DO NOT PUT OIL On OR BURN TICKS.
Canada has a major problem with Ticks and if you check on the net you will see several reports by Canadian Vets/Drs detailing what to do to remove a tick, first and foremost is not to put anything onto it, Spirits, Oil etc which will only cause the little varmint to disgorge the contents of its stomach back into the host, the same applies to burning them. Secondly the "screwing them out" therory is dismissed because the Tick is not in anyway "screwed in" its just dug in with I think a barbed mouth, twisting the Tick will do two things, first you will probably squeeze the blighter and again squirt its foul contents into your pet, and secondly, twisting it is much more likely to break off the "mouth parts" which will then fester in the host. The Answer is a gadget called a Tick Spoon which can be bought at a UK Vet or as I did one evening, made quite easily from a plastic medicine spoon in which you cut a short tapered slot in the front edge, slip the spoon under the Tick until its firmly nipped in the slot, and the Tick can then be levered out where it rolls about looking gruesome in the bowl of the spoon, there is no g/tee that you will not have left behind a part of the Tick, but apparently its much less likely. I know all this because last year out little dogs came in from the garden with perhaps 15 Ticks between them, and the Spoon worked extremely well,
