My son's gun club in Merced County, CA discovered a big problem. 38,000 rounds of ammo had to all get cleaned when they discovered that the foam inserts inside the individual cardboard boxes of ammo had been getting munched by ants over time. They turned the foam into little piles of powder and ant eggs. Since the insect eggs have moisture, this started corrosion on the individual cartridges. This foam is based on cellulose - a known food source for multiple insects, including ants, moths, and others. Other manufacturers use petroleum-based foam inserts that hold the individual rounds. Beware.
