Tree Insects

Experienced Defense against Common MN Tree Insect Infestations

Protecting your trees against insect tree damage can be a difficult task, especially once an infestation of insects has already begun. Unfortunately, many tree insects can cause great harm to the trees they infest, leaving the trees in your yard or property to fight a losing battle against ravenous insects.

At Kraft Tree Service, our tree insect specialists offer detailed advice to property owners in the west Twin City suburbs. We have the skills and knowledge needed to help you protect against insect tree damage and combat rampant infestations of boxelder bugs and the emerald ash borer in MN.

One of the newest and most dangerous insects to appear in Minnesota, emerald ash borers have caused major damage to trees since their discovery in the area in 2009.

Our experience handling these attacks allows us to offer the advice and service you needed to save your trees and avoid future infestations.

Certified Arborists Providing Tree Insect Control Advice

Our staff is committed to helping you protect the trees on your property, and provides detailed advice on your options for combatting damage caused by a wide range of tree insects, including:
Aphids - Aphids feed on the sap tissue in leaves or through the bark. They cause curling and distorting leaves, stunt growth and causing yellowing of leaves.  Due to their feeding on sap tissue they are easily controlled by systemic insecticides.
Albert (Bud) Mayfield, Florida Department of Agriculture and Consumer Services,
Ash Flower Gall Mites - Initiated by the feeding of microscopic mites on the male flowers of ash trees. The galls do not affect the tree health, but are considered unsightly. Control of the flower gall is difficult, and most treatments focus on increasing the vitality of susceptible trees.

Birch Leafminer - Larvae of a small wasp. The larvae feed between the layers of a leaf and are protected from parasites and predators by the leaf. The symptoms include brown patches on leaves which expand and can kill the leaf entirely. Control measures need to be systemic or timed to coincide with early larval feeding.
Steven Katovich, USDA Forest Service,
Boxelder Bugs - Boxelder bugs feed on seeds of boxelder trees and many spend winter months in nearby buildings. The major damage from these insects is their presence in nuisance numbers on windows and siding of homes.
Joseph Berger,
Bronze Birch Borer - Bronze birch borer larvae feed on the inner bark, causing the canopy to thin and die back. Birch trees in the urban environment are often stressed, attracting this insect. A treatment program should include insecticide applications and pruning to remove the infested areas.
Steven Katovich, USDA Forest Service,
Elm Leafminer - Similar to the Birch Leafminer, these are small "fly-like" wasps whose larvae feed between the layers of a leaf. Symptoms include brown patches when these areas die. Control for the elm leaf miner needs to be applied before the mines of the leaf develop.
Whitney Cranshaw, Colorado State University,
Emerald Ash Borer - An exotic beetle discovered in Michigan in 2002. The adult beetle nibbles on the ash foliage causing little damage. The larvae feed on the inner bark of the tree disrupting the trees ability to transport water and nutrients. The beetle was discovered in Minnesota in the spring of 2009. Look for exit wounds in the bark that have characteristics of a capital letter D.
Eric R. Day, Virginia Polytechnic Institute and State University,
Honey Locust Plant Bug - Cause damage by feeding. They inject saliva, which aids in digestion and uptake of the plant cell contents. The saliva destroys the cells causing leaf curling, distortion and sometimes leaf death. This pest is easily controlled with systemic and topical insecticides.
John A. Weidhass, Virginia Polytechnic Institute and State University,
Japanese Beetle - Discovered in Minnesota in 1991. Japanese beetles feed on the foliage and the flowers of ornamental plants including lindens, larch and corn and grape plants.
Doug Stone, Mississippi State University,
Sawflies - Affect pine and spruce trees by consuming needles in feeding groups. An insect that can shorten and disfigure a young spruce or pine. Proper treatment may control this insect.
Andrea Battisti, UniversitÓ di Padova,
Soft Scales - Aphid creatures which feed on the sap of the tree. The immature scales feed on the foliage where the mature scales feed on the branches. Dormant oils and contact insecticides can be effective, but only if they are applied to the unprotected crawler stage. Timing of insecticide application is critical to effective control.
United States National Collection of Scale Insects Photographs Archive, USDA Agricultural Research Service,
Mites - Very common and can be found on every coniferous plant. The mite population can dramatically increase in a single season with hot, dry conditions, turning interior foliage yellow to rust brown. A long-term treatment needs to be maintained for adequate control.
