In the past I have refered to long periods of cloudy weather as a 'light drought'. In cool weather, with thick clouds, food producing plants tend to goof off. But they are hatching a plan in the mean time.
Once the light comes back they go nutz. Its a beautiful thing. And of course the bugs want to take advantage of all that lush, new growth, so they have a hatching party and start to chow down.
The sooner we deal with the bugs when they are small, the better. I have a solution I use for spot treatment of emergent bug-beasts:
Use 2 cups 80 or 100 proof vodka to soak 1/8 cup ground thyme, 1/8 cup ground rosemary, 2 Tsp ground cayenne pepper for 2-5 days, preferably the full 5 days. (in glass Mason jar, swish concoction about 2 times daily to mix well)
Mix 1 part of the above extraction with 15 parts water, spray at will, soaking the bugs. Repeat application every 3-4 days till signs of emergence and bugs ends. (***You may wish to test this first to see if it harms your plants in any way.***)
