Important Insect Control For Trees

Here at ArborScape, we pride ourselves on continuing education and staying updated on the latest trends and issues in the forestry industry and the surrounding areas. Not only that, but we believe in sharing our knowledge with you, so you can stay informed so as to identify any issues and rely on us for insect control for trees to keep them safe and healthy.

If you know anything about gardening or landscaping, then you know there’s always a risk of trees and plants attracting an array of insects. While some are great to have in your yard, others can bring about disease and death.

So here are the latest updates on tree insects and the potential diseases they can bring. We want you to stay updated on this so you can be aware of the diseases being spread and what type of insect control for trees you may need.

We’ve already talked at length about the Emerald Ash Borer, which has been confirmed in Littleton. But it’s good to remember that while they’re dormant during the winter, it’s never a bad option to have a certified arborist take a look at your ash trees as a precaution.

Insecticides are the best way to control the Emerald Ash Borer. Here at ArborScape, we use a spray method that goes directly on the trunk, as well as bark injections. These can be used as either preventative treatments or rescue treatments.

Another tree disease to watch out for is Dutch Elm Disease; or DED. It’s an invasive fungal disease that can clog up an elm’s vascular system and can cause wilt or death of the tree. This disease is carried out by elm bark beetles as they travel from tree to tree. 

Symptoms of DED may include yellowing leaves that turn brown as well as leaf curling. And when the bark is peeled back, you can see brown or black vascular streaking.

If you suspect your elm may have this disease, contact a certified arborist for a full diagnosis. If your tree does have DED, we’ll take a sample and send it off to CSU for culturing and confirmation. If the disease is confirmed, the only treatment is to go in and remove the tree to prevent any further damage to the surrounding areas.

Next on the lookout list is the Ips Beetle and the effect they have on spruces. This is the fourth year in a row that this insect has had a high population in the metro area. However, they tend to only attack stressed and overmature trees, so your young spruce should be fine.

However, there are always at least two flights of adults per season, so getting the proper insect control for trees on time is pertinent to keeping your spruce safe.

And finally, we have the Tussock moth; a pest from birth. As caterpillars, their hairs can act as a skin irritant and can cause rashes or itching, and they start to migrate toward the top of trees to eat needles from the branches of spruces, Douglas-firs, and true firs. And as these moths grow, the juveniles can travel by wind while the mature moths fly from tree to tree.

Insect Control for Trees

While these pests can be treated with a preventative spray application, it is a timely treatment to ensure the stop of adult emergence. In fact, all of these treatments are time-dependent.

In order to be fully effective, these treatments must be administered either before the larvae hatch or as soon as symptoms are noticeable, and during the growth season while the bark and soil can still absorb the ingredients from the insecticide.

While it may be difficult to ascertain the extent of the damage done by these pests in winter, it’s still a great time to call one of us out for any necessary insect control for trees. Our certified arborists can do full assessments of your trees to diagnose any issues and find a way to treat them.

For instance, with the Tussock moth, we can predict potential moth problems by surveying for egg masses before the eggs hatch in late spring. Meanwhile, EABs leave tracks or holes in the bark as they burrow, and ips beetles leave yellow or rust-colored boring dust that accumulates in tree branch crevices as they tunnel into the trees.
