Our process

Step 1: Rodent Perimeter Exclusion


  • Physical


  • Steel wool

  • Steel mesh

  • Spray foam


  • A thorough inspection of building foundation from interior and exterior to identify potential entry and exit points.

  • Any insecurity is secured with a combination of steel wool, spray foam and steel mesh where necessary.

  • Severe structural insecurities are brought to you attention, and a construction plan is laid out.

  • Any insecure weatherstripping or door seal is identified and repaired.


  • Prevents new rodents from entering your home.

  • Forces rodents in your home to feed at bait stations rather than going outside to forage.


Step 2: Rodenticide Bait Station Treatment


  • Chemical


  • Anti-coagulant rodenticide

  • Temper proof bait stations


  • Rodenticide bait blocks or packets are secured in a thick plastic tamper proof bait station and placed in strategic discreet locations throughout the interior and exterior of the home.


  • Discreet, locked, and tamper-proof bait stations are safe for all pets and family.

  • Rodenticide bait contains a desiccant which dives the rats out of the home in search of water.

  • Desiccant dries out the dead rats and will prevent any foul odour.


  • Must be implemented in conjunction with rigorous cleaning and sealing to eliminate other food sources and draw cockroaches to the bait.


Step 3: Rodent Monitoring


  • Physical + Preventitive


  • Baited sticky trap


  • Baited sticky traps are placed in strategic locations

  • Ongoing checkups on bait stations keeps your home protected and rat free.


  • Ongoing monitoring of any new rats active on the premises.


Beware of Discount Pest Control

  • These companies use low quality or insufficient baits that can cause rodents to die inside the walls and stink up your home for months.

  • Rats are one of the most adaptive and invasive pest species. Unless a full and thorough treatment is done you could end up with constant re-infestations with Rats that are too clever to feed on bait stations.


What you need to know for an effective Rat treatment.


If you suspect you have a rat infestation clear and complete information is the first step to getting rid of them. Here are a few facts, myths, and tips that will help you to make a well informed decision about what to do next.


Identifying Rodents

Identifying Rodents


How to Identify Rats

There are two common species of rat in North America, the Norway rat and the roof rat.

The foraging behaviour and physical characteristics of these species vary considerably.

The species of rat will determine the most effective way to get rid of them.

It is important to distinguish a rodent infestation between mice or rats. Baby rats look very similar to mice.

The best way to tell them apart is the size and shape of their head and the size of their droppings.

Rat Shape, Size and Colour

  • coarse hair, usually dark brown to black fur

  • greyish-white underbelly.

  • short, blunt snout

  • body measures up to 25 cm (10”) in length NOT including their tail

  • a male weighs on average 350 g (12 oz) and a female 250 g (9 oz).

  • the tail is shorter than the head and body,

  • their ears are short,

  • both ears and tails are covered in scales and nearly hairless

Rat Droppings

The best indicator of a rat infestation is the presence of their droppings, found along frequently travelled rodent pathways, nesting and feeding areas.

  • shiny, black and blunt capsule shaped pellets

  • roof rat droppings: shape of rice with pinched ends,

  • Norway rats droppings: shape of tic tacs with rounded ends

  • measure 18 to 20 mm long.

  • larger than mouse droppings

Rat Behaviour and Characteristics

  • most active at night time, sightings in daylight are rare

  • emerge in the daytime if hiding place is disturbed

  • acute sense of smell and hearing, adept at avoiding traps and remaining hidden during daytime hours

  • usually only travel within 30 meter radius of nest to find food and other materials

  • gnaw on walls and utility lines to create entry points and sharpen teeth

  • true omnivores consume almost anything including:

    • meats, fruits, grains, and nuts

    • Dead animals

    • they are capable of catching small fish and rodents

  • require constant fresh water to survive, make their nests as close to a water source as possible.

Rat Reproduction Habits

  • breed throughout the year

  • female produces anywhere from 4 – 7 litters per year

  • gestation period is 21 days, up to 14 young per litter

  • achieve sexual maturity in 2 – 5 months.

  • maximum lifespan: 3 years

  • common lifespan in the wild: 1 year

  • rats increase reproduction rate to restore their numbers when a significant portion of the population is eliminated

  • Females can become pregnant immediately after giving birth, and nurse one litter while pregnant with another litter

  • If food is restricted for pregnant rats, extend their pregnancy up to two additional weeks until their offspring are a normal and healthy weight



How do I know if I have a rat infestation?

The best person to tell if there are rats active in your home is YOU. 

