A home made fly trap is any device designed to capture and optionally kill flies using materials typically found in a home, such as a plastic bottle, sugar, and vinegar.
These traps are relevant because flies are common household pests that can transmit diseases and contaminate food. Home made fly traps are an inexpensive and effective way to control fly populations. Historically, an ancient Egyptian papyrus describes a fly trap made from a clay cone with holes in it, baited with dates in order to catch the insects.
