Ticks: part 1
Please remember that this blog cannot be a substitute for the experience and services of a pest management specialist, and not all aspects of this important topic can be covered in a blog. In this first of two weblogs on ticks, we'll review the two most common species encountered and of greater medical importance to humans. This first group consists of two species of deer tick (also called black leg tick) and the single star tick. Usually encountered outside the home while walking in yards / parks or hiking, they are important transmitters of organisms that cause diseases in humans. In the next blog (August), we'll review the second group of two species (the American dog and the brown tick), which are usually brought into homes on pet dogs, and sometimes transmit organisms that may cause disease in humans.

Recognition. Ticks are arthropods (with an exoskeleton and articular appendices) but are not insects. Adults are usually more than 1/8 long, oval, and flat. They lack antennae (found in insects), and usually have 4 pairs of legs (insects have 3 pairs).
Seed ticks are birds that have only 3 pairs of legs. They may or may not be able to transmit disease organisms to humans, depending on the tick species.

identification. Correct identification of species is critical because different species may transmit different disease-causing organisms. If you get bitten, be sure to carefully remove the sample (see below), place it in rubbing alcohol, and take it with you to the doctor. A pest management specialist with a microscope is often necessary to confirm species identification.
Black-legged tick or deer (scientific name is Ixodes scapularis).
Unsorbed adults are about 1/8 tall. The female is dark reddish brown, but the back half of her body is orange-brown. Males have their entire body reddish brown. The abdomen does not contain small oblong-shaped areas divided by grooves along the posterior margin.
Lone star tick (scientific name is Amblyomma americanum).
Uninjured adults are about 1/8 inch long, but when congested with blood, they are 7/16 inch long and 3/8 inch wide. It is reddish brown, but becomes gray when congested with blood. The female has a white to silver spot in the center of her back, while the male has several white spots along the back margin. The abdomen contains small oblong areas, which are divided by grooves along the posterior margin.
Transmission of pathological organisms
Black legged tick or deer tick. This tick is an important vector for Lyme disease (the most common animal-borne disease in the United States), the bacteria that causes human-loving anaplasmosis, and babesiosis (a malaria-like disease caused by primary parasites).
