Stirge Traps?

[Psychotic Jim]

Stirge Paper?

How about an alchemist making some sort of Fly Paper that works on stirges? Or maybe some alchemical pheremone that makes stirges turn on each other, draining each other of blood?

 

[Hand of Evil]

Simple funnel trap, funnel opening into a cage, mostly used for fishing. The villagers place them at opening into their homes, at night the stirges looking for food enter the trap. The next morning you have stirges.

 

[Ferret]

Perhaps a trail of bloody chicken parts into a small, pitch-soaked outbuilding of some sort. Once the stirges were inside, throw a torch in and slam the door.

You know, you could modify that for an evil-aligned village. Let's say you have a cutpurse in the local lockup. Let's say this lockup is made of stone. Smear the prisoner w/ chicken blood, and throw lots of dead chickens in there. Put plenty of pitch soaked kindling in there too. When the stirges flock to the building, throw in a torch and seal the door. Come morning you have lots of dead stirges and one dead cutpurse.

They can only drink so much, after a chicken they'll just buzz off
