The safest ways to dispose of a tick are to drop it in rubbing alcohol, flush it down the toilet, seal it in tape, or trap it in a closed container. The one thing you should never do is crush it with your bare fingers, which can expose you to disease-causing organisms inside the tick’s body.
Four Safe Disposal Methods
The CDC lists four recommended options, and which one you choose depends on whether you want to save the tick for identification or just get rid of it fast.
- Rubbing alcohol. Drop the tick into a small cup or jar of isopropyl alcohol. This kills the tick within minutes and is the most reliable method if you don’t plan to have it tested.
- Sealed container. Place the tick in a zip-lock bag or small jar with a tight lid. This is the best choice if you want to save it for identification or testing later.
- Tape. Fold a piece of clear tape tightly around the tick so it’s completely enclosed. The tick can’t escape or be accidentally crushed.
- Flush it. Drop the tick directly into the toilet and flush. Ticks can survive being submerged in water for two to three days, according to research from the University of Rhode Island, but they can’t swim. The force of a flush carries them through the plumbing. Use the toilet, not a sink drain, since sink traps may not move enough water to push the tick through.
Why You Should Never Crush a Tick
Squeezing a tick between your fingers can release its internal fluids, which may contain the bacteria and parasites responsible for Lyme disease, anaplasmosis, and other infections. A study on Lyme transmission found that crushing a tick’s body during removal increased the chance of pathogen exposure compared to pulling it cleanly, though the difference wasn’t statistically significant for Lyme specifically. The concern is greater with other tick-borne pathogens that may spread more readily through contact with tick fluids. The bottom line: always handle ticks with tweezers, a tissue, or a tick removal tool rather than your bare hands.
Methods That Don’t Work
A few common approaches sound effective but either fail or make things worse.
Burning a tick with a match or lighter is risky for two reasons. The tick’s hard outer shell protects it from brief heat exposure, while your skin has no such protection. Worse, if the tick is still attached and senses danger, it may regurgitate its gut contents into the bite wound, increasing the chance of disease transmission.
Submerging ticks in bathwater, running them through a washing machine, or soaking them doesn’t reliably kill them. Research shows ticks can survive underwater for days without apparent harm. Hot, soapy water and swimming pools are equally ineffective. If you find a tick after a bath or shower, you still need to remove and dispose of it properly.
When to Save the Tick Instead
If the tick was attached to your skin (or your pet’s skin), saving it for identification can be genuinely useful. Different tick species carry different diseases, and knowing the species helps a doctor or veterinarian narrow down what to watch for. The Mayo Clinic recommends at minimum taking a clear photo of the tick before disposing of it.
To preserve a tick for testing, place it in a sealed container or zip-lock bag. Label it with the date you removed it and where on the body it was attached. If you want the tick identified but not formally tested, a clear photo submitted to a free service like the University of Rhode Island’s TickEncounter program can get you a species ID at no cost.
One important note if you’re saving a tick from a pet: don’t put it in rubbing alcohol. Veterinarians advise against this because alcohol can interfere with the lab’s ability to identify the species and test for diseases like Lyme. A dry sealed container works best until your vet can examine it.
Tick Testing Labs and Costs
Commercial tick testing typically costs between $50 and $200 per tick, depending on the lab and how many pathogens you want screened. Turnaround times vary, but most labs offer standard and rush options. Some state programs offer free or reduced-cost testing for residents. Pennsylvania, for example, provides free testing for state residents through its Tick Research Lab.
Testing a tick doesn’t replace monitoring yourself for symptoms. A negative result doesn’t guarantee you weren’t exposed, and a positive result doesn’t mean you were definitely infected. But the information can help guide conversations with your doctor, especially if symptoms develop weeks later.
Cleaning Up After Removal
Once the tick is disposed of, clean the bite site with soap and water or a standard antiseptic. Do the same for your tweezers or removal tool. If the tick’s mouthparts broke off during removal (which sometimes happens if the tick was pulled too quickly), don’t dig around trying to extract them. The skin will typically push them out on its own over time, similar to a splinter. Aggressive digging increases the risk of secondary infection.
Keep an eye on the bite area for the next 30 days. A small red bump right after removal is normal and doesn’t indicate infection. What you’re watching for is a rash that expands over several days, particularly one that develops a ring or bullseye pattern, along with any fever, joint pain, or flu-like symptoms that appear in the weeks following the bite.
Disposing of Ticks Found on Pets
The process is essentially the same as for ticks found on people, with one key difference: your veterinarian may want to see the tick. PetMD recommends against flushing or throwing away ticks removed from dogs and cats. Instead, seal the tick in a container or wrap it tightly in tape, label it with the date and the location on your pet’s body, and contact your vet to ask if they’d like to examine it. Species identification helps your vet assess the risk of diseases like Lyme, ehrlichiosis, or Rocky Mountain spotted fever.
If your pet has multiple ticks, save at least one or two of them and dispose of the rest in rubbing alcohol (assuming your vet doesn’t need all of them identified). Use fine-tipped tweezers for removal, grasping each tick as close to your pet’s skin as possible. Grabbing a tick by its swollen body can squeeze infectious fluids into the bite.
