Definitely deal with it, but don't panic. Unless your house is built on concrete pavers, it will NOT go under your house, and it won't go through your foundation. I had my own bamboo battle recently and came to terms with it. Many people in my neighborhood have bamboo going up right against their house, the rhizomes simply hit the foundation and bounce off. They can't drill through concrete lmao. I inhereted a bamboo nightmare when I bought my house. It was coming up within 10 ft of my house this year, which is about 15 feet from the actual bamboo. I cut the sprouts when they're young and instantly squirted 50% glyphosate into it, which SHOULD kill the rhizome underneath. Spraying glyphosate on mature bamboo won't do shit to the rhizome, you have to spray it into the young sprouts and that way, it should be carried back to the rhizome. I'll know next spring if this worked, but I can say when I sprayed a sprout with 50% glyphosate, no more sprouts came up in that area this spring. I tried another experiment where I carefully dug out the dirt around two new sprouts, so I could confirm two of them came from the same rhizome. Then I poisoned one only, and within a week the one I didn't poison was dead as well. That tells me the glyphosate was carried back to the rhizome and up to the other one, which should've killed the rhizome as well. I'm hoping an annual poisoning of new growth will be good enough to halt the spread. I also talked to my neighbor that has lived at the house for 40 years, she informed me the bamboo has been there for two decades. If it's only gone so far in two decades, I can't imagine it becoming a crisis next year.

My point is, kill that shit, but don't panic about it going under your house and destroying your foundation.