Since rats can live deep inside the walls, and only emerge when it is time to forage for food.

Spotting any of the following signs is a good reason to believe you have an rat infestation.

Addison performs rat inspections if you are hearing gnawing, squeaking or scurrying inside the walls but you cannot find any signs of rodent activity.

Give us a call to schedule an inspection in seconds.


  • stealthy nocturnal pests, be most vigilant after dark

  • spotting live rat could mean several more are out of sight

  • may be spotted scurrying for shelter when startled by a light or loud noise

  • if seen during the day may indicate a severe infestation

  • Use baited sticky traps to effectively gauge the severity of a rat infestation.


Rat droppings are usually the first sign of an infestation in your home.

  • shiny, black and blunt capsule shaped pellets

  • roof rat droppings: shape of rice with pinched ends,

  • Norway rats droppings: shape of tic tacs with rounded ends

  • measure 18 to 20 mm long.

  • larger than mouse droppings

  • The most common place to find droppings:

    • under sinks

    • behind stove, refrigerator

    • behind laundry machine and dryer

    • attics and basements

    • underneath couches

    • near garbage receptacles and recycling bins

Chewing, gnawing, holes

  • holes chewed in food packaging

  • holes chewed through walls and floors to sharpen their teeth,

  • creates entry ways into the home

  • holes are approx. 2" in diameter

  • chewed electrical wiring

  • holes chewed in cushions or fabrics for nesting material

  • slick grease stains along transit routes or around entry holes

Scurrying or scratching noises

  • Roof rats are adept climbers and can make their way through ducting, vents, eletrical conduits on upper floors

  • Norway rats are not as able climbers, and are more active on lower floors and basements

  • The sound of rodents in the wall can amplify making tiny mice seem much larger

Foul odour

  • Rat droppings and urine give off a distinct foul odour

  • Even if you cannot see or hear evidence of mice in your home their odour is an effective way to determine where mice are active



Can I get rid of rats on my own?

If you are able to identify a rat infestation in the earliest stages you can take steps to eliminate the infestation on your own.

Unfortunately, because urban rats are so well adapted to survival, they are able to outsmart most commercially available snap traps and sticky traps.

Rat infestations can grow very quickly and pose significant health risks.

The sooner you implement an effective professional pest control program, the easier a rat infestation will be to eradicate completely.

Where to look for rat activity

  • burrow for shelter in concealed areas

  • anywhere from basements to attics

  • nesting sites include:

    • space between double walls

    • floor joists

    • areas under cupboards

    • small spaces under sinks

  • Norway rats not adept climbers: inspect foundation for structural insecurities at ground level

  • Roof rats can climb walls and other vertical surfaces and jump up to 30 cm vertically: inspect insecurities in the roofline, chimney, flashing, soffits 


  • Seal up holes around the perimeter of your home using steel wool to keep rodents out.

  • Remove potential nesting sites including

    • leaf piles and thick mulch

    • stop feeding outdoor birds

    • move outdoor compost away from home


  • Clean up food and water sources inside and outside your home.

  • Use tight-fitting lids for compost and garbage cans inside and outside the home.


  • Bait commercially available snap traps with cheese, marshmallow, peanut butter or any other fatty sugary substance

  • Use baited sticky traps in areas where you see elevated activity to gauge the level of the infestation

What doesn't work

  • Comercially available bait stations use insecure boxes that could be pried open by pets or children and ineffective bait that isn't palatable or effective in eliminating rats

  • Most rodents in the Toronto area are now resistant to warfarin, avoid this rodenticide



How did rats get into my home?

Rats are most common in dense urban centres, where there is ample food waste and shelter for them to procreate rapidly.

  • excavate extensive burrow systems

  • live in large, hierarchical groups in underground areas such as sewers and cellars

  • excellent surface and underwater swimmers

  • may enter through sewage or drainage pipes, toilets

  • climb slim round metal poles several feet to entry points

  • may enter through holes and cracks in the foundation of the home

  • open doors and windows

  • all homes are susceptible to rat infestation

  • enter the home in search of shelter food sources and water and safe places to reproduce



How serious are rats?

  • Rats can transmit disease through the air from viruses found in their fecal droppings and urine.

  • rats forage for food and nesting materials at night time, they may contaminate food preparation surfaces and food storage areas putting you at risk of contracting pathogens and bacteria that they leave behind.

  • HPS Hantavirus Pulmonary Syndrome is a lung infection that you can get by breathing in tiny particles contaminated with rodent urine, saliva, and droppings.
