  • To get rid of these guys you have to throw out infested foodstuff and wash down the shelving and cabinets wherever they are. Start over by storing all grains (i.e. flour, sugar, cereals, etc) in airtight containers. I also go a step further and freeze all flour, sugar, and rice for 24 hours after purchase prior to emptying them into their containers. Haven’t had an infestation since adopting this practice in years!

  • We just had to get rid of a bunch of pasta wheat like oatmeal and that such. I saw the image on the Internet. How do we get rid of these bugs. Would a bug trap of some sort work. Please let me know as soon as you can thank you

    • If you have large numbers, you need to locate the stored foods that are infested and remove that food from the pantry.

  • Don’t bother trying to drown a grain beetle they can crawl out of the water.

  • My husband wrote to me today, “One of the black bugs hitched a ride to work in my lunch bag today, and I found him after he had survived 2 minutes in the microwave. I opened the door and he was walking around on the glass plate. They may be harder to get rid of than we think.”
    We are moving to a new house and hoped to leave them all behind, but I’m sure some will come with us. What can be done to really be rid of these pantry beetles? I know you don’t advise extermination, but they’re happy to eat crumbs or invisible stuff on toys. Then again, I don’t want to cover everything I own with pesticides either.

    • Not moving any stored food and keeping stored grain products for only short periods of time in the new home should help.

  • The sawtoothed grain beetle is not attracted to light and it does not fly. There is a related insect, the merchant grain beetle. The fact that the merchant grain beetle can fly is used as a way to tell them apart.

  • Hi there, I have something like this. Small, dark brown reddish oval bugs that appear on floors, walls and ceiling at the top of my stairs, bedroom and upstairs loo. They’re smooth and a single colour. They have wings but I’ve never seen them fly.
    Can you help?
    Thanks
