Drive a early 90s Jeep Cherokee to work right now. 50 miles each way. There are less bugs.

Many places have mosquitoes commissioners. An elected official for such.

Note back in that time period though some areas such as Florida had a giant population of love bugs. They were an attempt by us to reduce mosquito population. The love bugs eat mosquitoes so they figured let's breed and release a bunch of them to kill them off. It backfired, the population didn't decrease much and the love bugs popped up twice a year in large numbers for about a decade, and slowly died out. (I'm sure some still exist, but they don't plague the areas in such large numbers anymore)
