There are more than 120,000 species of flies throughout the world, including house, fruit, sewer, and cluster flies. Flies can transmit disease by picking up pathogenic organisms and depositing them on human and animal food. Flies are generally attracted to decaying plant and animal matter, are most abundant in late summer and early fall, and can present large infestations quickly. You can help avoid flies by removing trash and recycling regularly and keeping them in tightly sealed containers, keeping kitchen surfaces clean, and using fine mesh on doors and windows.
If you must treat your home for flies, you should prepare as follows:
- Remove everything from the lower kitchen cupboards (from the counter top down). Place these items on the counter or table. After treatment, do not wash the shelves, simply line them with new paper, either shelf-lining paper or wax paper before putting the dishes or food product back. This will provide a layer of protection between the pesticide and your dishes and/or food product.
- Keep your kitchen very clean.
- Clean all surfaces, including between counters and appliances.
- Keep garbage, recyclables, and compost in tightly sealed containers. Empty daily.
- After treatment, everyone must be away from the home for a minimum of 4 to 6 hours. If anyone in the home is pregnant or nursing, less than 1 year of age, or having severe allergies or respiratory problems, these people should stay away for a longer period of time, generally 24 hours.
- All pets must be removed from the home for a minimum of 4 to 6 hours, except for birds which should be removed for 24 hours. If you have fish tanks you should cover the fish tank with plastic, a towel or a sheet and unplug any fish filters as they pump outside air into the water the fish live in.
