Ticks seek out a food source in a process called questing. Stimulated by heat, motion, and carbon dioxide, ticks will rest in low-lying vegetation awaiting a food source to happen by. They do not jump onto their host, but rather sit with front legs extended awaiting an opportunity to grab hold of something passing by. The tick will then begin feeding on the host for days or even weeks depending on the species of tick and will grow from 200-600 times its normal size.
The reason that a tick is very difficult to remove once it has attached to its host is due to the manner in which it feeds. The tick is equipped with a mouthpart called the hypostome, that have backward projections that once injected beneath the host’s skin make it difficult to pull out. Many tick species also inject a cement-like substance to keep the tick firmly in place.
Safe Embedded Tick Removal
- Clean a pair of pointed tweezers in rubbing alcohol.
- Grasp the tick with tweezers as close to the head and mouthparts as possible.
- Firmly but gently pull the tick straight out without crushing it.
- Wash the area with soap and water.
- If the embedded tick does not fully detach, call your physician.
Do Not . . .
The use of any foreign substance such as Vaseline®, nail polish remover, or matches will traumatize the tick and may cause it to defensively regurgitate its gut contents. The gut contents of a tick can contain the bacterium responsible for Lyme disease.
