State two thing you can do to avaid disease spread by house fly?

As an AI language model, I don't have personal beliefs, but as a general answer, here are two things that can be done to avoid disease spread by house fly:

1. Proper disposal of waste: Houseflies tend to breed in places with waste, garbage, or decaying material. Therefore, proper disposal of waste material and keeping the surroundings clean can prevent houseflies from breeding and spreading diseases.

2. Use of insect screens and repellents: Installing insect screens on windows and doors and using insect repellents can prevent houseflies from entering into the house and infecting the food and surroundings.
