you can expect them back every spring. Sure enough, they were back in
the spring. :-(

What zone are you in?

I'm in zone 6 but they winter over I know as far north as zone 5.


I've only had them once before outside a few years ago. I can only hope

our
winter is cold enough, long enough to kill any eggs. It was interesting

how
they liked the warmer zone stuff, what we call annuals here, and stayed

off
anything perennial (other than being in the grass for a week or so). Si
nce
I toss annuals after frost hopefully any surviving eggs will go with th
em.

It's better to burn them or bury them deep if you can. Or if that's not
possible, bag them
for trash pickup. Here they infested even the dandelions and native shru
bs
they were so bad
one year.
