Capital City Exterminators

Mammal Pest Control

Most mammal pests that we encounter at Capital City Exterminators are part of the rodent family. Mice and gophers are the most common groups that we encounter in Edmonton and throughout Alberta.





  • The two most common mice we encounter in Alberta are the deer mouse and the house mouse.
  • They live in attics, burrows, wall voids and other hard-to-reach areas.
  • One pair of mice can create over 200 offspring in just a couple of months.
  • Mice can run up any vertical surfaces including wood, brick, metal, cables etc.
  • Most mice live anywhere between 15 to 18 months.


  • Unexplained holes in bags of food.
  • Chewed wires and furniture.
  • Seeing a mouse during the day is a sign of a heavy infestation, as they are usually nocturnal animals.
  • Scratching sounds in the night.


  • Each mouse contaminates 10 times the amount of food that it eats. Contaminating can be as serious as the spread of salmonella onto surfaces where food is prepared.
  • The Hanta virus is a life threatening disease which is transmitted by deer mice. Found in urine and faeces of mice, humans can become sick if they come into contact with contaminated dust from droppings or nests.
  • Mice can be difficult to control and present a serious menace to homeowners by eating through valuable pieces of furniture, electrical wiring and destroying whole food stores.


Our technicians will place bait boxes containing a poison around your home. The poison we use will ensure that the mice will not smell once they have died. If any become trapped behind a large piece of furniture or inside a wall cavity, they will simply dry out and will not rot. Our pricing includes the supply and installation of the bait boxes containing the poison, and an inspection of the home to identify any entrance points used by the mice.

We recommend you keep the bait boxes in place in your home as the poison will continue working for months/years after it is placed. At some point you may run out of poison in the boxes. You can then book us to come and re-bait the boxes.

Eliminate the reason rodents are being attracted, which is food. Ensure any open food packages are sealed in Tupperware or air tight containers. This includes pet food, bird food and any other foods present in your kitchen.

Our technician may identify entrance points for the mice. Make sure to eliminate these entrance points by filling any holes and closing any doors to the outside. Remember, our pest control methods will kill any mice in the house, but they will not stop more mice entering.

Any commercial accounts who wish to have pest control services for mice please see our Commercial Services page.





  • Gophers are medium-sized rodents which vary from about 15-40 cm in length.
  • Their fur color can vary from very dark to almost white.
  • Often confused with moles or ground squirrels, we treat for all in the same way.


  • They burrow in lawns and gardens and can quickly destroy your landscaping.
  • They can also destroy vegetable patches by feeding on tubers, roots and bulbs.


We use a bait gun to dispense a rodenticide pellet called Rozol into the hole of the gopher. Click here for a copy of the chemical data sheet for this poison.

  • The poison will cause the gopher to die, sometimes inside the hole and sometimes they will die outside on your lawn. In this case they are usually removed by scavengers.
  • If your property backs onto parkland getting the problem under control can often be difficult. We can treat the gophers that are currently using your land, but they will likely be replaced by neighboring gophers from the untreated parkland.
