You’ve treated your yard, followed the directions, and yet, mosquitoes remain. If you’re wondering why you’re still getting mosquito bites after spraying, you’re not alone.
Controlling mosquito populations in Louisiana’s hot and humid climate is tricky. Effective mosquito control requires more than just spraying.
From hidden breeding grounds to ineffective application, there are several reasons your mosquito control efforts might not be working as expected.
Key Takeaways
• Many mosquito treatments ignore mosquito larvae in standing water.
• Weather and application method can reduce the effectiveness of mosquito spraying.
• Adult mosquitoes can migrate from nearby untreated areas.
• Effective mosquito control combines adulticide, larvicide, and prevention.
1. Standing Water Keeps Breeding Mosquito Larvae
Most homeowners focus on adult mosquitoes, but the real problem is often the water around your yard. Mosquitoes lay eggs in places like gutters, birdbaths, and flower pots. Even small puddles under air conditioners can breed mosquito larvae.
Spraying without removing standing water is like trying to bail out a boat with a hole still in it.
What You Can Do:
Empty outdoor containers weekly. Clear out clogged gutters and refresh water in pet bowls and birdbaths. You can also use a larvicide that’s safe for pollinators and approved by the EPA to kill mosquito larvae before they hatch.
2. The Mosquito Spraying Missed Key Areas
A good mosquito control program uses targeted application methods, like ULV (ultra-low volume) fogging or backpack sprayers. However, if the treatment doesn’t reach areas where mosquitoes hide, such as dense shrubs, under decks, or behind sheds, adult mosquitoes can survive.
At LaJaunie’s Pest Control, our technicians use foggers and precision application to reach shady, humid spots where mosquitoes rest during the day.
If the technician missed these areas, that might be why you’re still getting mosquito bites.
3. New Mosquitoes Are Flying In
Mosquitoes don’t stay put. Even if you’ve done everything right, mosquitoes from neighboring properties, wooded lots, or ditches can quickly move into your treated yard.
Just one untreated yard can reintroduce mosquitoes to everyone nearby. Mosquito control works best when neighbors work together.
Infected mosquitoes spread several diseases, such as West Nile virus, which the CDC continues to monitor closely.
4. The Treatment Didn’t Address All Life Stages
If your treatment used only an adulticide, it may have killed adult mosquitoes but left behind eggs and larvae. Without a larvicide to stop future generations, new mosquitoes can appear within days.
At LaJaunie’s, we use both adulticide and larvicide methods, including our In2Care system, which targets mosquito breeding with a bio-repellent that sterilizes mosquitoes and spreads through standing water sources.
5. Weather and Timing Impact Effectiveness
Mosquito treatments don’t last forever. Rain, sun, and even wind can break down the active ingredients in many sprays. Pyrethroids and pyrethrins, common ingredients in EPA-approved repellents, are especially prone to breaking down in rain, sun, and wind.
If the treatment faded too fast, adult mosquitoes might not have made enough contact with the spray to be affected.
Monthly treatments help maintain protection, especially during Louisiana’s peak mosquito season when heat and humidity are high.
How LaJaunie’s Tackles Mosquitoes After Spraying
At LaJaunie’s Pest Control, our mosquito control services go beyond just fogging:
• Monthly mosquito treatments using a combination of adulticide and larvicide.
• The In2Care system prevents breeding and sterilizes adult mosquitoes.
• Expert guidance to help homeowners eliminate breeding sites like clogged gutters, shady shrubs, and areas of standing water.
Our treatments use EPA-approved materials and consider the safety of honey bees and other beneficial pollinators.

FAQs
How long does mosquito spraying last?
Most treatments last around 21 to 30 days, depending on the weather and application method. Regular service is key to keeping mosquito populations low.
Are pesticides safe for kids and pets?
We use only EPA-registered products and apply them following safety standards. LaJaunie’s also offers alternative systems like In2Care for eco-conscious families.
Do aerial spraying methods work better?
Aerial spraying can treat large areas quickly, but may not be as targeted as on-the-ground treatments. In areas with dense vegetation or high mosquito activity, combining both is most effective.
