Dear Sara,
First let me apologize for the delay in getting back to you. Thank you for your report of the Asian Jumping worm or crazy worm to the Oregon Invasives Hotline. It is encouraging to know that there are citizens like you that are aware of the problem of invasive worms and willing to take measures to control them in your garden.

First I wanted to confirm that you actually have the Amynthas agrestis species? You note a brown clitellum and the Amynthas clitellum is white or creamy, and also notabley is flush with the body of the worm, which distinguishes it from other species. Also of course it jumps and thrashes when disturbed.
You have really good questions regarding how to control the worms and dispose of contaminated compost.
Here is a useful fact sheet: http://ccecolumbiagreene.org/resources/cce-jumping-worm-fact-sheet
Follow these simple steps to reduce the spread of Jumping Worms:
1. Do not buy Jumping Worms for composting, vermicomposting, gardening or bait.
2. Monitor your garden for Jumping Worms and their unique soil signature.
3. Avoid introducing organic mulch or soil from outside sources.
4. Plant bare root stock or seeds when possible.
5. If you have Jumping Worms remove and dispose of them and monitor your plants for drought and root loss.

Proper disposal methods include solarizing them or soaking them in alcohol.
