Cigarette Beetles: Identification and Control

Cigarette beetles (Lasioderma serricorne), also known as tobacco beetles, are a common pest found in homes, warehouses, and stores worldwide. These small beetles belong to the family Anobiidae and are notorious for infesting various stored products, including tobacco, spices, grains, dried fruits, and even books.


Identification of Cigarette Beetles

  • Size and Appearance: Adult cigarette beetles measure approximately 2-3 mm in length and have an elongated, oval-shaped body. They are reddish-brown in color and have distinct antennae with a clubbed ends.
  • Wings: Cigarette beetles possess functional wings and are capable of flight. However, they are not strong fliers and are often found crawling around infested areas.
  • Larvae: The larvae of cigarette beetles are small, white, and worm-like in appearance. They have a distinct head capsule and can be found within infested materials.

Behavior and Habits of Cigarette Beetles

  • Food Sources: Cigarette beetles primarily feed on dried plant materials, including tobacco, spices, cereals, dried fruits, and various other organic products. They also infest upholstered furniture, carpets, and even books.
  • Reproduction: Female cigarette beetles can lay up to 100 eggs during their lifetime. These eggs are often laid near suitable food sources and hatch within one to two weeks. The larvae undergo several molts before pupating and transforming into adult beetles.
  • Life Cycle: The life cycle of cigarette beetles can range from 30 to 90 days, depending on environmental conditions such as temperature and humidity. Under favorable conditions, these pests can complete multiple generations in a year.

How to Identify Cigarette Beetle Infestations

  1. Visual Inspection: Look for adult beetles crawling or flying around stored food products or infested areas. Check for small holes, webbing, or powdery residue, which may indicate the presence of cigarette beetle larvae.
  2. Sticky Traps: Place sticky traps near potential infestation sites to capture adult beetles. These traps can help monitor and confirm the presence of cigarette beetles on your property.
  3. Pheromone Traps: Utilize pheromone traps specifically designed for cigarette beetles. These traps contain synthetic sex pheromones attracting male beetles, aiding the identification and monitoring of the population.

Extermination Techniques for Cigarette Beetles

  1. Sanitation: Remove all infested materials from your premises, including affected food products, furniture, and other potential hiding places. Thoroughly clean and vacuum the infested areas to eliminate any remaining beetles, larvae, or eggs.
  2. Freezing: If possible, freeze-infested items below -18°C (-0.4°F) for at least 72 hours. This process kills all life stages of cigarette beetles, including eggs, larvae, and adults.
  3. Insecticides: To apply targeted insecticides for severe infestations, consult a professional pest control service. They can access safe and effective formulations designed specifically for cigarette beetle extermination.
