If you have any junipers or cedars....keep an eye out for bagworms! Bagworms will eat the foliage off of your plants...and severe infestations will kill your plants!
Minor infestations can be controlled by manually removing any "bags" you may find. More severe infestations will require an insecticide. They also spread quickly! So if you find them on one juniper or cedar, they will likely be on others!
Fortunately they are rather easy to control and will cause minimal damage as long as you keep an eye out and catch them early on!
