Mosquito-proof your property
HCPHES continues to encourage residents to eliminate mosquito breeding habitats around their property.
- Remove or empty all outside containers that may hold water such as flowerpots, tires and toys.
- Bird baths and pet water bowls should be changed at least twice a week.
- Clean out gutters and make sure windows and doors have proper screening.
- Do not "feed" the storm drains. Sweep up lawn clippings, leaves and tree limbs from sidewalks and driveways and dispose of them properly.
Prevent mosquito breeding in boats
- Cover your boat and store it in a covered place.
- Drain any standing water and make sure the bilge pump is working.
- Turn over canoes, kayaks and small boats to store upside down.
Historically, in Harris County, July through September is the peak timeframe for disease transmission to humans. To reduce the likelihood of being bitten by mosquitoes, practice personal protective measures.
- When outdoors, use an insect repellent containing the active ingredient DEET, Picaridin, oil of lemon eucalyptus, or IR3535 and apply as directed on the label.
- If possible, wear long-sleeved shirts and long pants at dawn and dusk when mosquitoes are most active.
