I have two evergreen trees planted outside of my front porch. I first noticed these little cocoons looking things hanging from the pine leaves, and almost looking as if it were pine cones. Then I notice my evergreen trees were turning brown, and I thought that I may have used too much water while watering my garden, or that I have purchased diseased plants. Then a neighbor mentioned to me that I have bagworms, an that no insecticide could them. So I decided to use wasps insecticide, only because I knew that I could use it while standing back a few feet,
It worked. But have to spay my trees every season at the beginning of summer.

So, I decided to post this question to get additional information.

Thanks, amberspytwo.

I don't think it's bagworms. Pine trees don't have leaves.

Here is a good article about how to rid yourself of bagworms.
