Busy families know the joy of a clean, organized kitchen. But that joy can turn to frustration if bugs invade. Even the tidiest kitchens can fall victim to unwanted insects. Preventing bugs is essential. Taking simple precautions in your cupboards and pantry can make it harder for bugs to find a place to set up camp. So read on for some tips on how to keep your kitchen pest-free!

🚫 Don’t Invite Bugs In

Start with what you bring into the house. Inspect your groceries at the store. Look at wax and plastic wrap food items for indications of bugs. Check cardboard boxes, laundry, books, and used furniture or appliances coming into the home for signs of infestation.

Keep the kitchen clean:

Keep dishes, stove top, and counters washed after every use.
Dump trash frequently.
Rinse out food containers and bottles before putting them in the trash.
Clean up spills promptly.
Don’t leave food out.
Wash or replace sponges and dishrags often.
Keep the toaster and other appliances free from crumbs and spills.
Clean appliances’ motor housing frequently, as this is a favored area of pests.
Move and clean under appliances.
Keep food in containers and wipe up food spills in cupboards promptly.
Keep pet bowls clean, and don’t leave food out overnight.
Use a trash liner in your garbage cans.
Periodically pour diluted bleach down the sink or use a microbial.

food containers that prevent bugs — Use screwed-on or snap-on lids to store food.

🛡️ Preventing Bugs Starts With Food Storage

Move foods not in screw-type jars or cans into containers with screw tops, snap-on lid plastic containers, or food-grade plastic bags with zip-lock seals. Cardboard, paper, plastic wrap, or plastic bag food containers allow for the invasion of pests.

🔍 Look For Any Openings In The House

Preventing bugs requires you to install door sweeps and repair window screens. Check around pipes where they enter the walls. Fill any gaps with silicone or with steel wool. Check for cracks along baseboards and around the outside of window frames. Check door frames, furnace flues, electrical outlets, and vents. Seal any gaps.

Repair any holes in walls and ceilings. Install screens over vents, floor drains, and ducts. And keep seldom-used drains plugged. Install foam strips or spring-loaded strips around windows and doors.

🏡 Check Outside Of House

Check outside the house and remove wood piles and debris near the foundation. Mulch should be kept 3 to 4 feet from the foundation.

Seal openings around windows, door frames, and between the foundation and brick or siding. Check the corners of the house and around pipes, flues, and vents. Not only will you eliminate openings for pests, but you will seal routes for cold air to enter the house.

You could also seal all crevices in your cupboards, eliminating hiding places. Remember to leave some room for the house to breathe.

💡 Quick Tip: Regularly inspect and maintain these seals and screens to keep bugs at bay.

Preventing bugs in the kitchen takes some work, but it is doable.

How Can I Tell If My Cupboard Has A Bug Problem?

There are a few telltale signs that your kitchen cupboard may be infested with bugs. First, look for small, dark spots where the bugs might congregate inside the cabinet.
