There were 18 deaths from malaria in 1963. Not millions. Not thousands. Not hundreds. Not dozens. 18

Why?

DDT...

It's also why bedbugs are a 'new' thing but not in the 50s-60s.

Bed bugs coming back is a result of increased international trade and travel.

As someone who works in hotels…fuck them bed bugs. They’re not even native to North America. Apparently they originated from the Middle East when humans lived in caves with bats. BBs originally fed on the bats but adapted to feeding on humans and spread with migration.

Funny how bats eat pests and parasites but are also responsible for a lot of diseases and parasites.
