Musca domestica bait is a component of an insect trapping device EC Fly trap that lures houseflies into the trap.

The liquid bait, must be applied in the trap to be fully functional (EC Fly trap can be bought separately). 
Using such baits is an economic, environmentally sound approach to either monitor or mass-trap these pests. 
The bait must be added in the trap every 1-2 weeks to keep attraction rates high.

Shelf life - up to 1 year (optimum conditions).
