June to October, cluster flies in spring

Fly control in Metro Vancouver

The species tells you where the problem is. Fruit flies mean a drain or a bin. A sudden mass of big flies means something died in the structure.

Signs

How you know

  • Small flies hovering over a drain, the recycling or the fruit bowl

Species

What lives here

Fruit and vinegar flies
Breeding in anything fermenting. Drain film, bin bottoms, recycling, overripe produce, beer taps.
Drain and phorid flies
Breeding in the film inside drain lines and under cracked tile. A stubborn phorid population can mean a broken drain.
Cluster flies
Overwinter in attics and wall voids in large numbers, then show up at interior windows on the first warm days.
House and blow flies
Filth breeders. Blow flies indoors in quantity point at a carcass.

Treatment

How we deal with flies

  1. Identify the species, then find and remove the breeding material. That is the fix.

  2. Biological drain treatment to strip the film that fruit and drain flies live in.

  3. Void and attic treatment for cluster flies, plus sealing the way they get in.

  4. Find and remove the carcass where blow flies point at one, then treat the site.

Prevention

Keeping them out

  • Rinse recycling and wash the bins out
  • Refrigerate fruit through late summer
  • Flush and brush floor and mop-sink drains weekly
  • Deal with rodents early, before one dies somewhere you cannot reach

Questions

Flies, asked and answered

Why do fruit flies come back after I clean?

The breeding site is almost never on the counter. It is the film inside a drain line, the bottom of the recycling bin, or a forgotten potato. A few grams of fermenting material supports the whole population.

Where are the flies at my upstairs windows in March coming from?

Your attic or wall voids. Cluster flies spent the winter there and they are heading for light to get out, which is why they appear indoors on the first warm day.
