Wintersong, how did nematodes get into your answer?
Silly me assumed that was the active ingredient that killed the VW lavae.
I check my containers by hand I'm afraid and anything that dies in my garden due to this nuisance, is not worthy and wont get planted again!
It makes me angry to lose beloved plants by any means or waste money on replacements but I'd be more angry with myself for using chemicals that could potentially harm good wildlife
