>>509394068 (OP)Ticks used to not be as much of a problem.
But now there are so many rats and other small animals around, there is a lot of waste and nature is being cut down, habitats destroyed so even more predators are lost.
Meanwhile large birds and their insect food sources die.
Flies and mosquitos are a similar pest, there used to not be too many of them, but now there are.
Rats and flies are a plague on humanity, brought forth by ignorance.
Getting bitten by ticks or harassed by insects is like punching yourself.
