The weekly water walk.
- Tree holes: fill them with sand. - Gutters: clear leaves so water drains. - Saucers and pots: empty them or add sand. - Toys and buckets: store them upside down. - Tarps and covers: pull them tight so water runs off. - Birdbaths: change the water twice a week. - Pet bowls: refresh daily. - AC drip lines and downspouts: make sure water drains away.
Avoiding bites.
- Timing: tiger mosquitoes bite by day; house mosquitoes at dusk. - Repellent: DEET, picaridin, IR3535 or oil of lemon eucalyptus. - Clothing: long sleeves and pants help at dusk. - Fans: a patio fan keeps weak-flying mosquitoes away. - Screens: repair holes in window and door screens.
