To effectively catch loose Drosophila, various baiting methods can be employed. One popular technique involves using beer in a beaker, which attracts the flies and leads to their drowning. Another effective bait is a mixture of yeast, water, and banana. For larger infestations, placing flypaper near the trap can help, although caution is advised to avoid getting hair stuck. In cases of significant fly escapes, creating a passive trap from a plastic bottle by cutting the top off, inverting it, and sealing the edges can be useful. This trap can be baited with fruit juice or bits of fruit. Notably, Drosophila are particularly attracted to Scotch, as experienced by a bartender who faced challenges with flies infiltrating liquor bottles. Ultimately, maintaining proper sealing on bottles is crucial to prevent infestations.
