Flies are more than just a nuisance—they can pose serious health risks by spreading disease. With over 120,000 known species worldwide, including house flies, fruit flies, sewer flies, and cluster flies, these pests are especially common in late summer and early fall and can infest homes and businesses rapidly.
Flies are attracted to decaying organic matter and can contaminate food by transferring pathogens from one surface to another. That's why early intervention and professional treatment are essential.
At Cal-Rid Pest Control we specialize in comprehensive fly control in Calgary. Whether you're dealing with a handful of fruit flies in the kitchen or a large cluster fly infestation in the attic, our licensed team has the tools and experience to eliminate the problem at its source.




Often found around garbage and food.


Attracted to ripened or fermenting fruits and vegetables.


Thrive in moist environments, often coming from organic buildup in drains.


Common in fall and winter, found in attics and windows.
Proactive prevention is the first line of defense. To reduce your risk of a fly infestation:
1.Keep your kitchen clean – Wipe down counters, and clean up spills right away.
2.Check between and behind appliances – Food debris often gets stuck in tight spaces.
3.Seal garbage, compost, and recycling – Use tightly sealed bins and empty them regularly.
4.Inspect doors and windows – Use fine mesh screens and seal any gaps or cracks.
5.Store food in air-tight containers – Especially fruits, sweets, and meats.
6.Limit outdoor lighting at night– Lights attract flying insects.
7.Clean drains regularly – Use a wire brush, bio-foam, or drain cleaner to remove buildup.
