Pests in my area to worry about?

Canada, Northern Ontario.

For an indoor grow, do we need to worry about pests that much?

Or is this always a problem, no matter where you live? Obviously, if I'm growing mid winter I shouldn't have to worry about much, but summer into fall??

Your biggest worry is pests coming in on clones. Shouldn't be a big problem indoors as long as your neighbor isn't growing outside where plants can send their pest problems in through your air intake... Good luck!
