I am still tending to believe the attack on the kids last night was from a highly mobile insect. The pots were spread out quite a bit and the attacker was still able to get to all of them. I built shelves on the wood fence on my property line and all were on their shelves which have a separation from each other of about 3 feet. I've moved them inside the birdcage for now, I'd like to get any other pest control tips. thanks.
