Boo! Halloween is here, but ghosts and goblins aren’t the only things that should send a shiver down your spine. In British Columbia, some of the scariest Halloween surprises have four legs, eight legs, or wings — and they may be looking for a warm place to hide!
As temperatures drop across the Lower Mainland, unwanted pests may seek shelter inside homes, garages, crawl spaces, attics, and wall voids. What starts as a tiny scratching sound in the middle of the night can become a much bigger problem if it’s ignored.
At Go Green Pest Control, we help homeowners take proactive steps to protect their properties from unwanted pests. This Halloween, let’s uncover the real monsters that could be lurking around your home — and learn how to keep them out.
1. Rats and Mice: The Real Halloween Nightmares
Forget haunted houses. Hearing scratching inside your walls at 2 a.m. can be frightening enough!
Rats and mice can enter through surprisingly small openings in foundations, gaps around utility lines, damaged vents, and spaces beneath doors. Once inside, they may nest in attics, crawl spaces, garages, and wall cavities.
Signs of rodent activity include:
- Droppings in cupboards, attics, garages, or crawl spaces.
- Scratching, scurrying, or gnawing sounds.
- Chewed packaging, wiring, or other materials.
- Nesting materials and unusual musty odours.
Rodents can contaminate food and surfaces, damage property, and create potential health concerns. As fall turns to winter in BC, prevention becomes especially important.
Halloween prevention tip: Seal exterior entry points with suitable rodent-resistant materials, store food in secure containers, keep garbage lids closed, and remove clutter that can provide nesting areas.
If you suspect rats or mice, Go Green Pest Control can help assess the situation and recommend an appropriate control plan.
2. Spiders: Eight-Legged House Guests
Spiders are a classic Halloween decoration — but most homeowners prefer them outside rather than in the basement or bathroom!
As the weather changes, spiders may become more noticeable indoors. Garages, basements, storage rooms, and undisturbed corners can provide shelter and access to insects they feed on.
How to make your home less attractive to spiders:
- Vacuum webs and egg sacs where safely accessible.
- Reduce clutter in basements, garages, and storage areas.
- Install or repair window screens and door sweeps.
- Reduce other insects that may provide a food source.
Most spiders encountered in BC homes are not medically significant, but unusual bites or concerns about a potentially dangerous spider should be assessed carefully.
3. Wasps and Yellowjackets: The Flying Fright
A surprise encounter with a wasp can be scarier than any Halloween prank!
Late summer and fall can bring increased encounters with yellowjackets as they search for food. Nests may be located in wall voids, roof spaces, shrubs, or underground cavities.
Keep outdoor food covered, secure garbage and compost containers, and avoid disturbing suspected nests. If you discover a nest near an entrance or high-traffic area, keep your distance and arrange for professional assessment. People with severe sting allergies should take particular care.
4. Ants and Other Tiny Invaders
Not every pest makes a dramatic entrance. Sometimes, the scariest infestation begins with a few tiny visitors.
Ants may enter in search of food and moisture, while other occasional invaders can appear around windows, foundations, and basements as seasonal conditions change.
Wipe up food spills, store sweets securely, repair moisture problems, and seal gaps around doors and windows. If pests keep returning, identifying the species and locating the source is an important step toward effective control.
5. Your Attic and Crawl Space: Where Hidden Problems Begin
If your home has an attic or crawl space, don’t let it become a real-life haunted house!
These areas are often quiet, dark, and undisturbed — making them attractive shelter for rodents and other pests. Because they’re not visited every day, early signs of activity can go unnoticed.
Watch for droppings, nesting materials, damaged insulation, gnaw marks, and unusual noises. Avoid disturbing suspected rodent nesting areas or contaminated materials without appropriate precautions.
A professional pest inspection can help identify evidence of activity, possible entry points, and practical preventative measures.
6. Five Ways to Keep the Halloween Horrors Outside
Before the trick-or-treaters arrive, take a few minutes to pest-proof your property.
- Seal entry points: Inspect foundation gaps, door sweeps, vents, and openings around pipes and cables.
- Remove food sources: Keep garbage sealed and clean up outdoor food waste.
- Reduce clutter: Store firewood, cardboard, and other materials away from your home’s exterior where practical.
- Manage moisture: Repair leaks and address standing water where possible.
- Schedule an inspection: If you notice droppings, repeated pest sightings, or scratching noises, investigate early before the problem becomes more established.
Prevention is often easier than dealing with an established pest problem.

Frequently Asked Questions About Halloween Pests
Why do rats and mice enter homes in the fall?
As temperatures fall, rodents may seek food, shelter, and nesting locations indoors. Small openings around foundations, doors, vents, and utility lines can provide access.
Are spiders more common in homes during Halloween season?
Spiders may become more noticeable in fall because of seasonal activity, mating behaviour in some species, and changes in where they are seen indoors. Their presence does not necessarily mean a home is infested.
What should I do if I hear scratching in my attic?
Look for other signs of activity from a safe distance, such as droppings or disturbed insulation. Avoid handling contaminated materials, and consider a professional inspection to identify the animal and possible entry points.
How can I prevent rodents from entering my home?
Seal suitable entry points, secure garbage and food, reduce exterior clutter, and inspect areas such as garages, attics, and crawl spaces for signs of activity.
