The Compton Creek Mosquito Abatement District is an independent special district committed to protecting the public’s health, safety and welfare from mosquito-borne diseases. In fact, we have been performing this service, protecting public health, since 1927, when the residents of the City of Compton, realizing that mosquitoes were having an adverse effect on the lives, elected to form the Distric

t and alleviate the problems with mosquitoes. Now covering 12.5 square miles and protecting close to 100,000 citizens, the District is funded through tax dollars and provides free services for mosquitoes and all of the other related items involved in mosquito control.

August Wrap — Compton Creek Mosquito Abatement District 🎹🦗

As August closes, here's a look at where things stand.

What happened this month:
✅ West Nile Virus remained active in LA County throughout August at elevated levels relative to recent years
✅ CCMAD field teams operated at peak capacity — increased
inspections, treatments, mosquitofish distribution, and resident
response
✅ Compton Unified opened August 13 — back-to-school mosquito protection guidance reached Compton families across all three platform.
✅World Mosquito Day — August 20 — marked 130 years since Sir Ronald Ross's discovery that mosquitoes transmit disease
✅ 21 social posts across four content phases reached residents on
Instagram, Facebook, and Twitter/X

What hasn't changed:
El Niño conditions continue. Mosquito activity in Southern California may hold at meaningful levels through October. WNV risk doesn't disappear on September 1.

What's coming:
CCMAD will continue posting through the active season. September content will cover the extended season, late-summer prevention, and District field updates.

Thank you to everyone who shared a post, reported standing water,
called for mosquitofish, and spread the word in your neighborhood this month. Every share is a household that's better protected.

We'll be here. 310-933-5321 | comptoncreekmad.org

Late August Update: What El Niño Means for the Rest of the Season 🍃🦟

The back-to-school rush is settling in. The days are getting incrementally shorter. Summer feels like it's beginning to wind down.

Here's the update on where mosquito season stands:

El Niño conditions have not changed. Forecasters are continuing to project elevated temperatures and humidity across Southern California through September and into fall. Culex mosquito activity, which residents typically expect to decline with August, may hold at meaningful levels through October this year.

West Nile Virus risk in LA County doesn't have an end-of-August expiration date. The disease surveillance data and field conditions we're monitoring at CCMAD don't change based on the calendar.

What this means for your household:
💧 Continue the weekly yard check through September — standing
water remains a breeding source
🧴 Keep repellent in your routine for evening outdoor activities through fall
📞 Continue reporting standing water in your neighborhood: 310-933-5321

We'll keep you updated as conditions change. When the season genuinely winds down, we'll tell you.

CCMAD Offers Free Mosquitofish — Here's How to Get Them 🐟🦟

If you have an ornamental pond, fountain, garden water feature, or any body of standing water that can't be easily drained, Compton Creek Mosquito Abatement District can help — at no cost.

We provide free mosquitofish (Gambusia affinis) to residents
throughout our service area. Mosquitofish are small freshwater fish — typically 1-2 inches — that feed voraciously on mosquito larvae. A properly stocked pond or water feature can control mosquito larvae naturally, without chemicals, indefinitely.

Why mosquitofish work:
🐟 They consume hundreds of larvae per day
🐟 They're a naturally occurring species compatible with most
ornamental pond environments
🐟They require no feeding or special care beyond what a basic pond already provides
🐟 They're an EPA-recognized biological control method

This is especially relevant right now. El Niño conditions are extending breeding windows — standing water that normally dries out quickly is persisting longer this summer. If you have a water feature that's been sitting untreated, this is the right week to call.

To request free mosquitofish: 310-933-5321. One call, no cost.

Mosquito Season and Your Pets: What Compton Pet Owners Need to Know.🦟

When we talk about mosquito protection, the conversation usually focuses on human health. But mosquitoes are a veterinary health concern too — and August is a good time to make sure your pets are protected.

Heartworm disease (Dirofilaria immitis) is transmitted exclusively by mosquitoes. An infected mosquito deposits larvae during a bite, and the larvae develop into worms that live in the heart, lungs, and blood vessels of affected animals. Heartworm can be fatal in dogs if left untreated. Cats can also be affected.

Cases of heartworm have been reported in LA County this season. If your dog or cat spends time outside — especially at dusk — standing water in your yard is a health issue for them, not just for you.

