Most economical from a time and money standpoint is lead poisoning. Second choice is conibear traps which are equally lethal but quitter if HOA forbids first option. Live traps as last resort because they are expensive, a lot of trouble and require skill and a lot of time to get the job done. Some may suggest hot sauce or black pepper which really add flavor if you plan to eat them.

Seriously, once they begin chewing, they will just move to siding if you succeed in discouraging them from destroying vents. If they every get inside attic they will nest and raise more that run through attic all hours of day and night.

Thankyou! What are conibear traps???

Maybe install some wire mesh/hardware cloth over the vents. Hopefully they will lose interest if it's difficult to chew through. They can be determined buggers. I had some chew through a metal reinforced bird feeder, it took them about 4 years but they eventually got through.
