"Castanheeira said she bought the candy at a Shell gas station. She said all the candy is off the shelves because she went back and bought it all to see if it was infested."
What? That makes no sense.
I did find this:
RF Insect infestation / Diseases
Cocoa moths (also known in the US as almond moths) and meal moths may attack chocolate. Nut chocolate may also suffer attack from flour beetles and dried fruit moths. Occasionally, maggots are found in chocolate, particularly if it contains nuts or fruit.

Yes, it is common for meal moths to infest chocolates or nut bearing candies. That is one of the reasons there is a shelf life on packages.
Years ago I ran a small drug store and the chocolates in the candy aisle bacame infested with meal moth. When you shop and see those little moths flitting around a store...there's an infestation somewhere. After the discovery and initial disposal of all the candy(15ft. section) I would go over and randomly open candy bars to check the candy. There are still some candies I won't purchase because they are prone to being infested.
Maybe she bought it to prevent the hoax from being discovered.
