The Rat And Mouse Situation in Vancouver

The city of Vancouver has seen concerning levels of rat activity in recent years. According to pest control companies, requests for rodent control services have been steadily climbing over the past several summers. Vancouver now ranks as the second rattiest city in all of Canada, with Toronto taking the top spot.

Within Vancouver itself, downtown and the Richmond area tend to have the highest volumes of rat infestations. Back alleys, green spaces, and commercial dumpsters provide ideal breeding grounds. Videos surfacing online show alleyways teeming with over a dozen rats at once.

The mild coastal climate of Vancouver allows rats to remain active year-round. However, the coolest months of November through February see lower reproductive rates before numbers boom again in spring and peak in late summer.

Why Rat Control in Vancouver is Essential

Effective rat management is crucial in Vancouver to protect public health and safety. Rats pose a serious disease risk, capable of transmitting dangerous illnesses like hantavirus, leptospirosis, and salmonella to humans through their urine, droppings, bites, and contaminated surfaces. 

Rat infestations must be promptly eliminated to prevent wider community spread of these illnesses. Beyond disease, rats also inflict costly property damage by gnawing through building materials, wires, and pipes. Their burrowing can undermine structural foundations as well. Investing in proactive rat-proofing provides a vital shield against these health, safety, and economic threats rats represent to Vancouver residents and businesses. Diligent prevention and control measures are key to keeping our city livable and prosperous.

Why Rats Invade Our Homes

Rats are resourceful survivors always on the hunt for their basic needs – food, water, and shelter. Unfortunately, our homes often provide ideal conditions attracting rats inside1.

Several factors draw rats to residential properties including:

Access to Food Sources: Rats can smell food odors from great distances. Any unsecured human or pet food inside a home will quickly catch their attention. Garbage and compost bins are also major food attractions if not properly contained. 

Available Water

Leaky pipes, pet bowls, birdbaths, and irrigation provide ready water sources rats need to survive. They can even swim through drains and toilets into homes.

Shelter

Rats seek out protected spaces to build nests and get out of the elements. Clutter like piles of stored items and junk give them ample hiding spots.

Warmth

Particularly in the winter months, rats are drawn to the security and coziness of interior spaces. Heat is retained in wall voids, basements, and attics.

Entry Points

Rats can easily enter and escape a property through any open cracks, gaps, or holes on the outside or inside.

Keeping Rats from Getting Inside

Focus on eliminating food attractants, repairing plumbing leaks, caulking all potential entryways, and organizing clutter inside and outside the house to discourage rats. Additionally useful for removing existing rat tenants are traps. But in the end, keeping a property completely devoid of the necessities for rats to live and grow is the key to keeping them out. You can keep rats out of your house and safeguard it if you are persistent and watchful.

Rat-proofing Early: Protecting Against Rats in the Winter

Rats in Vancouver seek to the warmth and cover of interior places when the temperature drops1. Rats can find refuge in crawlspaces, garages, attics, and basements from the severe winter weather. Your house becomes a prime target for rat invasion if it is not properly sealed.

Fall and early winter is the most crucial time to inspect and rodent-proof your home before cold weather drives rats inside. Be sure to seal any possible entry points including holes, pipe penetrations, cracks, utility lines, vents, doors, and windows using copper mesh, concrete, steel wool, caulk and weatherstripping. Pay special attention to vulnerable attic and basement access.

Trimming back vegetation touching exterior walls also helps limit sheltered paths rats use. Installing door sweeps, fixing gaps in siding or foundations, and sealing trash cans all reduce winter shelter options for rats outside. Maintaining tidy outdoor spaces with no clutter or debris piles further diminishes areas where rats can nest undisturbed.

While rats pose year-round threats, their search for warmth as temperatures drop makes comprehensive rodent-proofing vital for protecting Vancouver homes during theduring winter months. Don’t let your home become a refuge for rats – take action to fortify your property against these destructive pests.

Health Risks from Rodents

Beyond causing property damage, rodents also carry diseases transmissible to humans,humans including:

Hantavirus

Spread through breathing in dust contaminated by infected rodent urine, saliva, or droppings. Flu-like Hantavirus Pulmonary Syndrome starts 1-5 weeks later and carries a 35% mortality rate. AlwaysAlways Always wear PPE when cleaning rodent infestations.

Leptospirosis

Caused by the spiral-shaped Leptospira bacteria shed in rodent urine and transmitted through mucous membranes, eyes, cuts, ingestion, and contaminated water. Its flu-like symptoms can advance to meningitis, liver/kidney failure, internal bleeding, and respiratory distress.

Rat-bite Fever

From infected rodent bites or scratches breaking the skin. Begins 3-10 days later with fever, vomiting, headaches, rash and muscle pain. Can progress to joint, heart, brain, kidney infections if untreated.

Salmonella

Rodent droppings and nesting materials frequently contain Salmonella bacteria causing diarrhea, fever, and abdominal cramps starting 12-72 hours after exposure.

Rodent Allergens

Proteins in rodent urine, saliva, and shed skin can trigger allergic reactions and worsen asthma in sensitive individuals.

Due to these serious health risks, it is critical to safely eliminate rodent infestations and prevent new ones from developing. Protect yourself and your family by properly rodent-proofing your Vancouver home.

Signs of Rodents and Potential Entry Points

The first step is conducting a thorough rodent inspection of your home’s interior and exterior. Look for evidence of current or past rodent activity including:

• Rodent droppings – Droppings are one of the easiest signs to spot. Mouse droppings are about the size of a grain of rice while rat droppings are larger, the size of an almond. Be sure to wear a mask when cleaning them up to avoid hantavirus transmission.
  
