Earwigs yuckie

Earwigs are moisture loving buggers which love the night life and sleep during the day. They surround themselves around moist ares such as boards, vines and weeds and mulches. Try reducing their hidding places and moisture levels. You can trap them

with a cat or tuna can with about an 1/2 inch or so with oil (fish and tuna oil <<< food of choice). YOu can use vegetable oil with a bit of bacon grease. Another sure way would be to use a roll of cardboard (paper towel roll) or newspaper placing at dusk to the corrupted area and in the morning take the newspaper or card board and dunk in soapy water. With this treatment you can do this until your waking eye see's no more.
As for your growing enviroment, can't help you there, growing indoors is my forte. It's extremely hot here and watering my houseplants that have homed on my patio get watered 3-4 times a week with daily misting (when I remember) and with that routine they are hangin' in there. Maybe a member will chime in and narrow your enviroment for you...gl
