Are these spider mites and if so how do I get rid of them?

Expert Response

Thank you for your questions.  We can't identify the source of webbing just through photos.  Most spider mites' webbing is located near foliage, and does not extend between trees.  This is probably webbing from common predatory spiders.  If it is spider webbing, you are fortunate that they are there--preying upon the pests you really don't want!
