Before Guests Arrive: A 7-Day Checklist
- Inspect groceries. Check packaging for holes or insects before buying bulk or dry goods.
- Seal gaps. Caulk cracks around doors, windows and pipes; repair torn screens.
- Deep-clean the kitchen. Wipe under appliances, empty crumb trays and sweep behind the stove.
- Clean bins and take the trash out of the house (not into the garage).
- Move firewood and compost away from the house.
- Clear the fruit bowl and recycling that holds sticky bottles.
- Stock airtight containers (glass or hard plastic with sealing lids) for leftovers.
If you want to add a touch of elegance to your kitchen clean-up routine, consider using sustainable cotton kitchen towels from All Cotton and Linen. They’re perfect for wiping down counters and are eco-friendly too!
While You Serve: Protect the Table
Buffet and dining-table tactics
Serve in batches. Keep extra dishes in the oven or fridge and refill small amounts so food isn't sitting out.
Cover between servings. Use lids, mesh food covers or a clean kitchen towel over bowls for short breaks.
Use a small fan near the buffet. Flies are weak flyers, and moving air makes it harder for them to land (a common practical tip).
Keep a damp cloth or napkin handy to wipe spills at once. Cotton kitchen towels work well for quick wipes.
Watch the clock. Start a timer when food comes out; at two hours, refrigerate or discard.
Drinks and desserts
Sweet drinks, wine and beer attract fruit flies, so use cups with lids or cover pitchers. Put desserts out when it's time to eat, not earlier.
Use Natural Pest Repellents
If you prefer a DIY approach, there are several natural remedies to deter pests. Rodents and insects are masters of sneaking into homes through the tiniest cracks. Essential oils like peppermint, eucalyptus, and citrus can repel ants, spiders, and even mice. “I always spray a mixture of peppermint oil and water around windows and doors,” says Leah Green, a holistic home specialist. “It smells great and keeps the bugs away.”
Here’s a simple recipe:
- Mix 10 drops of peppermint essential oil with one cup of water.
- Pour into a spray bottle and apply around entry points.
After the Meal: Leftovers, Trash and Linens
Refrigerate within two hours. Divide large portions into shallow containers so they cool faster.
Seal tightly. Use glass or hard-plastic containers; paper bags, foil lids and cardboard let pests in.
Take the trash out and replace the liner; wipe the bin rim.
Wash dishes promptly and wipe counters and the stovetop.
Sweep and vacuum under the table and around chairs.
Launder tablecloths and napkins soon. Food and sugary spills left on fabric can attract ants and fruit flies. Rinse stains with cold water first, then wash per the care label; see our linen care guide.
Sending your guests home with leftovers is a great way to clear your kitchen of extra food that could attract pests,” recommends nutritionist Sara Evans. This also gives you the perfect excuse to invest in some stylish table linens and sustainable grocery bags from All Cotton and Linen.
Hosting Thanksgiving Outdoors
Outdoor meals add wasps and flies. Keep food covered until serving, cover cups and sweet drinks, wipe the table often and use a heavier tablecloth with clips or weights on windy days. Set a trash can with a tight lid away from the dining area. See our full guide to hosting Thanksgiving outdoors.
What Not to Do
Don't spray insecticide on or near food, plates or the dining table.
Don't leave leftovers on the counter overnight.
Don't store leftovers in paper or cardboard.
Don't ignore small signs. Droppings, gnaw marks or repeated sightings mean it's time for expert help.

When to Call a Professional
If you see mouse droppings, gnaw marks, repeated roach sightings or an ant trail you can't clear, contact a licensed pest-control professional. All Cotton and Linen isn't a pest-control company; this guide covers everyday prevention and food handling.” Pest control professionals can identify and seal off entry points, treat for existing infestations, and apply preventative treatments to ensure your home remains pest-free.
Conclusion: Clean, Covered and Chilled
Keeping pests away from Thanksgiving food comes down to three habits: keep food covered, clean as you go, and refrigerate leftovers in sealed containers within two hours. Add a quick home check before guests arrive and a prompt cleanup afterward, including laundering tablecloths and napkins, and you protect both your meal and your guests.
If you spot droppings, gnaw marks or repeated sightings, call a licensed pest professional rather than spraying near food. For more hosting help, read our guides to hosting Thanksgiving outdoors and caring for linen.
