Carpenter Ant

Carpenter Ants

Size: 6 – 25mm

Colour: These ants are commonly all black, but can have a red thorax (mid section of ant).

Carpenter ants can live both in and out of doors. Typically they prefer moist areas of wood but have been found in many other locations such as styrofoam or blown insulation. Locations of colonies also varies and can be anywhere from an old tree stump in your yard to a window or door frame, ceilings and wall voids. The most common signs of an infestation is a steady movement of ants around the interior/exterior of your building, sawdust piles or the sound of chewing.

Flying ants are another good indication of a problem. This usually means the problem is quite advanced and has been there for a few years. Typically these ants will swarm in July then disappear, however this can happen when the temperatures are quite warm for long periods.

Acrobat AntAcrobat Ants

Size: 3mm

Colour: black, sometimes light brown

These ants are found in very tight areas such as wall or ceiling voids. Their abdomen (tail section of ant) is shaped like a heart. These ants will typically be in high numbers and treatments are very similar to that of the carpenter ant. The most common signs of evidence are travelling lines of ants and debris being pushed out from ceiling or wall voids. The debris is usually a mixture of dirt, dead ant parts or small bits of sawdust.


Size: 2-20mm (variety of species)

Colour: brown, grey, black (depending on the species)

Spiders and their webbing can become quite unsightly around the exterior of a building. Typically areas close to lakes or rivers can have issues with not just spiders, but their webs. A good exterior treatment will take care of the spiders, but will not remove the webs. In any case where an exterior treatment is going to be done it is recommended that the webs be removed first by power washing or by broom. The treatment will be very effective for about two months.


Size: 8cm (adult)

Colour: brown or grey with lighter to white colour belly

Mice can become quite the nuisance in any building. They can gain access by manipulating their body to fit through the smallest of holes. Chewing, climbing, burrowing and jumping added to their arsenal make them quite the pest to battle sometimes. Perimeter inspections, followed by sealing and exclusion work can help in the long run but there is no way to guarantee it will totally solve your problem. Interior stations that are filled with a rodenticide can also be used as a method of treatment. The units themselves are about the size of the palm of your hand and are child and pet proof. These will be placed in strategic areas where the mouse problem seems to be at it’s worst.



Size: 6-7cm (little brown) 10-12cm (big brown)

Colour: brown/black

There are two types of bats in southern Ontario that may be a problem for you, the big and little brown bat. Infestations commonly are in areas such as attics or under siding. They are most noticeable and active from spring until the fall when insect populations are at their highest. In cooler months the bats will remain dormant or migrate to caves. A typical service is to do a full exclusion job to all areas. In Ontario bats are protected and it is illegal to kill them. To allow the bats an escape route, we install exit only doors during exclusion work. Approximately one week later a follow up will be scheduled to ensure all bats have vacated. The doors are then removed and the final sealing is completed. Due to breeding during mid summer months it is best to do this type of work in the spring or the fall.

Cluster FlyCluster Flies

Size: 6-8mm

Colour: black

Cluster flies are noticeable around buildings in the spring and fall. If they have overwintered in your building you will see them clustering around the biggest and brightest windows. Since they think this is the way out they will spend all their time there. In the fall you will see similar activity, and also see them on the sunniest and warmest side of the exterior walls.


Size: 15mm (adult)

Colour: dark brown, yellowish

Cockroaches are rarely a problem in the Muskokas. However, there is one native to the area that you may have seen, the Pennsylvania Wood Roach. Not known to be indoors very often these roaches typically can be found outside amongst decaying organic material such leaf or wood piles and downed trees. Due to the area in which some cottages are located this may be a problem you encounter.


Size: 5mm (full grown adult)

Colour: light brown/reddish

Every year, the number of reported cases of bedbugs increases in Ontario. Although the majority of these problems are around metropolises such as Toronto, cases are steadily increasing in the Muskokas. Bedbugs and their evidence can usually be noticed on beds, bed frames and headboards. In more advanced infestations they can be found on night stands, dressers, picture frames, curtains, baseboards, light fixtures, couches, tables, and a variety of chairs. As they only feed on one item (human blood) and are attracted by carbon dioxide emissions, they are going to be very close to you.

Treatments for bedbugs are always done in two services, the second service being done two weeks after the initial. The treatments include a variety of techniques such as vacuuming, steaming cleaning as well as traditional methods such as spraying and dusting. A detailed prep sheet is sent out prior to service. It is very important to prepare as much as you can. The better the preparation, the better the results.


Size: 2mm

Colour: reddish brown

Anybody that has had fleas before knows they can be an itchy nuisance. Fleas can be a problem to either a cat or dog and will feed on human blood if necessary. They can also go for long periods of time without feeding. Treatments consist of spraying baseboards, carpets and areas close to where the infested pet may rest. If they rest on a bed or mat it is recommended this be washed and dried at high temperatures. Having the pet treated for fleas by a vet is also recommended.



stinging insectStinging Insects

Size: 1-2cm

Colour: black and yellow

Wasps and hornets are the two stinging insects that have likely built a nest close to you. Both breed of insect can by dangerous if colonies are allowed to grow to large sizes. Treatments are directly to the nests themselves and results are usually immediate. If problem is not solved within 24 hours, a follow up service will be done immediately.
