What creatures are attracted to uncovered trash receptacles outdoors?

Uncovered trash receptacles outdoors can attract a variety of pests due to the access they provide to food sources and potential nesting sites. Filth flies, such as house flies and blow flies, are particularly drawn to organic waste found in trash due to their breeding habits; they lay eggs in decaying matter. Rodents, including rats and mice, are also attracted to uncovered trash because it offers easy access to food. Additionally, cockroaches thrive in environments where food is readily available, and trash receptacles that are not covered can provide them with both food and shelter.

The correct answer reflects the fact that all three groups—filth flies, rodents, and cockroaches—are likely to be drawn to improperly managed trash, emphasizing the importance of proper waste disposal to mitigate pest problems.