• Gnaw marks – Look along baseboards, doors, cabinets, and walls for small teeth marks left by gnawing rodents. Pay special attention around pipes and wires which they like to chew through.
  
• Grease marks – These black sticky residue marks get left behind on walls and rafters as rodents travel the same routes repeatedly.
  
• Urine stains – Shining a UV flashlight helps reveal rodent urine stains not visible to the naked eye. Their urine gives off a pungent, musky ammonia odor.
  
• Tracks – Footprints and tail drag marks in dust provide evidence of where rodents are traveling.
  

As you inspect, also look for possible rodent entry points,points including:

• Holes in foundations, walls, rooflines or around pipes/vents
  
• Gaps beneath doors or around windows
  
• Uncapped chimneys
  
• Loose ventilation screens
  
• Compromised attic soffits or fascia boards
  
• Overgrown vegetation touching the home’s exterior
  
• Openings around utilities, pipes, and wires
  

Making note of all signs and entry points is crucial for effective rodent-proofing.

Rodent Control And Prevention Tips

With their strong teeth and flexible bodies, mice can squeeze through a hole the size of a dime while rats only need a quarter-sized opening. This makes sealing all possible entryways a priority.

Follow these tips to rodent-proof your home:

Seal Holes and Cracks

Carefully seal any holes, gaps, or cracks both inside and out with:

• Copper mesh – Stuff this durable, chew-proof mesh into wall voids and openings.
  
• Steel wool – Use coarse steel wool for a temporary seal until repairs can be made.
  
• Caulk or foam sealant – Inject caulking deep into cracks and crevices before sealing the surface with weatherproof silicone or expanding foam.
  
• Concrete or mortar – Use patching cement products to seal foundation cracks and other masonry gaps.
  

Sealing Utility Access Points

• Pipe penetrations – Seal gaps around plumbing, electrical, gas, and HVAC pipes or conduits where they pass through walls and foundations.
  
• Vents – Install vent covers to chimneys, attic, roof, and crawl space vents using corrosion-resistant mesh.
  
• Doors and windows – Inspect weatherstripping and sweeps around doors and windows to ensure a tight seal. Replace torn or missing sweeps.
  

Remove Access to Food & Water

Rodents need food and water to survive. Removing these vital resources makes your home far less attractive.

• Store all human and pet food in chew-proof glass, metal or rigid plastic containers to prevent access.
  
• Clean up any spilled bird seed, fallen fruit/berries from trees, and pick up pet food dishes after meals.
  
• Fix leaky pipes, clean gutters, and eliminate standing water sources rodents could drink from.
  
• Keep trash and recycling bins tightly closed and lined with metal or plastic bags rodents can’t chew through.
  
• Use a compost bin with a locking lid kept away from the house.
  

Reduce Clutter and Hiding Places

Rodents seek out protected, undisturbed areas and small spaces to build nests. Reducing clutter removes shelter options.

• Move stacks of boxes, equipment, and other stored items away from walls and up off floors.
  
• Clean out piles of debris from crawl spaces, attics, garages, and storage sheds.
  
• Trim back overgrown vegetation like shrubs, vines, and tree branches touching the home.
  
• Raise firewood stacks and lumber piles up off the ground.
  

Maintain Your Rodent-Proofing

Regular monitoring and maintenance is key to ensuring your rodent exclusion efforts hold up long-term.

• Inspect your home’s interior and exterior at least monthly looking for new signs of rodent activity.
  
• Reapply caulk, sealant, or weatherstripping if gaps reappear allowing access.
  
• Replace damaged vent covers and kick plates as needed.
  
• Keep vegetation trimmed back from the home.
  

Using Rodent Traps and Bait Stations

For active infestations, trapping is an effective and environmentally responsible approach before sealing entry points. Snap traps, electronic traps, and bait stations placed along known rodent activity routes will help remove current occupants. Always read and follow product instructions carefully.

Trapping tips:

• Use peanut butter, nut butter, bacon bits, or gumdrops to bait snap traps.
  
• Place multiple traps and check them daily to remove captured rodents.
  
• Position traps perpendicular to walls, with the bait end closest to the wall.
  

For ongoing prevention after exclusion work, secure tamper-resistant bait stations stocked with rodenticide blocks in high-risk areas like attics, crawlspaces, garages, and basements. Check and replenish bait as needed.

Note rodenticides pose poisoning risks to children, pets and wildlife so use with extreme caution.

When to Call a Professional Rat Exterminator

While diligent DIY efforts can effectively rodent-proof many homes, extensive infestations or challenging access points may require professional pest control services. Licensed experts have the experience, equipment, and rodent-proofing products to fully eliminate rodents and prevent re-entry.

Signs it’s time to call in an exterminator include:

• Visible rats in or around your home. Rats can be more difficult to exclude than mice.
  
• Significant structural damage from prolonged gnawing and nesting.
  
• Repeated failures keeping mice out despite your best efforts.
  
• Hard-to-reach entry points requiring tall ladders or other equipment.

Look for exterminators in your area that offer humane rodent removal services. They will conduct a thorough inspection, identifying all possible access points for a targeted rodent-proofing and exclusion strategy. Advanced sealing materials like metal kick plates, reinforced concrete, and commercial-grade sealants ensure even aggressive rodents stay out long-term.

Why Professional Rat Control Is Your Best Option

DIY rodent-proofing can effectively deter mice and rats from your home. However, advanced or long-standing infestations often require professional pest control services. Licensed exterminators have the tools and experience to fully eliminate rat occupants and prevent future entry.

Seeking qualified professionals is particularly advised if:

• Visible rats are spotted around your property
