Ladybird beetles are natural predators, and they eat aphids, fruit fly larvae, mites and scale insects. Instead of immediately using pesticides to kill aphids, try allowing several aphids to survive on your garden plants. Keep bird feeders and baths cleanDuring the summer period, many birds rely on bird baths and feeders for their daily needs. Bird baths must be refreshed with fresh water often to provide birds with clean drinking water and places for bathing. Water plants in the early morning or late evening to reduce water loss through evaporation and help plants make better use of the moisture.
