Fruit Flies Behavior & Habits
Understanding how fruit flies behave helps prevent infestations
Fruit flies are drawn to anything ripening or fermenting. A single female lays up to 500 eggs, and the full lifecycle takes only 8 to 10 days, so a handful of flies turn into hundreds in a couple of weeks. They also breed in places you wouldn't expect: drain gunk, dirty mops, sticky cans in the recycling, even the gap under your dishwasher.
Fruit Flies Risks & Dangers
What fruit flies can do to your health and property
Health Risks
Fruit flies can carry bacteria from drains and trash onto food, counters, and dishes. They're not as risky as house flies, but they're still a sanitation concern in any kitchen.
Property Damage
No structural damage. Their presence is just a sign there's organic material somewhere that needs to be cleaned up.

Fruit Flies in Boise & the Treasure Valley
Fruit fly calls in Boise pick up sharply from late August through September, right when garden tomatoes, peaches, and apricots start ripening across the Treasure Valley. Older homes in the North End, Garden City, and the Boise Bench with backyard fruit trees see the heaviest waves. Farmer's market hauls and backyard produce are almost always the original source. You don't really catch fruit flies from outside; you bring them in.
How We Eliminate Fruit Flies
Professional treatment for complete elimination
Fruit fly control comes down to finding and removing the breeding source. No amount of spraying works without that step. We help locate the hidden spots (drains, recycling, forgotten produce in the back of a cabinet), set traps to knock down the adults you're seeing right now, and walk through prevention so the next bag of stone fruit doesn't bring them right back.

Fruit Flies Questions Answered
Common questions about identification, prevention, and treatment
Where do fruit flies come from so suddenly?
Fruit flies usually ride in on produce as eggs or larvae, or slip through window screens drawn to the smell of ripening fruit. Their 8 to 10 day lifecycle means a handful of flies turn into hundreds in about two weeks.
Do fruit fly traps really work?
Traps knock down the adults you can see, but they won't end the infestation on their own. The classic apple cider vinegar trap catches a lot of flies. Without finding and cleaning the breeding source, new ones keep hatching every few days.
Why do fruit flies keep coming back?
You probably haven't found every breeding source. The spots people miss most are the rubber splash guard on the garbage disposal, the bottom of a recycling bin, a damp mop head in the closet, and the drip tray under the fridge. Fruit flies can breed in a teaspoon of fermenting goo, so it doesn't take much.
