Why Dormant Oil Sprays Are a Spring Game‑Changer

When it comes to tree care in Michigan, spring is all about getting ahead of problems—not reacting to them later. One of the smartest early‑season strategies? Dormant oil sprays.
Simple, effective, and powerful, this treatment is like hitting the “pause button” on tree pests before they ever get a chance to cause damage.

What Is a Dormant Oil Spray?

Dormant oil sprays are applied early in the spring, before trees fully leaf out. The oil works by coating overwintering insects and insect eggs, smothering them before they hatch—no chance to feed, multiply, or stress your trees.

“These pests overwinter on trees and become active as soon as temperatures rise.Common pests include:
  • Aphids
  • Scale insects
  • Spider Mites
  • Lace bugs
  • Spongy Moth (Formerly Gypsy Moth) 
  • Eastern Tent Caterpillars

If these pests sound tiny, don’t be fooled. Left untreated, they can cause big problems once the growing season begins.

 

Why Dormant Oil Sprays Matter in Michigan 

Michigan’s seasonal swings create the perfect environment for tree pests to overwinter and explode in spring. A dormant oil spray in Michigan helps stop that cycle early—before insects wake up hungry and destructive.

Benefits include:

  • Preventing pest infestations before they start
  • Reducing the need for stronger chemical treatments later
  • Promoting healthier tree growth all season long

Think of it as tree pest prevention, not pest control after the damage is already done.

The Best Time to Apply Dormant Oil

Timing is everything. Dormant oil sprays are most effective when applied:

  • In early spring
  • Before buds open
  • On days when temperatures stay above freezing

This small window makes professional timing and application especially important.
