The khapra beetle (Trogoderma granarium) is considered one of the world's most destructive stored-product pests and is a federally regulated quarantine pest in the United States. It is heat-tolerant, drought-resistant, and capable of surviving without food for years in a dormant larval state — making it extraordinarily difficult to eliminate once established. Khapra beetles attack grain, flour, dried milk, dried meat, and other stored products. The larvae are covered in long, barbed hairs that can cause respiratory irritation and allergic reactions in humans. Arizona's hot, dry climate is ideal for khapra beetle survival, and the state has been the site of several interception events at ports of entry.

If you suspect a khapra beetle infestation, contact a licensed pest control professional immediately — this is not a pest for DIY treatment. Khapra beetles are regulated by the USDA and confirmed infestations may require notification of state and federal authorities. Professional treatment typically involves fumigation with methyl bromide or phosphine gas, combined with thorough cleaning and disposal of all infested products. The dormant larval stage can survive standard insecticide treatments, making fumigation the only reliable elimination method. Preventing khapra beetle introduction means inspecting all imported grain products and avoiding purchasing grain from unknown sources.

Khapra beetles are most commonly introduced through imported grain, spices, and dried goods from regions where the pest is endemic (Middle East, South Asia, Africa). Arizona homeowners who purchase imported dried goods from international markets should be particularly vigilant. If you find small, hairy larvae in grain products or notice unexplained grain damage, contact Pest Control Bros LLC immediately for a professional inspection.
