Those small white worms in your cherries are the larvae of the western cherry fruit fly — the one pest that quietly ruins a backyard cherry crop across the Treasure Valley. Impestable is a Boise pest control service that treats fruit-bearing cherry trees, not just houses, on a spray schedule built to keep your cherries clean.
What are the little white worms in my cherries?
Cherry worms are the maggots of the western cherry fruit fly (*Rhagoletis indifferens*), the insect behind nearly every “wormy cherry” problem in southern Idaho. In late spring and early summer, adult flies lay eggs just under the skin of ripening cherries. The eggs hatch into small white larvae that feed inside the fruit — so by the time you see a worm, the cherry is already infested from the inside. Because the damage happens out of sight and the flies emerge over several weeks, a single home-store spray almost never solves it. Control depends on treating during the narrow egg-laying window, on the right schedule, before the larvae are ever inside the fruit.
Why most pest control companies can’t get rid of cherry worms
Most residential pest control in Boise sticks to the house and yard — ants, spiders, wasps, and rodents. Those companies generally don’t treat food-bearing fruit trees at all. On the other side, tree-spray and arborist companies handle large shade and ornamental trees, but rarely run a precise, food-safe program timed to the cherry fruit fly’s life cycle. That gap is exactly why people searching for “someone who can get the worms out of my cherries” come up empty. Impestable is the rare Boise-area service that does both: structural pest control and a real fruit tree spray program for cherries, apples, and pears.
How we control the western cherry fruit fly
Most services aim to *reduce* cherry worms. Our cherry program is built to achieve complete control of the western cherry fruit fly — the goal is clean fruit, not just fewer worms. It’s a fruit tree preventative spray program, not a one-time visit, because the flies emerge over weeks and the treatment window has to be hit precisely.
- Inspect – Check the tree, the fruit, and the timing of the local fly emergence
- Identify – Confirm it’s the western cherry fruit fly (vs. other fruit tree pests) and where it is in its cycle
- Explain – Lay out the spray schedule for the season and what each treatment does
- Treat – Apply food-safe, OMRI-listed (organic) product options at each window through the egg-laying period, with sanitation guidance to clear fallen fruit
When should you spray cherry trees in Boise?
Timing is everything with cherry fruit fly. Most cherry trees need 3–4 treatments spaced 7–10 days apart, running from about late May through mid-to-late June — the stretch when adult flies are active and laying eggs in the fruit. Each spray has to land in that window: miss the start and the eggs are already inside the cherries, which can’t be “un-wormed” after the fact. We track local emergence each year and confirm timing with the weather, so your trees are covered through the whole egg-laying period rather than on a generic calendar date.

FAQ
- How do I get rid of worms in my cherries? The worms are western cherry fruit fly larvae. They’re controlled by spraying during the adult egg-laying window — before eggs are laid in the fruit — and repeating through the season. Once larvae are inside the cherry, that fruit can’t be saved, which is why timing matters so much.
- What are the little white worms in my cherries? They’re the maggots of the western cherry fruit fly, the most common cause of wormy cherries in the Boise area.
- Can you completely get rid of cherry fruit fly? Our program is built to achieve complete control — clean fruit, not just fewer worms — by hitting every treatment window through the emergence period. We’ll lay out exactly what that takes for your trees.
- When is it too late to treat my cherry tree? Once you can see worms in ripe fruit, the protective window for that crop has passed — but we can set up the schedule for next season so it doesn’t happen again. The best results come from starting before the cherries color up.
- Do you actually treat fruit trees, or just spray houses? Both. Unlike most residential pest control, we run a real fruit tree preventative spray program for cherries, apples, and pears.
