Bean Weevil Infestations
Infestations may be difficult to detect in homes, until you find the young adults flying around your home, gathered by the hundreds on windowsills or crawling on your walls.
A likely place to determine the source and growth potential for a bean weevil infestation lies in stored whole beans in your pantry. Some bean weevils not only infest stored and live beans, but also popcorn kernels, garden seeds, dried seed, decorative items, Indian corn, and “bean bags”--if someone has a true “bean bag” anymore, most are made of synthetic materials now. Female beetles deposit up to 100 individually fertilized eggs on stored beans by gluing the eggs to the surfaces of beans.
When bean weevil eggs hatch, the white, wrinkled grub-like larval bean weevils eat their way into the beans where they hatch. As the larvae mature and pupate into adults, they emerge through exit holes they make in the beans they infest, to later return to their feeding areas. Bean weevil-infested beans develop a whitish hue due to the presence of bean weevil waste that replaces the contents of the bean inside bean shells.
