(Synonym: Wood-tick.)

State the character of the cutaneous disturbance produced by the ixodes.

The tick sticks its proboscis into the skin and sucks blood until it is several times its natural size, and then falls off; an urticarial lesion results. If caught in the act the animal should not be forcibly extracted, as its proboscis may be thus broken off and remain in the skin, and give rise to pain and inflammation. It may be made to relinquish its hold by placing on it a drop of an essential oil.

A thymol or carbolized boric-acid lotion will relieve the irritation.
