Physical attacks, as opposed to what? Chemical warfare?

They’re easy to swat. Two things: They always launch backwards and the react to shadows.

Creep slow from behind. If you have to cause a shadow, move very slowly. They jump into your fist.

Step 1: Get masters in chemistry

Step 2: ???

Step 3: Use your newly invented fly killing gas nuke (harmless to humans and all other non fly life on planet earth, of course) and nuke the entire planet.

                    **PROFIT**

Can confirm. Tried to swat a fly, but the police broke my door instead
