They don't like beer so if you put a container close to where your endangered plants are, they will be drawn to it, crawl in and drown (but what a way to go!). Also, they don't like copper at all and you can either put copper wire around your plants in a circle or I've seen copper tape at home and garden stores that does the same thing. Both of these ways are preferable to using strong chemicals and both work well but you will need to replenish the beer periodically. You could also try a big line of salt around your plants but this is rather unsightly and will need constant tending, especially in damp or wet weather. Good luck!
