I also watched the video and wondered how it works. I found this video that explains the process. https://esajournals.onlinelibrary.wiley.com/doi/full/10.1002/ecs2.4155#:~:text=Tick control tubes contain permethrin,these tubes for tick control.Thanks for posting that.
I had never heard of those "Tick tubes".
I'm gonna make some up and try it out.
I also considered using cardboard tubes, but I believe a better solution would be to use central vacuum plastic tubing cut into the same length as a toilet paper tube. I will also drill a hold in the middle of the tube that goes through to the other side of the tube, and use a 16 penny nail to keep it in place. I can see the cardboard tube being chewed up for nesting material along with the cotton balls. It will also eliminate the cardboard tubes getting water soaked rendering the cotton balls useless.
One thing that I also think about is rodent control killing off the mouse population. If you have a rodent control method in use, you could in theory knock down the mouse population so that the tick population will thrive on the remaining mice.
