Another pesky thing that has turned up in Ontario is Deer Ticks which carry tick-borne infectious disease - lyme disease. They have been found in parts of Ontario and have tested positive for the bacteria that is responsible.
I just finished cutting grass and was cutting along the border of the "wild" parts of the property and caught a tick crawling up my leg before it attached. Fortunately it was just a dog tick and not a deer tick.
With the hogweed and ticks investing your land you are not going to want to leave your house.
