I had a mouse issue but it's been a couple weeks without activity so I decided to do what terminex recommend and vacuum all the droppings and replace the vapor barrier. I now have an appt for them to come fog my crawlspace with a deodorizing bleach type thing.
So anyways just wanna give some advice if anyone else wants to DIY instead of pay $3k for the service. My crawlspace is about 950 sq ft and has 3 separate areas that require crawling over and under pipes and foundation.
TL;DR: it's hard but doable if you're up to a medium challenge
Wear a damn mask that is P100 or better, spritz the droppings with bleach/water before vacuuming (hepa filter on vacuum). I dono about where y'all live but we've had a couple cases out in my county/neighboring counties of people getting hantavirus.
The old plastic barrier takes up a lot of space when you remove it even after trying to roll it up and make it as compact as possible it still filled up my trash bin for the week plus a little bit. Try and keep all mouse shit on the plastic as you roll/fold it up so it's not on the dirt after you removed the plastic.
Be ready to find all sorts of random things the construction crew left behind. There was trash from all sorts of crap along with homes the mice had made for themselves. Once I removed the plastic I then went back with 2 garbage bags to clean up all the trash that was chilling there.
Depending on the size of the crawlspace it's quite an arm workout. I can barely squat in mine and it's about 3ft high, so most of my time was spent in the push-up position or girl push-up position. I'm reasonably in good shape and it was quite a workout doing that for about 5 hours. But having to move around like Catherine Zeta-Jones around the lasers in Entrapment is one hell of a workout lol.
Then putting the new plastic down I went with 10 mil white and I like how it makes it easier to see as the headlamp reflects more than it did with the old black stuff. I measured the length of each spot then cut it outside on the patio and brought all those sections down at once but already cut up which made it a lot easier to unfold since most pieces were 10ftx25ft 'ish. Still unfolding it in limited space is not easy and trying to move it around while sitting on it takes a bit of thinking. Best way I found was to put my hands on the foundation and move it around with my feet when getting it into the final position.
As always though it feels great to DIY something than to pay for it.
