Uncover Common Types of Winter Tree Pests: Essential Insights
Pets make the winter even tougher on trees and shrubs in Montclair. During colder months, certain pests look for shelter and food in your trees, causing damage that may go unnoticed until spring. Understanding these common winter tree pests and how they affect your landscape can help you protect your greenery. Learn what to watch out for and how to keep your trees safe this winter.
Scale Insects
- These are small insects with a big impact. These pests, covered in a shell-like armor, range in size from tiny pencil-tip dots to as large as ladybugs. They harm trees and shrubs by draining their fluids, often going unnoticed until leaves wilt or branches die.
Their clever camouflage makes them look like harmless bumps on branches, but beneath the surface, they’re causing serious damage. Scale insects sap the vital nutrients your trees and shrubs need to thrive by using their piercing mouthparts.
Tiny Spider Mites
- Spider mites may look like tiny greenish-yellow spiders, but their size, just 1/64-inch long, makes them nearly invisible to the naked eye. Shake a branch over white paper and check for streaks after wiping your hand across it to detect them. These streaks are crushed adult mites.
Feeding mites leave discolored dots on leaves and create a stippled, dull appearance. In the Montclair area, they are particularly damaging boxwoods, burning bushes, spruces, and junipers.
Bagworms
- Bagworms get their name from the clever bags they create using silk and bits of plant foliage. This camouflage allows them to blend into the tree, making them difficult to detect. In the fall, the larvae pupate and transform into moths. Female moths then lay up to 1,000 eggs in each bag, which survive the winter and hatch in the spring.
When these eggs hatch, the young larvae are only about ¼ inch long, but their voracious feeding allows them to grow to nearly a full inch. Unfortunately, bagworm infestations often go unnoticed until late summer, when their damage causes plants to brown irreparably.
Harmful Lace Bugs
- Lace bugs are small, flat insects no larger than ⅛ inch. They feed on the undersides of leaves, making them difficult to spot. Their wings have a delicate, translucent appearance, giving them the “lace” in their name.
During winter, lace bugs remain dormant as eggs, waiting to hatch in spring. Their feeding leaves behind stippled, discolored leaves, much like spider mites. Lace bugs are particularly troublesome for azaleas, pieris, and cotoneaster shrubs, though they may target other plants as well.
Protecting Against Winter Tree Pests
- A proactive plant health care program is your strongest defense against winter tree and shrub pests. If your landscape is consistently cared for with strategic, well-timed treatments, pest populations stay low enough to prevent plant damage. However, responsible applications are essential to maintain nature’s balance. Broad-spectrum insecticides, for example, eliminate harmful pests but also wipe out beneficial insect predators.
For instance, you might eliminate aphids on burning bushes, but without their natural predators, you could end up with a worse spider mite infestation. That’s why expert care is essential. Professionals know the right materials, rates, and timing to target specific pests without harming beneficial ones. American Tree Experts Inc. maintains this delicate balance.
