I must buy a stock.
Note: I use it only topically and sporadically.
I already made a stock (imidacloprid is only thing that works when I get mealy bug infestations) because the Netherlands is far ahead of the EU as a whole in this area. Since 2014 many chemical pesticides are difficult or impossible to find. All neocotinids and a bunch of others were banned for sale or use (professional and consumers) in the country.
