Tick-Search & Destroy solution.

As many owners of pets in the world know, Ticks are dangerous to us and our pets. We use different chemical or natural repellent to fight the danger.

In reality not many have worked so I thought instead of sitting and waiting, why not make a chemical solution (ecological and human/pet friendly) which connects with biochemical trace of a Tick, and makes a reaction in form of colouring the trace (colour should be strong so it can be seen in fur or hair).

The reaction should stay active ( dissipate after) for lets say 5 minutes so you can easily spot and destroy the Tick, saving yourself or your pets.
I imagined that stronger the biochemical trace is (I presume on and around the Tick) the stronger would be the colouring reaction, so you can see where he started and where is at present time.

Ticks are vectors of a number of diseases, including Lyme disease, Q fever (rare; more commonly transmitted by infected excreta),[4] Colorado tick fever, Rocky Mountain spotted fever, African tick bite fever, Crimean Congo hemorhagic fever, tularemia, tick-borne relapsing fever, babesiosis, ehrlichiosis, and tick-borne meningoencephalitis, as well as bovine anaplasmosis and probably the Heartland virus.[5] Some species, notably the Australian paralysis tick, are also intrinsically venomous and can cause paralysis.
