Flytrap

Flytrap, also called fly bottle is a traditional trap for insects. Made of glass, with squab shape, tapered to the top. Through the hole left at the bottom, flies, allured by sweet scent of liquid poured in flytrap, get into the vessel where they stuck and finally drown unable to get out.

Flytraps were in use on Polish lands since 19th century for the beginning of 2nd World War.
