not sure about the bugs, but the plants look really stretched. a plant "stretches" looking for the light. this could mean a couple of things for you. the first being, your plants spent so much time trying to get to the light, that they didn't form a healthy root structure. not good, they'll probably die. to fix this look @ your lights. make sure you have them as close as possible without burning the plants, and you might want to check the color temp etc...my signature has a link to a really helpful thread on lights. I did notice tin foil on your setup, tin foil is not really recommended because of heat and conductivity issues, try some flat white paint.

hope this was helpful.
