Here is more information and there are no easy answers. Perhaps you can talk to your neighbor about the situation regarding possible removal or restricting the spread (installing barriers and cutting back.) Here is a short video on the subject https://youtu.be/Qf7S80itdso

For barriers you would have to contact local landscape companies that deal with bamboo and/or removal. We do not know if there are any regulations in your county or homeowners assn. You can check above.

Refer to our webpage for additional information and resources on bamboo removal. https://extension.umd.edu/hgic/topics/bamboo
