Maize Weevil Identification in South Florida
Maize weevils are destructive stored-food pests commonly found throughout South Florida, especially in grain storage areas, kitchens, food warehouses, pantries, agricultural facilities, and homes storing dry food products. These beetles infest corn, rice, grains, seeds, cereals, and other pantry products where larvae develop hidden inside food kernels. Maize weevils closely resemble rice weevils and are small reddish-brown beetles with elongated snouts and lighter-colored spots on their wing covers. The scientific name for the maize weevil is Sitophilus zeamais, and they are also commonly referred to as corn weevils or grain weevils.
What Are Maize Weevils?
Maize weevils are stored-product beetles that infest grains and dry foods by laying eggs directly inside kernels and seeds.
Unlike external-feeding pantry pests, maize weevil larvae develop entirely inside food products before emerging as adults.
These pests commonly spread through contaminated food packaging and improperly stored grain products.
How to Identify Maize Weevils
Common identifying characteristics include:
- Small reddish-brown beetle
- Long narrow snout
- Four lighter spots on wing covers
- Crawling insects in pantry foods
- Infestation inside grains and corn
- Activity around dry food storage
Maize weevils are capable of flight and may spread quickly between storage areas.
