What is the recommended cleaning frequency for dumpsters and other containers when flies are present?

• A. Daily
• B. Twice per week
• C. Weekly
• D. Monthly

Answer: (B)

Controlling flies starts with eliminating their breeding sites, and dumpsters and other waste containers can be hotspots if they’re not kept clean. When flies are present, cleaning these containers twice per week helps because regular removal of food residues, moisture, and odors disrupts breeding and reduces attraction, making it harder for fly populations to establish themselves. Daily cleaning can be more than what’s practical for many operations, while weekly or monthly cleaning allows residues to build up and odors to attract more flies, increasing the problem. In addition to cleaning, keep lids closed, use liners, and scrub and sanitize the containers during each cleaning.
