What Lawrence-area families should know when students return from dorms and apartments
When college students come home—whether for a weekend, a holiday break, or summer vacation—parents are usually prepared for laundry, backpacks, and a sudden disappearance of all food in the house. What families aren’t always prepared for, however, are the pests that can hitchhike their way home from dorms, apartments, or student housing.
Dorm environments are almost perfect breeding grounds for certain pests: shared spaces, constant foot traffic, food left out, clutter, secondhand furniture, and close living quarters. And because students are constantly on the move, these pests can easily end up traveling with them.
Here are the most common ways college students accidentally bring pests home—and how to prevent it.
1. Pests Hidden in Luggage and Backpacks
Dorms and small apartments typically have limited storage, meaning bags often end up on the floor—exactly where pests like to roam.
Common hitchhikers:
- Bed bugs
- Cockroaches
- Fleas (especially in pet-friendly housing)
- Spiders
How it happens:
Bags left under beds, on carpets, or near shared lounges can pick up hitchhiking insects. Bed bugs especially latch onto seams and pockets.
Prevention tips:
- Keep luggage off dorm floors—use shelves or hard surfaces.
- When returning home, place bags in the garage or laundry room first.
- Wash all clothes (even clean ones) on high heat.
- Vacuum inside luggage before storing it away.
2. Secondhand Furniture Is a Major Pest Highway
College students love Facebook Marketplace and thrift shops—but used furniture is one of the top sources of bed bugs, roaches, and even rodents.
High-risk items include:
- Couches and futons
- Mattresses and box springs (never recommended used)
- Desks and dressers with drawers
- Area rugs and upholstered chairs
Why the risk is high:
Student housing flips tenants constantly, and many offloading furniture don’t know it’s infested.
Prevention tips:
- Avoid used mattresses or upholstered items altogether.
- Inspect furniture outdoors before bringing it in.
- Check seams, crevices, and screw holes with a flashlight.
- Consider a quick pest-control inspection for suspicious items.
3. Food Habits That Invite Pests
Let’s be honest—many students develop “creative” food storage habits in college.
Which means they often bring home:
- Half-opened cereal boxes
- Gummy snack bags
- Crumbs in backpacks
- Ramen stashes
- Trail mix bags shoved in drawers
- Drink containers in personal trash cans
These items attract:
- Ants
- Pantry pests
- Roaches
- Mice
Prevention tips:
- Toss open or half-opened food before your student returns.
- Check backpacks, tote bags, and desk drawers for old snacks.
- Clean out mini-fridges thoroughly.
4. Clothing and Bedding That Harbor Pests
Shared laundry rooms and communal housing increase pest exposure.
Pests that hide in fabric:
- Bed bugs
- Lice
- Fleas
- Carpet beetles
Risk factors include:
- Clothes left on dorm floors
- Beds without protective mattress encasements
- Shared or borrowed blankets
- Dirty hampers left too long
Prevention tips:
- Always wash bedding right when students get home.
- Use proper heat settings—cold water won’t kill pests.
- Consider mattress encasements in both dorms and home bedrooms.
5. Electronics and Small Appliances (Yes, Really!)
Small dark spaces inside electronics create perfect hiding spots.
Items that commonly carry pests:
- Gaming consoles
- PC towers
- Mini-fridges
- Microwaves
- Toasters
- Coffee makers
Roaches in particular love warm electronics.
Prevention tips:
- Inspect and gently shake out electronics outdoors.
- Check vents for signs of pests.
- Clean mini-fridges and microwaves thoroughly before moving them.
6. Pets in Student Housing
Even if your student doesn’t have a pet, their roommate or neighbor might.
Pests spread easily in pet-friendly complexes, including:
- Fleas
- Ticks
- Mites
- Ants attracted to pet food
Prevention tips:
- Encourage students not to store pet food in their rooms.
- Have them wash pet bedding before coming home.
- Treat pets for fleas and ticks year-round.
7. Roommates’ Habits Become Your Problem
Your student could be spotless—but all it takes is one messy roommate.
Common roommate-related pest issues:
- Old food under beds
- Damp towels left on floors
- Trash piling up
- Clutter that allows pests to hide
- Shared vacuum cleaners spreading pests between rooms
What families can do:
Encourage your student to:
- Keep personal belongings off the floor
- Use sealed plastic bins instead of cardboard
- Regularly empty their own trash, even if roommates don’t
How to Check for Pests When Your Student Arrives Home
Do a quick, 5-minute check:
Inspect:
- Luggage (especially seams)
- Backpacks
- Laundry bags
- Electronics
- Any furniture being moved in
- Outer pockets of duffel bags
- Shoes and under-bed storage
Clean:
- Wash all clothing and bedding on high heat
- Vacuum luggage thoroughly
- Store items in plastic bins temporarily
If anything seems suspicious—dark spots, shed skins, unusual odors, bites—it’s best to act fast.
When to Call a Professional
If you notice:
- Unexplained bites
- Little dark spots on bedding
- Bugs crawling out of backpacks or desks
- Musty “bed bug” smells
- Roach activity in warm electronics
- Ants showing up suddenly in one bedroom
- Fleas despite not having pets
