds in summer, store the seed in the freezer. This may not kill larvae already inside the shells, but it will keep them from eating more of the kernels.
