Combating bean beetles

Environmentally friendly products and natural solutions for home pest control.

1. General information about bean beetles

The bean beetle (Acanthoscelides obtectus) is one of the most common pests in kitchens, pantries, and storage rooms. It primarily attacks dried beans, peas, and other legumes . The females lay their eggs directly on the beans, from which small larvae hatch after a short time. These burrow into the bean and feed there until they pupate.

The result: Beans are hollowed out from the inside, lose weight and nutrients, and are no longer edible. A severe infestation can render entire supplies unusable and quickly spreads to other foods.

2. Detect bean beetle infestation – typical signs

You can recognize an infestation with bean beetles by typical signs:

  • Round holes in beans or peas caused by hatching beetles
  • Hollow or crumbling legumes that have been eaten from the inside
  • Small beetles (2–5 mm in size) , brown to black with conspicuous spots
  • Larvae or pupae inside the bean
  • Sudden mass infestation in storage containers or pantries

Anyone who notices these signs should act immediately, as bean beetles multiply quickly in supplies.

3. Preventing bean beetles – tips for the kitchen and pantry

To prevent bean beetles from spreading in the house , the following preventive measures are important:

  • Store beans and pulses airtight – preferably in screw-top jars or tightly sealable containers
  • Store supplies in a cool, dry place , as bean beetles love warmth
  • Freeze newly purchased beans (at least 48 hours) to kill any eggs or larvae
  • Regularly check supplies and spices for signs of feeding or beetles
  • Use up old stocks in a timely manner and do not store them for too long
