REMOVE TICKS PROMPTLY

If a tick is found attached to the body (Figure 1),

seek assistance from medical authorities for proper removal,

or follow these guidelines:

(1) Grasp the tick's mouthparts against the skin, using

pointed tweezers (Figure 2).

(2) Pull back slowly and steadily with firm force.

  1. Pull in the reverse of the direction in which themouthparts are inserted, as you would for a splinter (Figure 2).
  2. BE PATIENT - The long, central mouthpart(called the hypostome) is inserted in the skin. It is covered with sharp barbs, sometimes making removal difficult and time-consuming (Figure 3, inset).
  3. Most hard ticks secrete a cement-like substance during feeding. This material helps secure their mouthparts firmly in the flesh, adding to the difficulty of removal.
  4. It is important to continue to pull steadily untilthe tick can be eased out of the skin (Figure 3).
  5. DO NOT pull back sharply, as this may tear the mouthparts from the body of the tick, leaving them embedded in the skin. If this happens, do not panic. Embedded mouthparts are comparable to having a splinter in your skin. Mouthparts alone cannot transmit disease because the infective body of the tick is no longer attached. However, to prevent the chance of secondary infection, it is best to remove them. Seek medical assistance if necessary.
  6. DO NOT squeeze or crush the body of the tick because this may force infective body fluids through the mouthparts and into the wound site.
  7. DO NOT apply substances such as petroleum jelly, finger nail polish, finger nail polish remover, repellents, pesticides, or a lighted match to the tick while it is attached. These materials are either ineffective, or worse, might agitate the tick and cause it to salivate or regurgitate infective fluid into the wound site.

Following removal of the tick, wash the wound (and your hands) with soap and water and apply an antiseptic.

Save the tick in a jar, vial, small plastic bag, or other container for identification should you later develop disease

  
symptoms. Preserve the ticks by either adding some alcohol to the jar, or by keeping it in the freezer. Storing a tick in water will not preserve it. Identification of the tick will help the physician's diagnosis and treatment, since many tick-borne diseases are transmitted only by certain species.
A tick needs a blood meal from a host in order to molt (progress to the next stage of it's life cycle), and to reproduce (lay eggs). This feeding process continues for several days to a week until the tick is fully engorged with blood. It then releases its hold on the host, drops off, and subsequently molts or lays eggs.

If the tick is infected with pathogenic organisms (for example, Borrelia burgdorferi, the agent of Lyme disease), it can transmit the infection to the host during the feeding process. As the tick feeds, the pathogens multiply, migrate to the tick's salivary glands, and are carried into the wound site along with the saliva.

Successful transmission of pathogens requires the tick to be attached for at least several hours. Therefore, the sooner infective ticks are removed, the less likely they will be able to transmit infection. It is impossible to tell if a tick is infected by just looking at it. Only analysis in a laboratory can determine infection status.
