Facts about Grain Beetles

  • Grain beetles feed on grains and flour dusts.
  • They lay eggs on cereal products, dry pet foods and other dry goods.
  • They are good at getting into sealed packaging, and will turn products an off colour with an odd odour.


How to Make Your Home a Grain Beetle-Free Zone

  • Minimize food particle sources: vacuuming cupboards to clean off food particles will help ensure grain beetles do not return.
  • Discard any contaminated sources: though they are sometimes small and hard to spot, if one bag of items is found with a beetle in it, odds are the others have an egg or beetle as well.
  • Keep cereal items in well-sealed containers: green beetles can squeeze themselves into almost any nook and cranny. Twist-tied bags and open cereal boxes are possible targets.
