Dormant oil application in early spring and seasonal insect control to protect fruit trees throughout the growing season in Davis County.
Fruit trees need different care than ornamental trees. They attract specific insects, they have a narrow treatment window in early spring, and missed timing can cost you an entire season of healthy fruit. Our fruit tree spraying program starts with a dormant oil application before blossoms open and continues with insect control treatments as needed through the growing season.
Ornamental trees need feeding and general insect prevention. Fruit trees need that plus targeted protection during the stages when they are most vulnerable.
The biggest difference is timing. Fruit trees go through a specific cycle each spring: dormancy, bud swell, blossom, and fruit set. Each stage attracts different pests and responds differently to treatment. Dormant oil must be applied before buds open. If you wait until blossoms appear, the window has closed and the treatment can damage flowers and developing fruit.
Fruit trees in Davis County face pressure from aphids, borers, codling moth, spider mites, and other insects that target fruit-bearing wood specifically. Many of these pests overwinter as eggs on bark and branches. Dormant oil applied at the right time smothers those eggs before they hatch, giving your trees a clean start to the growing season.
Without early spring treatment, insect populations build quickly once temperatures rise. By the time damage is visible on fruit or leaves, the problem is well established and harder to control.
This program is designed for homeowners with fruit-bearing trees that need protection from insects and seasonal pests.
If you have ornamental trees and shrubs (non-fruit-bearing), the Tree and Shrub Program covers deep root feeding and insect prevention on a four-application schedule.
If you have both fruit and ornamental trees, we can set up both programs together for your property. Contact us and we will evaluate your full landscape.

The dormant oil spray is the foundation of this program. It is applied in early spring while trees are still dormant, before buds begin to swell and open. The oil coats bark, branches, and bud scales, smothering insect eggs and overwintering larvae before they can hatch.
Dormant oil is effective against aphids, borers, scale insects, spider mites, and the eggs of several moth species including codling moth. It is a contact treatment, meaning it works by physically covering the target rather than using a chemical poison. This makes it one of the safest early-season treatments for fruit trees.
Timing is critical. The spray must go down before the early blossom stage. Once blossoms open, dormant oil can interfere with pollination and damage developing flowers. We monitor spring conditions in Davis County and schedule applications based on actual bud development, not a fixed calendar date.
After the dormant oil application, we monitor for insect activity through the growing season. If pest pressure develops after blossom, we apply targeted insecticide and miticide treatments to control active problems.
Common mid-season threats to Davis County fruit trees include aphid colonies on new growth, spider mite infestations during hot and dry stretches, and codling moth larvae that bore into developing fruit. These are treated on an as-needed basis depending on what your trees are dealing with.
Not every fruit tree needs mid-season spraying every year. Some seasons are worse than others for specific pests. We evaluate conditions and treat only when it is necessary.
Davis County homeowners with fruit trees often deal with the same recurring issues. Here is what to watch for and what causes it.
Wormy or damaged fruit. This is usually codling moth. The adult moth lays eggs on developing fruit in spring. Larvae bore into the fruit and feed inside. Dormant oil in early spring reduces the overwintering population, and mid-season treatments can target active moths if needed.
Sticky leaves and black residue. Aphids feed on new leaf growth and excrete honeydew, a sticky substance that coats leaves and surfaces below the tree. Sooty mold grows on the honeydew, turning surfaces black. Heavy aphid infestations weaken the tree and reduce fruit quality.
Leaves curling or dropping early. Spider mites and aphids both cause leaf curling. Spider mites are tiny and hard to see without magnification. They are most active during hot, dry weather. Look for fine webbing on the undersides of leaves.
Holes in bark or sawdust-like material around the base. This is borer activity. Borers tunnel into tree trunks and branches, weakening the tree’s structure and disrupting nutrient flow. Dormant oil helps with some borer species, but active infestations may need additional targeted treatment.
Premature fruit drop. If fruit falls before it ripens, insect feeding or poor pollination may be the cause. Insect damage to developing fruit triggers the tree to drop it early. Ensuring the dormant oil is applied before blossom protects pollination and reduces insect pressure on young fruit.
The dormant oil application does not produce a visible result you can see immediately. It works by preventing insect populations from establishing in the first place. What you should notice is cleaner fruit, healthier leaf growth, and fewer pest problems compared to untreated trees.
By mid-summer, trees on this program typically show fuller canopy, less leaf damage, and better fruit development than trees that were not sprayed. If mid-season insect control is needed, results from those treatments usually appear within one to two weeks.
Fruit trees that have gone multiple seasons without treatment may take a year or two on this program before insect populations are consistently under control. The first season brings the biggest improvement, but ongoing annual treatment gives the best long-term results.

Yes. Dormant oil is a refined horticultural oil that smothers insect eggs on contact. It does not harm the tree when applied during dormancy. The key is timing. Applied before bud swell, it is safe and effective. Applied after blossoms open, it can damage flowers and interfere with fruit set.
Apple, cherry, peach, pear, plum, and apricot trees all benefit from dormant oil and seasonal insect control. If you have other fruit-bearing trees or are not sure whether your trees need spraying, contact us for a free evaluation.
Yes. If you have both fruit and ornamental trees, we can run both programs on your property. The schedules complement each other and we can coordinate visits to minimize disruption.
We can still help with mid-season insect control treatments for active pest problems. The dormant oil application will go on your schedule for the following spring. Starting mid-season is better than waiting another full year.
We serve Davis County, Utah, including Bountiful, Layton, Kaysville, Farmington, Centerville, Clearfield, Syracuse, Fruit Heights, Woods Cross, West Bountiful, and North Salt Lake.
