Hi, We live near Baltimore. There is a small pine tree in our front yard. It kind of started to become brown(thought due to hot sun), but it was still lot alive. We also planted Rocket hybrid flowers beside it. We went for a vacation and by the time we came back, the tree is full brown, the Rocket hybrid started blooming, but the bugs started eating the leaves and also weirdest thing, it is climbing up on the walls. There are lots of them. on the ground and hanging on to the dead pine tree. It is carrying the leaf material and covered in it. Please help.

Snail case bagworms? If so would love specimens.

Yes, after some more research, found it to be bagworms. But, how can I eliminate them.

At full development size before turning into moths, chemicals are pretty useless for control. The best thing now is to handpick them and then straight into a container of hot soapy water. The female moth remains caterpillar-like and never leaves the bag. Don't ask the mating ritual (males fly) LOL. The female dies in the bags after laying eggs and larvae are protected until hatching next season.

At least, the Arborvitae (probably) that they were eating is about the only thing I have seen them consume. Get that removed, plant something else in fall.

Thanks for the information Greg. (Must be arborvitae is the most commonly planted favorite of theirs in suburban landscaping around me Smiling )
