Have you ever asked yourself, “What happens to bugs in the winter?”

Has your landscape experienced pest infestations and left you wondering “What can I do to prevent this from happening again?”

As other recommended fall treatments (such as biostimulants or mulching) do, fall dormant oil spray proactively protects your landscape. In particular, the spray protects against overwintering insects.

Of course, now you may be wondering, “What are overwintering insects and what is dormant oil spray?” Continue reading to find out what they are and what the treatment can do for your landscape.


Overwintering Insects: Where do bugs go in the winter?

Depending on the species, insects will hibernate, migrate, or overwinter. Those which survive through the winter are said to “overwinter” through the cold season.

Common overwintering insects in our area include:

Mites

Eastern tent caterpillars

Scale

Aphids

Here’s the problem: overwintering insects can leave an unpleasant surprise in the spring. When overwintering insects appear in the spring, homeowners typically realize the pests have wreaked havoc on their landscape. Even worse, once the problem attacks, it can’t be reversed.

Proactive care is the best care. For protection against overwintering insects, the most effective control is dormant oil spray.
