Bat houses are pretty low-maintenance, honestly—just occasional checks for wasps or damage. Mine took about two months before bats moved in, but once they did, mosquitoes noticeably dropped. Worth the wait, imo... citronella never really cut it for me.
Bat houses definitely sound like a solid mosquito solution—I've never had luck with citronella either. On the topic of low-maintenance eco-friendly upgrades, has anyone here installed both greywater recycling and rainwater harvesting systems? I'm curious about your experiences regarding maintenance and reliability over time. I've worked with rainwater setups quite a bit professionally, and they're straightforward enough, but greywater systems seem to have more moving parts and filtration needs... thoughts?
I've tinkered with both setups, and yeah, greywater systems can be a bit fussier—filters clogging, pumps acting up... Rainwater's definitely simpler. Ever had issues with soap residues messing up your greywater filters?
