Why do weevils keep coming back?

Weevils keep coming back because they are incredibly persistent, often hitchhiking in on infested food (eggs laid before packaging), hiding in unseen pantry cracks, and reproducing rapidly in stored grains, meaning a few survivors or newly hatched adults quickly restart the cycle, especially in warm, moist conditions. Complete eradication requires meticulous cleaning, discarding all infested food, and storing new items in airtight containers to stop the hidden eggs and adults from hatching and multiplying, say the Rutgers Cooperative Extension and other experts.
