Use trap data to determine when, where to treat for SPP

Anna Hansen, Technical Support Specialist, MGK

From homes to warehouses, stored product pests (SPP) are widespread nuisances that can cause significant damage to the products they infest. Control involves eliminating infested material. Proper identification and knowledge of the SPP species will help you find and eliminate infestations more efficiently. One would not search for clothes moths (Tineola bisselliella) in paprika, for example. And sawtoothed grain beetles (Oryzaephilus surinamensis) are more likely to be found in pancake mix than kidney beans, as they cannot break open whole grains. Trap catch data informs when and where treatment is needed.

Fogging and ultra low-volume (ULV) applications can help knock down populations while searching for infested material. Always properly calibrate equipment before treating. The small particle size of fogging and ULV applications deliver active ingredients in areas where achieving good coverage is essential. Choose an oil- or water-based formulation as needed, and consider including an insect growth regulator (IGR) for additional control. While sanitation is critical for success, these applications are a useful tool.
