It’s impossible to tell if a tick is carrying a harmful pathogen without laboratory testing, so it’s best to kill any tick you find. Whether the creepy bug is crawling on your clothes, on your pet’s fur, or has bitten and attached to a member of your family, exterminating the tick will help keep you and others safe. Once the tick has been safely removed, simply drop it in a container with a bit of rubbing alcohol.
You could use a cup, jar, plastic container, or plastic bag to trap and drown the animal, but make sure the receptacle is sealed shut so the tick cannot escape. For example, if you use a regular drinking glass, put a plate or another flat object over the top to function as a lid. Leave the tick in the liquid until you’re certain it’s dead. To be extra cautious, use a container you don’t mind getting rid of and throw the entire thing away.
