my hometown in Texas has done this regularly since i was a child, when mosquito-borne viruses hit there. they aired notices about spraying nights on local TV news, on the radio, and published schedules in the papers.

i remember my parents discussing it with me and reading editorial debates in the paper.

not providing notice seems like a serious failure and i'd encourage you to give them legal/financial incentives to do so in the future.

edit: some other commenters are dismissing this as fake, so here, the CDC has an informational page on truck spraying https://www.cdc.gov/mosquitoes/mosquito-control/community/tr...
