The mosquito roast

Dear Agony Akka, I am a resident of Chennai since last five years and each year the mosquito menace is getting more and more out of control. In public places I find myself scratching and swatting my body in various awkward places. My arms and legs are beginning to be filled with scabs and red bite marks. Eating buffet dinners is already a difficult task and when these are held outdoors, it becomes impossible — I have to balance plate in one hand, cutlery in the other, and then the mosquitoes begin biting and I have no hands left to swat them. Two days back we went for socially distanced dinner to a neighbour’s house and whole evening I spent swatting mosquitoes and not being able to focus on the chitchat. When we came home, my husband told me it was bad manners to kill mosquitoes when you are a guest. Is this true? Are there any etiquette rules regarding mosquito problem?
