A tool, substance, or person that removes ticks; a device or agent used for deticking animals or surfaces.
From detick + -er 'one who does or tool that does.' The -er suffix creates both agent nouns and instrument nouns in English.
Detickers range from simple tools like tick tweezers to chemical treatments to even guinea fowl (birds that eat ticks)—farmers have created remarkably creative solutions to this ancient parasite problem.
