For every 100 tiger mosquitos in #Lombardy, #Italy 🇮🇹, there are only 25 in #Ticino, #Switzerland 🇨🇭. Why?
Swiss #mosquito researchers use Lombardy as the "no intervention", control sample, when comparing results
Swiss controls work:
- Remove breeding sites (stagnant water)
- When you can't, treat water with larvicides
- Reserve #insecticides for periods of high health risks
Ever been in summer in Southern Swiss lakes? You know that it works.
