Flour beetle infestation

My daughter has moved into a newer home ( 3 yrs old) and has discovered the red flour beetle in her pantry and upstairs on the bedroom level – what is the best method to get rid of them? she has put all cereals and flour into sealed containers.

Pantry pest beetles lay eggs close to a food source. In a home they may lay them on the rims of dry food containers where they may fall into the food. It would probably be wise to dispose of all dry stored food and thoroughly clean the containers. The cupboards must also be cleaned paying careful attention to any cracks or gaps around the edge of shelves. You may have to spray an insecticide then after a day or two wipe away any residual pesticide before putting the food containers back.
