Do weevils spread fast?

Yes, weevils spread quickly, especially in pantries, due to their rapid reproduction (females laying hundreds of eggs in food like grains and cereals) and ability to infest sealed packages, leading to widespread contamination within stored food products and homes. While some types, like the granary weevil, can't fly but will travel, others, like the maize weevil, can fly significant distances to find new food sources, accelerating their spread.
