Scratching in the Walls This Summer? Edmonton Pest Warning Signs You Shouldn’t Ignore
Hearing scratching, rustling, or movement inside your walls during the summer can be unsettling—and for many Edmonton homeowners, it’s one of the first signs of a hidden pest infestation.
While many people associate rodents and pest problems with winter, summer is actually one of the most important times to catch infestations early. Pests become highly active in warm weather, searching for food, water, shelter, and nesting areas that can eventually turn your home into a long-term problem spot.
At We Clean Pest Control, one of the most common emergency calls during summer starts with a homeowner saying:
“We keep hearing scratching in the walls.”
If you’re hearing noises inside your home, noticing sudden pest activity, or worried something may be living in your attic or walls, this guide will help you understand:
- What causes scratching sounds in the walls
- Which summer pests are most common in Edmonton
- Warning signs of a growing infestation
- DIY prevention tips
- When it’s time to call professional pest control
Why Summer Pest Problems Are More Common Than People Think
Summer creates ideal conditions for pests in Alberta.
Warm temperatures increase:
- Pest activity
- Breeding cycles
- Nest expansion
- Food and water searches
Many pests become more aggressive or visible during the summer months, especially:
- Mice
- Rats
- Carpenter ants
- Wasps
- Spiders
Even if pests aren’t fully inside your living space yet, summer is often when they begin:
- Exploring entry points
- Nesting in walls and attics
- Establishing colonies
👉 By fall and winter, these small problems can become serious infestations.
What Does Scratching in the Walls Mean?
Scratching sounds are usually caused by pests moving through:
- Wall voids
- Ceilings
- Attics
- Basements
- Crawl spaces
The type of noise can help identify the pest.
Mice in Walls
Mice are the most common cause of scratching sounds in Edmonton homes.
Typical signs include:
- Light scratching at night
- Fast scurrying sounds
- Droppings near kitchens or storage areas
- Chewed food packaging
Mice are especially active overnight and can enter homes through openings as small as a dime. Homeowners can reduce risks by learning how to keep mice and rats out this winter.
Rats in Walls or Attics
Rats tend to make:
- Heavier scratching noises
- Thumping or gnawing sounds
Rats are more destructive than mice and can:
- Damage insulation
- Chew wiring
- Create serious contamination issues
Carpenter Ants in Walls
Carpenter ants are another major summer pest in Edmonton.
Unlike regular ants, they tunnel through wood, which can create:
- Rustling noises
- Soft clicking sounds
- Structural concerns over time
These infestations are commonly found in:
- Damp wood
- Decks
- Basements
- Window frames
Other Summer Pests
Depending on the property, scratching or movement may also involve:
- Squirrels
- Wasps inside wall voids
- Larger insects or nesting pests
Why You Should Never Ignore Scratching Sounds
Many homeowners wait too long before calling pest control because the sounds seem minor at first.
Unfortunately, pests rarely stay “small problems.”
Ignoring scratching in walls can lead to:
Rapid Infestation Growth
Rodents reproduce quickly during warm months.
Property Damage
Pests can damage:
- Drywall
- Insulation
- Wiring
- Wood framing
Health Risks
Rodents can contaminate surfaces and food sources.
Increased Costs
The longer pests remain hidden, the more extensive treatment and repairs may become.
Signs You May Have a Sudden Pest Infestation
A sudden increase in activity is often a warning sign of an established infestation.
Watch for:
- Scratching noises at night
- Droppings
- Strange odors
- Increased insect activity
- Chewed materials
- Visible nests
Summer infestations can escalate quickly because pests are actively breeding and expanding colonies. Homeowners should also understand common pest entry points and how to seal them to prevent infestations from worsening.
DIY Tips for Summer Pest Prevention
There are several things Edmonton homeowners can do to reduce pest activity during summer.
Seal Entry Points
Inspect:
- Foundation cracks
- Utility openings
- Roof vents
- Door and window gaps
Even tiny openings can allow pests inside.
Eliminate Outdoor Attractants
Keep your property maintained by:
- Trimming bushes and trees
- Removing debris piles
- Keeping firewood away from the house
Control Moisture
Many pests are attracted to damp areas.
Fix:
- Leaky pipes
- Poor drainage
- Damp basements
Store Food Properly
Rodents and insects are attracted to easy food access.
- Use sealed containers
- Clean spills quickly
- Keep garbage bins tightly closed
Why DIY Pest Control Often Fails
While DIY prevention helps, infestations hidden inside walls or attics are difficult to fully eliminate without professional treatment.
Common DIY problems include:
- Missing hidden nests
- Treating only visible pests
- Incomplete sealing of entry points
- Temporary results
👉 Many homeowners end up spending more money on repeated DIY attempts before finally calling a professional. Understanding DIY versus professional pest control can help homeowners make better long-term decisions.
When You Should Call a Professional Pest Control Company
You should contact a professional immediately if:
- Scratching sounds continue nightly
- Pest activity suddenly increases
- You see droppings or nesting materials
- DIY methods aren’t working
- You suspect rodents or carpenter ants inside the walls
These are signs that the infestation is likely established and growing.
