Red Flour Beetle

(Tribolium castaneum)

Description: Reddish-brown body 1/8” long; last three segments of antennae as distinct club.

Life Cycle: Egg to adult within 30 days; adults can live up to 18 months

Feeding Habits: Generally classified as a scavenger, immature stages feed on broken or damaged grains. A common pest in mills and warehouses that store milled/bagged grain products.

Signs of Infestation: Presence of adult beetles cause food to have pungent odor, foul taste and potentially a pink coloration.

Control Tips: Clean and spray grain bins with Gravista® Insecticide prior to grain storage. For treatments of six months or longer, inspect and treat incoming grain with Gravista® Insecticide; monitor grain throughout storage period. To bring a boost to short-term grain storage of six months or less, and for rescue treatments, treat with Centynal™ Synergized Insecticide.

Application Tips: When treating flowing grain on belts or at transitions, 2 or more nozzles are recommended; during auger or conveyor cup application, fewer nozzles may be used; position nozzles for full coverage of grain stream; avoid spraying onto sides of auger boots. Calibrate protectant flow rate and check often to help ensure proper application. Use automated switches to turn chemical pumps on when there is grain in the system and turn off when no grain is present.
