We recently had our hemlocks sprayed with Merit to try to control the wooly adelgid that have infested them. The guy said that the white stuff stays on the branches after the insects are dead, so how do I know if it worked? Also, any ideas for organic controls?
After a bit, squish them. The "blood" or hemoglyph will not be as viscus and will be a different color. Eventually they'll be completely dry inside.
