Mosquito or look-alike?
- No-see-ums: tiny biting gnats near marshes. Screens need a finer mesh. - Mosquitoes: slim, long legs, and a needle-like mouth. - Crane flies: look like giant mosquitoes. They don’t bite. - Non-biting midges: swarm near water at dusk. Harmless, just annoying.
When a bite needs a doctor.
Most bites just itch for a few days. Most people infected with West Nile virus never feel sick. About one in five get a fever, headache or body aches. See a doctor for high fever, stiff neck or confusion. Spreading swelling or an infected-looking bite needs a check too.
Protecting your pets.
Dogs get heartworm from mosquito bites. Cats can too. Ask your vet about year-round heartworm prevention. Change pet water bowls daily. Keep pets inside while a yard spray dries.
What a treatment visit looks like.
Larvicide goes in water you can't drain. Then they spray shady shrubs, where adults rest. Most plans repeat every three to four weeks. A visit usually takes 20 to 45 minutes. The tech walks the yard first. They dump or treat standing water.
Rain barrels and ponds.
- Bird baths: change the water every few days. - Gutters: clear them so water drains away. - Tarps: shake out any that hold rainwater. - Pool covers: drain standing water after rain. - Barrels: cover openings with fine mesh. - Ponds: fish and moving water keep larvae down.
