We provide tree and shrub insect control services to property owners in the Treasure Valley area including Boise, Kuna, Meridian, Eagle, Nampa, Star, Caldwell, Middleton and surrounding areas.

There are a lot of different types of trees in the Treasure Valley and each one has unique insect challenges.  We can stay ahead of most problems with a regular maintenance program that includes an early spring dormant oil and late spring systemic insecticide. Some trees will require additional specialized treatments.  We can help you figure out a customized maintenance program for your trees to protect them from insect invasions.

Dormancy refers to the time of year when deciduous trees and shrubs have lost their leaves and are not actively growing. Dormant oil sprays can be used any time between leaf drop in the fall and bud break in the spring. Here at Zing we begin our dormant oil applications in February as long as Mother Nature cooperates. It must be applied in certain temperatures without a lot of moisture present, so we watch the weather closely for these applications.

Spring is a great time to get ahead of insect issues. Protect your investments with preventative applications.

Dormant oil is basically a waxy film that covers the trunk and branches of deciduous trees and shrubs suffocating any insect eggs that are present. This is a very safe and effective way to stay ahead of insect problems. The purpose of dormant oil applications is to kill mites and insects, such as scales and aphids, that have spent the winter months on the trees and shrubs.

Our spring fertilizer drench has a systemic insecticide protecting the tree from many insect problems. Trees absorb this insecticide with a fertilizer treatment and transport it all throughout their leaves and branches. When insects try to take up residence and nibble on the tree they die. It’s a great way to protect your trees each spring for the upcoming battle of the bugs.

Our licensed arborist can recognize, treat and apply protection against devastating insect invasions. If not recognized and treated early, insects can cause a lot of damage quickly.

Aphids are sap-sucking insects that attack all types of deciduous trees and shrubs. Aphids can cause damage in a variety of ways including stunted growth, mottled and wilted leaves, yellowing, and in some cases possible loss. Aphids can be green, brown, golden, orange, red, white, grey or black. Aphids suck the juices and nutrients out of leaves, stems and tender plants. They feed in clusters usually on the undersides of leaves. The most common symptom that you may notice with an aphid infestation is the sticky and thick substance of “honeydew” that they leave behind when they are feeding on plants. This sticky substance can be found on sidewalks, driveways and vehicles near the tree(s) and can invite wasps, ants, and fungal infections. Another symptom you may see is wilted leaves.

Early detection is key, so regular monitoring of your landscape is the first important step to keeping aphids under control. The most common way to control aphids on smaller trees and woody plants is to spray them. Treatment can be done with a systemic applied in the spring as a preventative measure or with injections on individual trees as needed. The injection is quickly absorbed into the vascular tissue of the tree and disbursed throughout the leaves and branches.

Ash Borer

The Ash Borer is an invasive wood-boring beetle that feeds on ash trees. This insect’s larvae feed on the vascular tissue of the tree affecting its ability to transport water and nutrients. The symptoms will include thinning of the canopy and dieback of limbs, visible exit holes on the tree’s trunk, and sloughing off of the tree bark. This is not an insect to ignore. Infested trees can die after two to three years, but heavily infested trees can die within one year. We treat borers with trunk injections and this will typically need to be done every couple of years to protect the tree from re-infestation.

Bronze Birch Borer

The Bronze Birch Borer is a wood-boring beetle which attacks all birch species. The adult is a copper/bronze colored slender beetle. The larva, which does the damage, is unseen. It feeds on the vascular tissue under the bark. The Bronze Birch Borer normally attacks trees which are already stressed or declining. A birch infested with Bronze Birch Borer will start showing dieback at the top of the tree, and will eventually extend to the major branches and main stem. Emergence holes may be seen on infested branches and trunks.

Cottony Maple Scale

Cottony Maple Scale is a soft scale insect that attacks a large variety of woody plants.  Its favored host is maple trees, although it has been found on a number of other species as well.  Heavy infestations may kill weakened trees and cause branch dieback on healthy trees.

Large amounts of honeydew are produced which eventually cause the leaves to be covered with greyish/black colored sooty mold.  The sooty mold reduces the aesthetic features of maples and honeydew can become a nuisance as it coats patios, decks and vehicles, and attracts wasps. A noticeable 1/4″ – 1/2″ white egg sac that looks like a cotton ball is the symptom to look for with Cottony Maple Scale. This pest can be controlled with either a foliar spray or trunk injection depending on the size of the tree.


Mites are similar to insects, but belong to the spider family. The most common ones are Spider Mites and Gall Mites. Mites are tiny, almost microscopic, and appear as tiny specks on the underside of the leaf. Spider Mite damage shows up as speckling and mottling of the leaf or needle causing the plant to appear grey or washed out and will limit the growth of the plant. Gall Mites will have the presence of the gall, an abnormal growth on the leave, stem or twig. Gall Mites live and feed inside the gall.

Sequoia Pitch Moth

Infestations are noticeable by the pink, reddish or gray mass that protrudes from infested trunks and limbs. As the larvae feed and grow under this mass it grows larger and turns a darker gray. They typically infest pine and select conifers. Treatment is done with trunk injections. Freshly pruned and mechanical damaged areas to trunks and limbs attract egg-laying SPM’s during the months of February and September, so try to avoid creating these types of wounds during this time period. Remove resin masses and crush any visible larvae for further control.
