Pruning Mistakes That Invite Pests Into Your Home

Proper pruning keeps trees healthy, encourages strong growth, and grabs the attention of prospective buyers and tenants. When pruning is done hastily or incorrectly, however, it can open the door to much more than a messy-looking tree. In fact, some common pruning mistakes can invite pests right into your property.

If you’ve ever dealt with termites, carpenter ants, squirrels, or even raccoons, you already know the damage they can do. What you may not realize is that poor tree maintenance often plays a big role in attracting them in the first place.

In this brief article brought to you by Driscoll Tree Service, we take a closer look at a few pruning missteps that can make your trees (and your home) more vulnerable. If you'd rather consult an arborist from a reputable tree company, then contact Driscoll Tree Service. Our live representatives are on standby to take your call or message today.

Mistake #1: Cutting Too Close to the Trunk

One of the most common pruning errors is making cuts too close to the trunk or a major limb. Also known as flush cutting, removing what's known as the branch collar will threaten the tree's ability to properly seal off wounds. The branch collar is the tree's natural defense zone, and a cut can:

• Create entry points for fungi and disease
• Accelerate decay within the branch or trunk
• Attract insects, including beetles, borers, and ants

As that wood begins to rot, pests will turn the space into a nesting site and food source. Worse, the rotting could compromise the structural integrity of the tree if the decay spreads far enough. Extensive or deep rot can demand a tree removal.

The right approach is to make clean cuts just outside the branch collar. A professional arborist knows exactly where to make these cuts for quick and natural healing.

Mistake #2: Over-Pruning or Topping the Tree

While it might seem like a good idea to "give it a fresh start," removing too much of a tree’s canopy in one go will cause stress that can lead to pest issues. Over-pruned trees are:

• Weaker and more susceptible to disease
• Prone to “sucker” growth that attracts sap-feeding pests like aphids and whiteflies
• More likely to develop sunscald and bark damage

Topped trees also tend to regrow awkwardly. These tangled areas become perfect hiding spots for insects and small animals. Plus, they can block airflow and sunlight.

Stick to the “no more than 25%” rule - never remove more than a quarter of the tree’s foliage at once. Proper tree service by a trained and experienced professional involves structural planning to keep the tree healthy and the pests at bay.

Mistake #3: Leaving Stubs or Ragged Cuts

Not cutting enough can also lead to trouble. Leaving behind branch stubs will prevent the tree from sealing the wound. These stubs begin to die off and rot. Next thing you know, you've got an easy entryway for insects and decay. Pests that LOVE deadwood include:

• Termites
• Powderpost beetles
• Carpenter ants

If ignored, the infestation can travel from your tree into your deck, your fencing, and eventually into your home. So, use sharp and clean tools when making precise cuts, and avoid leaving behind stubs. When in doubt, call Driscoll Tree Service to hire a uniformed professional.
