Pests ( that is higher organisms not micro-organisms) need to arrive along with seeds in some minimum numbers so as to proliferate and become a threat. I disagree about regulations that loose sight of the ammounts implied. Ten seeds inside a glasine envelope doesn't seem to me threat to anything, specially if there are no visible mobile companions. A single bug is no threat, not even two or three. Pernicious insects or other arthropods can easily enter a country along with bulk transport of goods. I doubt that serious threats come via seed exchanges. What worries me is the widespread incompetence of solving the problem, instead of simply banning. It is easy for the bureaucrat but creates many other problems, not only there but elsewhere too. Bureaucracies copy each other quickly- we've seen it during the pandemic- but are quite inept in dealing with problems itself, when the magnitude is so negligible as a seed ex packet...
I'm of the kind that distrusts the over-zealous governments, they end up by backfiring at what they are meant to protect.
