Flour Beetle Bites and Treatment

While flour beetles do possess mouthparts, they do not usually bite humans or pets but red flour beetles can cause allergic reactions that cause wheals or raised red, itchy welts that can be mistaken for flour beetle bites.

Cleaning and sanitizing your home, regularly wiping down pantry spills and keeping the dining, food prep and eating areas clean and floors swept and vacuumed can help deter pantry pests. Regularly rotating your dried goods and storing them in airtight, glass, metal or hard plastic containers can make your home less attractive to all kinds of household pests and keep allergens out of your home.
