Chiggers are what bother me the most. I can pull a tick off of me but chiggers stay for a few days. The bad ticks are the deer ticks. They have a red design on their backs, most of the ticks you'll see are dog ticks. They have a brown pattern on them. The dog tick does not carry lyme disease. I've never actually found a deer tick and I only know of one person who has ever contracted lyme disease. Here are some websites on ticks, so you can figure out which ones are the bad ones.

The second link is a write up concerning ticks in the Carolinas but many of their ticks are the same as what you will see in Maryland.
