Identifying the signs and symptoms of tree pests after a Rochester, MN winter can be tough. As your trees might be slow to perk up when the warmth of spring arrives, it’s all too easy to write off early signs of tree damage as simple growing pains. However, if you're dedicated to maintaining pest-free trees, stepping up your vigilance post-thaw can significantly improve the situation. At Maier Tree and Lawn, we always recommend careful surveys of your trees following the cold of winter just to make sure there aren’t any tree pests sneaking in under your radar.

Tree Pests and Their Nests Come in Many Forms

Webs and Webbing

An easy-to-spot indicator of a pest problem is thick webs and webbing covering leaves or heavily strung between branches. Some such webs and nests might look like thin strings, spider webs, or even dusty, moldy patches. Regardless of the outward appearance, monitoring for any kind of pest byproducts or activity is a helpful way to stay on top of a potentially damaging infestation.

Cocoons or Eggs 

Egg sacs or cocoons produced by tree pests are also an indication of a potentially harmful infestation. While hosting the occasional butterfly won’t be a real risk for your trees, if you find yourself spotting anything that might be an egg or larvae, don’t hesitate to reach out to Maier Tree and Lawn for a tree pest assessment. While some egg-laying visitors may not be dangerous, tree damage can occur quickly once eggs begin to hatch.

Holes, Divots, and Unusual Damage

If your trees are experiencing slow post-winter growth, it’s worth evaluating them for any subtle tree damage. Check the bark for unusual growths, look for discolored or wilting leaves, and search carefully for peeling or holes, which can signal the presence of wood-boring insects. Staying vigilant and aware of these signs throughout the winter months and afterwards, tree owners can catch potential infestations early and take necessary action to protect their trees.

Regular inspections and consulting with our professional arborists at Maier Tree and Lawn can help ensure the health and longevity of your trees.
