Black beetles belong to the insect family and are found almost everywhere in the world with many different species. It often happens that small species of bugs settle in the house and apartment. Although these are mostly completely harmless, they can quickly become a nuisance. One of the main causes of a beetle infestation is poor hygiene in the household. The animals are magically attracted to special open supplies.

countermeasures and preventive measures

Certain local conditions support the appearance of the vermin, including well-heated living spaces, always bulging pantry cupboards and dark places behind permanently installed built-in cupboards. Black beetles are lured into the house or apartment through gaps in the floor, cracks between the windows and many hiding places in the brickwork. In addition, the introduction often takes place with products that are already infested, so these should be checked for beetle infestation before putting them away.

To prevent a beetle infestation from becoming a plague, simple protective measures usually help. In order to prevent an infestation from the outset, foods that attract black beetles should therefore not be stored openly.

  • Periodically check possible locations for infestation
  • Clean the kitchen and pantry regularly
  • Also drawers and storage cupboards for food
  • Always keep bread baskets and other utensils clean and free of leftovers
  • Clean the vacuum cleaner regularly
  • If there are leftovers, vermin like to settle there
  • Store food in tightly sealed containers and cans
  • If you are unsure, put food in the freezer for 3 days as a prophylactic
  • Set sticky traps to detect infestation
  • Use vermin sprays if the infestation is severe
  • In the extreme case of a beetle plague, only a specialist can help
