Pest Control in Elgin | Stored Product (Updated 2025)

Management of Stored Product Pests

Stored product pests are by far the greatest menace to homes and businesses in Elgin, especially because they operate warehouses, storage spaces, and grocery stores. Infestations by such common pests as beetles, weevils, moths, and mites would most likely occur in grains, milled products, cereals, dried fruits, nuts, and any and all stored food products. Eventually, this leads to food contamination, loss in profitability, and even regulatory nuisance. The eradication and management of stored product pests largely depend on their early identification, sanitation, exclusion, and expert pest control.

Common Types of Stored Product Pests

1. Indian Meal Moth (Plodia interpunctella)

• Adult moths have reddish-brown forewings with a lower half that is coppery.
