While named for their appearance in the larval stage, yellow mealworm adults look like typical beetles. They are dark in colour and about 12 to 13 mm long. Mealworms usually feed on damp, decomposing, or moldy items, including leaves, dead insects, moist grains in the process of decaying, and animal waste. They normally live in dark, cool, and moist locations where suitable food is present. Infestations of this insect are rare in homes, but if you find yourself in need of yellow mealworm control in Calgary, don’t hesitate to call us.
