Oh june that sounds terrible! I have been lucky not to have arthropod invaders in my vegetables (knock on wood) yet, although I have a terrible invasion of black vine weevils in my front yard which have been devouring ever flowering plant I have planted out there. Last year I lost my entire crop of zinnias, cosmos, dahlias, and Shasta daisies to them, since there are so many of them that they eat the entire plant--leaving nothing to grow back. I have yet to find any in the backyard, thank God, but I need to find control for the front ASAP, but so far not much is working. See the pic below for the damage on my poor Shasta daisies--they're almost completely defoliated. I am very upset since no one else on my street seems to have them, and I raise flowers to enter at our county fair, but because of these wretched things I have had to scratch my entries for the past two years. Anyone know how to eradicate weevils? I've heard of the beneficial nematodes to kill the larvae, but is there anything to deter or kill the adults? I'm at my wit's end here!
