Just curious, why would you bother removing ticks from the carcass ? They die soon after deer is shot and cools down or is placed in a fridge, or the animal is skinned and skin disposed of ! In answer to the question though, I stalk on three totally diverse areas, typical Scottish Borders forestry, Lake District valley with mixed woodland/pasture and mixed arable/woodland in the Trough of Bowland. Only one of these areas have I experienced numbers of ticks, the Scottish Borders! However, this year I have noticed ticks on almost every deer I've shot in the 'Trough' where previously they were almost exclusively 'tick free'!
