One part Clorox to nine or ten parts water is what I've always heard.

Yes, that's what I use.

Thank you for the fast reply. I dug up a bed and have never see them. I am surprised this happened. 15 years and never a outbreak of these ugly things. Maybe it was because of all the rain.

and i hope you understand .. you use bleach .. not chlorox ...

unless you like paying extra for the name brand ... the generic is sufficient ...
