Most of the world uses WhatsApp, and it does not matter if you have iPhone or Android. Are you in the USA? I hear it is the only country where people use apple messages so much that it matters.

In the region where I leave it would be impossible to not have mosquitoes around, the conditions are just good for them, but I have an electric zapper that is shaped like a tennis racquet and I can zap them as soon as I see them inside the house. I also do the chemical fumigation now and then, but for the most part I use the electric zapper. It is very common in countries and regions where mosquitoes are a pest.
