Keep storage shelves free from grease or cheese crumbs and keep meat and cheese covered in a cool place. If infestation occurs, remove food, thoroughly clean surfaces and spray or dust with a product labelled for fly control.
For a heavy Cheese Skipper infestation, we would recommend you contact professional pest control company, preferably a member of the IPCA to administer a professional treatment to solve the problem. A trained professional will have the technical knowledge and access to a range of professional use products and equipment which are not available to the public.
