I love my garden, it is heaving with all sorts of wildlife including squirrels, wood pigeons and the odd engine,old motorbike ect. I dont have a problem with them. I imagine its the garden gnome, fake wishing well types with their poxy twee gardens c/w neat borders that consider these creatures to be pests 
Chill out and leave the poor buggers alone!

Squirrels are primary carriers of tick fever, powassan virus and rabies.
Tick fever is a virus that results in, obviously, a fever, chills, headache, eye pain, muscle pain, nausea and vomiting. Tick fever can be a severe illness, especially in children and the elderly.
Powassan virus can cause severe encephalitis in humans and has up to a 60 percent fatality in squirrels. Infected humans may experience sleepiness, disorientation and become semicomatose.
Rabies, a virus, progressively paralyzes and can kill any mammal, including humans. Rabies is generally contracted through contact with an infected squirrel through biting. Though humans should avoid contact with any squirrels, if a squirrel seems especially fearless around humans, it could be infected
