The species composition, frequency and abundance of insect pests (Coleoptera) occurring outside a grain store were explored. Wheat bait traps were used for pest monitoring; they were changed every month from April to September. For the first time the outdoor occurrence of primary and secondary stored-product pests was documented in the Czech Republic. Seven species of Coleoptera were found outside the grain store. Pest abundance and frequency were in high correlation. The primary pest Sitophilus granarius was dominant.
