japanese beetles are back
frederick, md. a couple of years ago i put down milky spore to combat Japanese beetles. for several years there was very little infestation. however this year they are back big time. the past 2 winters have been colder than normal. could the milky spore have been killed by the colder weather. should I reapply
the milky spore?
We have seen no information confirming the effectiveness of the current formulations of milky spore. Last summer was wet, so we are seeing more Japanese beetles. https://extension.umd.edu/sites/default/files/_images/programs/hgic/Publications/HG78%20Japanese%20B... vw
