In the midst of your holiday preparation at your home in Des Moines, it’s easy to overlook the possibility of an uninvited guest. The kind that can spoil the perfect scene in an instant: a spider building a web in the corner of the guest room, tiny moths fluttering out of the flour meant for the pumpkin pie, or the heart-stopping sight of a mouse darting across the kitchen floor.
This blog isn’t meant to add another worry to your holiday plate. Instead, think of it as a helpful checklist from a neighbor. For over 50 years, Diam Pest Control has been a part of this community, helping families in Des Moines and Urbandale ensure their homes are perfectly prepared for the most important gatherings of the year.

The Holiday Hotspots: Where Pests Hide
A home preparing for a holiday is a dynamic environment, and this sudden burst of activity creates unique opportunities for pests. The combination of increased food storage, the opening of long-undisturbed rooms, and the general hustle and bustle can either introduce new pests or reveal ones that have been hiding all along. To prepare effectively, it helps to know exactly where to focus your attention.
These are the three main hotspots for pest activity before a big holiday gathering:
The Attic & Basement: These storage areas are where holiday preparations often begin. As you pull down boxes of cherished fall decorations, platters, or extra folding chairs, you might be disturbing more than just dust. Rodents and spiders often use storage boxes as shelter. The increased foot traffic and open doors can give a curious mouse the perfect opportunity to leave the basement and start exploring the kitchen.
The Pantry: The heart of the Thanksgiving feast is also a major target for stored-product pests like the Indian Meal Moth. As you stock up on new baking supplies like flour, cornmeal, cake mixes, and spices, you can unknowingly introduce these pests into your home. They thrive in stored grains and can quickly spread from one container to another, contaminating your ingredients.
The Guest Room: That spare bedroom that sits quiet for most of the year can be a haven for pests that prefer undisturbed spaces. Spiders love to build their webs in quiet corners, while silverfish and dust mites can thrive in closets and under beds. When you open the room and start preparing it for guests, you’re often the first to disturb their peace, making them suddenly visible.

The Pre-Thanksgiving Pest-Free Checklist
Feeling in control is the key to a stress-free holiday. This step-by-step checklist is designed to be a simple, manageable part of your Thanksgiving preparations, allowing you to systematically secure your home and put your mind at ease.
Step 1: The Pantry Purge & Protect
Before you do your big Thanksgiving grocery shop, give your pantry a thorough inspection. This single step can prevent a baking disaster.
Invest in Airtight Containers: This is the most crucial step. When you bring your new baking supplies home, immediately transfer them from their paper or plastic bags into airtight glass or hard plastic containers. This quarantines your ingredients, so even if one item was contaminated, the pests cannot spread.
Inspect Old Supplies: Go through any open bags of flour, sugar, rice, cornmeal, and other grains. Look for small webs, clumps, or the pests themselves. Check the dates on old spices and mixes. When in doubt, throw it out.
Wipe Down Shelves: Remove everything from the shelves and vacuum them thoroughly, paying special attention to corners and cracks. Then, wipe them down with warm, soapy water.
Step 2: The Guest Room Refresh
Ensure your guests have a comfortable, pest-free stay by giving their room a deep clean a week or so before they arrive.
Check the Windows: Wipe down the window sills and check the screens for any tears. This is a common spot to find overwintering insects like boxelder bugs or spiders trying to stay warm.
Vacuum with a Vengeance: Use your vacuum’s crevice tool to thoroughly clean along all baseboards, in the corners of the room and closet, and behind the headboard and other furniture.
Wash All Linens: Strip the bed and wash all linens, including the mattress pad and any decorative pillows, in hot water to eliminate dust mites and any other hidden pests.

Step 3: The Decoration De-Bug
Those beautiful fall decorations can unfortunately serve as a Trojan horse for pests. Inspect them carefully before they enter your main living spaces.
- Unpack Outside: Take boxes of decorations from the attic or garage and unpack them outside or on an enclosed porch first. This prevents any hitchhiking spiders or insects from being released directly into your home.
- Inspect Natural Items: Carefully check any natural decorations like dried wreaths, cornucopias, or decorative gourds. Look for spider webs, egg sacs, or other signs of pest activity before bringing them inside.
Step 4: The Kitchen Lockdown
During the beautiful chaos of cooking, your kitchen becomes highly attractive to pests. A few simple habits can keep it secure.
- Clean Spills Immediately: With so many sweet and savory ingredients in use, spills are inevitable. Wiping them up right away removes a powerful food source for pests like ants and mice.
- Take Out the Trash Nightly: Your trash can will be full of rich, enticing food scraps. Be sure to empty it into a secure outdoor bin every single night leading up to Thanksgiving.
- Check Under the Sink: Increased use of the sink and dishwasher can sometimes cause small leaks to appear. Take a quick look under the sink to ensure everything is dry, as moisture is a major attractant for many pests.
Step 5: The Final Peace of Mind Perimeter
Following this checklist will make the inside of your home an unwelcome place for pests. The final step of holiday pest control in Des Moines, is to ensure nothing new can crash the party from the outside. A professional exterior treatment provides a preventative barrier around your home’s foundation. This service stops pests in their tracks before they can find a way inside while you’re busy cooking, celebrating, and enjoying your family. It’s the final detail that provides true peace of mind.

A Hyper-Local Holiday Report: Iowa’s Unique Thanksgiving Pests
Every region has its own pest pressures, and preparing for a holiday in Central Iowa means understanding our specific seasonal challenges.
- Mice and the First Hard Freeze: The timing of Thanksgiving in late November often coincides perfectly with Iowa’s first sustained period of below-freezing temperatures. This is a critical survival trigger for mice. The cold snap creates a massive surge of rodents looking for warmth and shelter, making homes in Urbandale and the surrounding metro, especially those near open fields or new developments, prime targets for invasion.
- Spiders in the Basement: As you head to the basement to retrieve folding chairs, card tables, or your grandmother’s favorite serving platter, you might be surprised by the number of cobwebs and spiders you encounter. Common wolf spiders and cellar spiders love the quiet, dark corners of a basement. They’ve likely been there all year, but the sudden activity of holiday prep disturbs their hiding spots and brings them out into the open.
- Pantry Pests from Local Sources: While pantry pests can come from anywhere, it’s wise to be vigilant. These pests can occasionally hitch a ride from large distribution centers, grain mills, or even the grocery store itself. This is why the “Pantry Purge & Protect” step is more than just a cleaning task; it’s a smart, preventative habit for anyone planning their holiday pest control in Des Moines.
