Indian Hawthorn problem

Posted by heelsfan 8 (My Page) on

Something is destroying my Indian Hawthorns. For years they have looked great and this year was no exception.....until a few weeks ago. Something (caterpillars) have made hunderds of what look like cocoons on a few of the plants. Two others look fine. The "cocoons" are brown and white in color and are 1"-2" long. What are they and how do I get rid of them.

Oh my gosh! You have a bad bagworm infestation. The create a protective 'bag' around them with the leaf material. Commonly seen on arborvitae. Pick off by hand or spray! They've been on there for a while.

Here's more info. Get them off, make sure the plant is watered. Give it time, to see if it recovers.

Just a note from experience, when you handpick them be sure to kill them. I had them on a shrub years ago and spent a good bit of time picking them off one by one into a bucket. I left the bucket on the porch overnight and the next day they had crawled out of the bucket and into my foundation shrubs! I still get the willies thinking about it.

RE: Indian Hawthorn problem

They are all over three of the bushes. Is there an insecticide that will kill them?


BT - Bacillus thuringiensis

RE: Indian Hawthorn problem

Bt won't help at this stage of the caterpillars' life cycle. It needs to be applied when they are very young and small.

Truly, I know you don't want to hear this, but handpicking is your best option at this time. It won't take all that long, and you can do a little bit every day.
