These little guys are one of the more common grain pests we get calls about here in Cairns. They're most commonly found in pantry cupboards where stored grain products are kept such as cereal, pasta, flour and rice etc.
The cigarette beetle or otherwise known as the tobacco beetle, Lasioderma serricorne, is given its name as it also infests tobacco products. The beetles occur throughout the tropical and subtropical regions of the world.
The adults are small oval, globular beetles, measuring about 2 to 3.5 mm, and reddish brown in colour. They have long antennae which are waved rapidly when walking. Adults are able to fly and they often curl up and lay motionless when disturbed.
