You can’t see them, but they’re likely eating your landscape right now. Spider mites are nearly invisible to the naked eye, but in the hot, dusty summers of Eastern Idaho, they can brown out an entire shrub in a matter of days.
If your plants look "dusty" or scorched, you aren't just dealing with heat stress. These tiny arachnids thrive in the dry conditions of Idaho Falls, sucking the life out of your trees and shrubs from the underside of the leaves.
By the time you notice the fine webbing, the damage is often already severe.
Catching an infestation early is the only way to save your plants. Here are the early signs of spider mites in Idaho and the professional steps you need to take to stop them.
Spider mites are tiny arachnids that feed on plants by piercing their leaves and sucking out the juices. They’re hard to see without a magnifying glass, but their damage can be devastating.
They tend to live in colonies and gather on the underside of leaves, especially during hot, dry weather.
Ironically, if you’ve used chemical insecticides in the past, you might be more vulnerable to spider mites — pesticides can kill the beneficial bugs that normally keep spider mites in check.
Spider mites thrive in dry, dusty conditions and often show up in the heat of summer. Common causes include:
They spread easily from plant to plant and can quickly establish a colony.
Want to catch spider mites before they cause serious damage? Here’s what to look for:
Early infestations cause tiny white or yellow spots on leaves, where mites have pierced the surface to feed.
Look under leaves and along stems for delicate, silky webbing. This is a telltale sign you’ve got a spider mite colony setting up shop.
If you look closely (or use a magnifying glass), you may see tiny red, brown, or yellow mites moving slowly across the underside of leaves.
As the infestation grows, so does the damage:
A large spider mite population can seriously weaken shrubs, trees, and even lawn areas.
Here’s the tricky part: regular insecticides don’t work on spider mites. That’s because they’re not true insects — they’re arachnids, like ticks and scorpions.
Instead, try one of these approaches:
Pro tip: Always follow application guidelines. Using the wrong product or timing it poorly can stress your plants or reduce effectiveness.
