It’s that time of year and flies are coming out of the woodwork…literally.  In cottage country the most common fly we see is the Cluster Fly

Cluster Flies are about 8 to 10 mm (.31 to .39 inches) long. They are dark grey, with black and silver (non-metallic) checkered stomachs. You can tell them apart from house flies in a couple of different ways:

• their wings overlap when they are at rest.
• they are larger, darker and slower-moving
• tend to “cluster” in groups
• give off a sickly-sweet odour when disturbed.

They are most commonly found in houses that are surrounded by large lawns or open parks.  Cluster flies hibernate in wall voids, attics, closets, and empty rooms. They tend to leave stains on walls and curtains and if they die in areas that can not be accessed – can attract other pests like larder beetles which will feed on the dead flies and then work their way through the rest of your home.

If you have a problem – it will present itself in the most obvious way as the days become warmer and the flies become more active.  You will see them gathering in windows or around well lit areas.

Prevention and control can be an arduous task as these little pests can access your house through the tiniest places.  Give Ross a call at 705-534-7863, or email us at ccpestcontrol@gmail.com  – and he’ll be happy to give you a hand.
