how to get rid of raccoon problems??

Truthfully, in the long term, the raccoons are actually SAVING your garden as those "grubs" you have identified as their target will continue to multiply anf destroy the roots of everything.

Nematodes are the most often used solution, and is permie friendly, BUT must be pre-ordered in most places and can only be applied at certain times of the year.

I "heard" of a granular product this year at the garden center, but have no info on how successful it is, nor it's name OR what it is.

Locally, I instruct those with this issue to dig a soil sample WITH the grubs, and have their local nursery identify the grubs nd have them advise on the appropriate solution.

The only other option is to run a hot line (electric fencing) or create an unclimbable fence out of something like metal roofing panels. As you have learned, chainlink and chicken wire is nothing but a ladder for raccoons.

Keep your eyes peeled for alternative access routes such as trees, sheds, vehicles and the like that could allow the to circumvent your efforts.

Livestock guardian dogs will protect anything their person cares about.

Bonnie, is there a particular brand or specification of BB gun that you'd recommend?  I know practically nothing about using a BB gun.

2 sure-fire fixes:
  I. Put a spoonful of cayenne in a balloon and blow it up. Tie a knot and thumb tack it to a fence. Then rub the balloon with some bacon fat.
This works on ANY carnivore, from cats to bears. They take a bite, get a bang and a facefull of red pepper. They won't come back.
 2. There is a little trap that snares coons by the wrist. It doesn't catch any other animal. Coons have a paw that works like a hand, and they have to lift a trigger in the trap.
The downside is there isn't a safe way to release the critter. You have to kill them.
