> Any suggestions on eradication? We also have a problem with hornets. They are shinny black and the size of a bumble bee. They had made a home in the electrical ceiling unit in the greenhouse, we filled it w/foam spray. Now they are just swarming and really aggressive. They are between me and my chiles! The only time it's safe in the garden or greenhouse where my seedlings are is after sunset. Any ideas on how to kill them??? HELP! Mary-Anne
