Tick heads left in the skin can be removed with a sterilized needle or tweezers, according to LymeNet Europe. Moisture can help remove the small mouthparts left behind. Allowing the tick head to remain in the skin may increase the risk of infection.
Tick heads generally disintegrate or fall off on their own, reports Weston Pediatric Physicians. The chances of infection are low, they claim, because the potentially dangerous bacteria and organisms live in the tick's stomach. However, if the tick is not removed properly and grasped around the abdomen, it may vomit secretions into the wound and vastly increase the chances of infection.
When removing a tick, the tick must be grasped with tweezers around the head as close as possible to the mouth, according to LymeNet Europe. Grasping at the abdomen can not only pressure the tick into vomiting but also rip it in half, leaving the head behind. The tick should be pulled straight away from the body with gradually increasing force. Although ticks usually bite into the skin at an angle, WebMD warns that twisting the tweezers can also cause the head to break off and remain in the skin. Once the tick is removed, the affected area must be cleaned and disinfected.
