You need to clean it regularly. Otherwise, it attracts mice and rats, and other rodents. Besides, everything starts with the insects, and then rodents come. I had one in my artificial pond at my house. Once, we left home for more than 3 weeks in a row. Obviously, the trash reservoir was filling up. When I came back, I noticed a lot of mice and rats eating from there. That looked disgusting. Luckily, I found this site —
