Tip Weevil


Commonly effects blue Spruce and Pines in our area. These insects attack the main leader or new growth in the top of the tree by laying eggs. These eggs become larva that feed on the trees new growth. The larva then matures to adults and emerges in the summer. They then hibernate at the base of the tree through winter and the cycle continues.

We recommend spraying Spruce and Pine trees in the spring and fall to prevent Tip Weevil damage.

Aphids


Commonly effect deciduous trees (Aspen, Willow, Maple, etc.) and bushes in our area. Aphids feed by sucking sap from the leaves of plants and can cause several kinds of injuries. In high numbers there can be a decline in plant vigor. Aphids also excrete large amounts of sticky droppings, which may become a significant nuisance and allows for growth of associated sooty molds. Aphids may cause leaf curling and discoloration.

We recommend multiple solutions depending on severity.

Systemic Soil Injections have proven to be most affective.

Topical spray applications also may be required in some cases.

Treatment is done during spring and summer.

Mites


This pest can affect deciduous (Aspen, Willow, etc.) and conifers (Spruce, Pine, etc.) Mites can cause trees to yellow or gray with premature leaf drop/needle drop and decreases vigor of plants.

Mites must be treated with Miticide while active.

Treatment for mites is most effective during the summer.

Scale


Scale can be found in Aspens and in mature conifers (Spruce, Pine, etc.) Scale attacks the trunks and larger limbs of both young and old trees. Dieback of the branches, limbs, needles and sometimes the entire tree can die where the infestation are not controlled. The scale insects suck sap from the phloem cells, depriving the tree of food manufactured in the leaves and needles.

Treatments vary from soil injections using systemic to topical sprays depending on the crawling stages.

Scale is treated mainly during spring and summer.

Borer


Borers make holes in the truck off your trees. They can be in Aspen trees (deciduous) and Spruce trees (conifers)

Borer in spruce and pines can be controlled with our regular preventive maintenance programs.

Mountain Pine Beetles/ Spruce Beetles/Ips Beetles


The western forest is currently infested with beetles destroying native trees. (Ponderosa, Lodge pole, Scotch and Douglas fir) These beetles feed on the tree for a year or two that kills entire forest.

Colorado State University Cooperative Extension states” Mountain pine beetle is the most important insect pest of Colorado’s pine forests. MPB often kill large numbers of trees annually during outbreaks. Trees that are not growing vigorously due to old age, crowding, poor growing conditions, drought, fire or mechanical damage, root disease and other causes are most likely to be attacked. For a long-term remedy, thin susceptible stands with emphasis on leaving well-spaced, healthy trees. For short-term controls, spray, cover, burn or peel attacked trees to kill the beetles. Preventive insecticide sprays can protect green, unattacked trees.
