This is what the Aussies are starting to do with tick removal.
"Australian experts and ASCIA (the Australasian Society of Clinical Immunology and Allergy) now recommend you kill the adult tick on your skin with a freezing product such as Wart-Off Freeze or Elastoplast Cold Spray. These sprays contain ether which freezes the tick, thus immediately killing it and preventing it from injecting its saliva or regurgitating its contents into you." http://www.mydr.com.au/first-aid-self-care/tick-removal
"Perhaps the safest method to remove ticks is with a can of freeze-off wart remover, available from chemists. Follow the instructions and spray the remover on the tick, freezing it solid and killing it. When the tick is frozen solid you can easily pull it off with your fingers, and there is no danger that you will squeeze its stomach contents back into your skin." https://growyouthful.com/ailment/tick-bite.php
Starting fluid also has ether in it. I don't have a can of Wart off in my truck but I do have a can of Starting Fluid. I'll try it out if either I or the dogs get ticks. So far we've been lucky.
