The Montreal metro system is pretty old by now. The construction of the first two lines - green and orange - began in 1962. That's exactly 56 years ago.\nREAD ALSO: The Names Of Montreal's 68 STM Metro Stations Explained\nIt's no wonder that some of these ancient metro stations require constant maintenance, upkeep, and renovations. And as a result of that, we often find some not so cute urban wildlife popping out of the dark hidden corners.\nHere are the metro stations that are notoriously known for frequent rat, cockroach and mice spottings, and just general grossness. If you're ever in a station and you spot something fuzzy running around, don't forget to grab your phone and let us know! We are always happy to share this skin-crawling news with the rest of the city.\n1. Guy-Concordia Metro\nView this post on Instagram passing through #cuseenby A post shared by HJH (@incmmnsra) on Jan 24, 2018 at 10:42pm PST\nFor those of you who are going to or have graduated from Concordia - or anyone who spends a significant amount of time here - you will know that visiting this Metro station every day also means saying hello to its little sub-terranean dwellers, the cockroach. At a certain point, back around 2012 before the stations had been renovated, the infestation was particularly bad, and cockroaches were seen on the regular. Most likely caused by the food courts above the station, Guy Concordia was hit hard with this little creepy crawlies. At this point in time, the conditions seem to have improved, but take a closer look at the leaky ceiling cracks and the crumbling walls and then you might not be so sure anymore.\n2.

Constructed of raw concrete and steel, looks clean to me! But think again. Many commuters have spotted mice scurrying around the floors of this West-side metro station, and we have documented video proof. In my opinion, I would rather see a cute furry little mouse than a cockroach, but to each their own.\n3. Sauve Metro\n@oldsofficialembedded via\nAesthetically speaking Sauve metro is pretty meh. Personally, I don't spend much time at this North-side metro station, but word on the street is that if you look carefully down at your feet, especially in the winter months, you may see some larger furry critters running around. When it's cold outside, rats love to seek refuge in the warm and toasty walls of the metro walls, especially metro Sauve.\n4. Beaudry Metro\n@shadesofindigoembedded via\nAlthough the mile-long conveyor-style escalator makes for a great photo-op backdrop, Beaudry metro has been called "a sewer with a coat of paint on it", and they are not wrong. I remember working in the Village a few summers and having to visit this East-side metro stop almost every day. I can conjure up this very distinct smell of the metro station in my head just by thinking about it. This metro station most definitely has its fair share of urban wildlife calling it home.\n5. Beaubien Metro\n@zecarpioembedded via\nBeaubien Metro has undergone quite a bit of construction over the past years. At a certain point back in 2016 the station was completely shut down for huge renovations, and the station will also be shut down AGAIN this fall 2018 for more reno. And you know what goes hand in hand with construction? That's right, rats. Personally speaking, I have first-hand spotted a rat at this Metro station, so let's hope that all these fancy renovations are going to eradicate the problem once and for all.
