This Chinese study says it was dispersed through global atmospheric circulation and mentions the liquid and gaseous discharge from nuclear facilities at Sellafield (UK) and La Hague (France) as sources. Russian tests are mentioned as well but they are apparently not the sole or primary source.
100% agree on banning glue traps. Snap traps aren't perfect though. I had to finish off a mighty survivor of one once. The rat was huge. When I heard the rattling in the shed I panicked and grabbed a shovel lying nearby. My mind has erased the memory of what happened next, I just remember the aftermath and being splattered with lots of rat blood. I deeply regret doing that and wish I had let her limp away to an uncertain fate. I stopped setting traps after that and just let them run rampant through the moldy old walls of that place until I moved.
Good. I don't mind the noise since it happens during daytime. Put on headphones and lock in or something. But it's impossible to get good air quality during the day with them running nearby constantly. Always smelling the gas and thinking about the CO content and other toxins you're inhaling.

Google search quality was deliberately harmed to boost ad revenue. Forcing you to search multiple times and refine your query means you see more ads and are more likely to click on them.
