If you have problem with leaf feeding caterpillars, contact us.
There are certain insects that while we need in our ecosystem are also destructive. The leaf feeding caterpillars are among the most problematic insects for defoliating
plants.
You’ve heard of The Very Hungry Caterpillar. It gives a great look at processes that these insects go through before they go through complete metamorphosis.
The Stage of the Caterpillar
The caterpillar is the immature stage of the moth or butterfly. They go through multiple molts before they cocoon and then become the adult insects that they are designed to be. There are usually four to six molts during the larval stage.
Caterpillars eat a lot before they go into the cocoon. This is because during the cocoon stage, they don’t eat anything at all.
Damaging the Plants and Shrubs
Caterpillars destroy plans by chewing on them. They will usually eat leaves and needles, but they can also bore into fruits, cones, and even trunks of trees. There is such a low number that will feed on trees and shrubs that they are not a major concern to damaging them.
One of the biggest problems with tackling the problem is the timing of spotting it. Because this is only an issue during the larval stage, it happens quickly. By the time you see evidence of it, the caterpillars are getting ready for metamorphosis. The pest treatments won’t benefit you and the plants at all.
You will need to look out for an infestation, though. If you see frass on the ground, it could be a sign of an infestation within the tree. This will lead to a lot more damage if the infestation is allowed to continue.
Dealing with Leaf Feeding Caterpillars
If you realize that you have a problem, you can use an insecticide. There are many that have proven to be effective, including pyrethroids. Bt is ingested by the larvae, making it one of the most effective for dealing with a pest problem.
You can also use a wetting agent to help manage the issue. A soap will help to prevent the caterpillars from feeding on the plants. This is good with the use of pesticides at the same time.
