Why have we not been able to eradicate mosquitoes completely?
In: Biology
A big problem is that you can’t eradicate mosquitoes in one place. Say Country A manages to totally eradicate a problem species, but there are still mosquitoes of that species in Country B. Mosquitoes from Country B will be able to colonize Country A and re-establish the species. It’s obvious how this could happen if the countries share a land border, but it can happen even if they don’t. We think the Asian tiger mosquito hitched a ride on a shipment of used tires from Japan to the US.
You need to get cooperation between many countries to eradicate a widespread species of mosquito, and that’s not always easy to do.