What pet owners should do:
🐾 Talk to your veterinarian about heartworm prevention medication if your pet isn't currently on it — this is the most effective protection available
💧Eliminate standing water from areas where your pets spend time outdoors

⚠ Important: Products containing DEET are toxic to dogs and cats — do not apply human mosquito repellents to pets

✅ Pet-safe mosquito protection options exist — ask your vet for recommendations specific to your animal

Myth vs. Fact: Does Mosquito Season End When Summer Does?🦟❌

Myth: "Once summer is over, mosquito season is done.

Fact: In Southern California, mosquito season does not follow the calendar.

Culex quinquefasciatus — the primary mosquito species in our region and the one responsible for West Nile Virus transmission — can remain active and breeding as long as temperatures stay warm enough. In a typical year for greater LA, meaningful Culex activity can persist
through October, sometimes into early November.

2026 is not a typical year.

El Niño conditions are generating warmer-than-usual temperatures and elevated humidity that forecasters expect to persist well into fall across Southern California. The conditions that support mosquito breeding and activity — standing water, warm nights, elevated humidity — will not disappear with August.

What this means for residents:
💧Continue eliminating standing water from your property through September and into October
🧴Keep an EPA-Registered repellent accessible for evening outdoor activities through fall
📞Continue reporting standing water and mosquito concerns to CCMAD: 310-933-532

When the active season genuinely winds down, we'll tell you. Until then, the prevention habits remain relevant.

Why Your Workout Increases Mosquito Risk — And What to Do About It 🏃‍♂️🦟

Here's a mosquito fact that catches a lot of outdoor exercisers off guard.

Mosquitoes locate hosts by tracking carbon dioxide (CO2), body heat, and lactic acid. After physical activity — a run, a walk, yard work — all three remain elevated for approximately 30-45 minutes after you finish.

That means the post-workout cooling-off period — sitting on the porch after a jog, stretching in the yard, walking home from the park — is actually your highest-risk window for mosquito attraction.

El Niño makes it worse: warmer-than-usual evening temperatures this summer mean Culex mosquitoes remain active later into the night than a typical August. The window where your elevated body chemistry overlaps with peak mosquito activity is extended.

What you can do:
🧴Apply repellent before outdoor exercise — don't wait until you're cooling off outside afterward
🚿A shower or change of clothes after exercise before sitting outside reduces your lactic acid and body heat signature
💡 If you're cooling off on the porch, a fan can help disperse CO2 and body heat from the immediate area

West Nile Virus is active in LA County. This is a manageable risk with just a few small adjustments.

What Compton Creek Mosquito Abatement District Does in Your Neighborhood 🚐🦟

Public health agencies are often invisible until something goes wrong. Here's exactly what your district does — and what it means for your neighborhood.

🔬 Water Quality Monitoring
CCMAD tests water sources across our 12.5-square-mile service area
for mosquito larvae. This includes waterways, drainage channels, and
standing water reported by residents. Monitoring data informs where
and when treatment is applied.

💧Larvicide Application
Standing water that cannot be drained — retention basins, drainage infrastructure, water features — is treated with EPA-approved biological larvicides. These products target mosquito larvae specifically and are safe for wildlife, fish, and people.

🐟Mosquitofish Distribution
Gambusia affinis — mosquitofish — are provided free of charge to residents with ornamental ponds, fountains, and water features. These fish consume mosquito larvae naturally, with no chemicals and no ongoing maintenance beyond basic pond care.

📞 Resident Response
When residents call or report standing water, CCMAD investigates and responds. Your reports directly inform our field priorities. If you see standing water in your neighborhood that hasn't been addressed, call us.

📊Disease Surveillance
CCMAD coordinates with LA County and the California Department of Public Health to monitor West Nile Virus activity. When risk is elevated, we issue public health advisories and increase field operations accordingly.

This season, all programs are running at peak capacity. WNV is active. El Niño is extending conditions. We're here.

World Mosquito Day — August 20, 2026 🌍🦟

On August 20, 1897, British physician Sir Ronald Ross confirmed what scientists had suspected but never proven: that mosquitoes transmit malaria. His discovery — made while studying in India — laid the foundation for modern mosquito control and is credited with saving tens of millions of lives over the 130 years since.

Today, August 20, is World Mosquito Day: a global recognition of that discovery and the ongoing work of mosquito control agencies around the world.

In Compton, that work looks like this:

🔬Water Quality Testing — monitoring waterways and standing water sources across our 12.5 square mile service area for mosquito larvae activity.

💧 Larvicide Application — treating standing water that cannot be drained with EPA-approved biological larvicides safe for wildlife and people.

🐟 Mosquitofish Distribution — providing free Gambusia affinis to residents with ornamental ponds and water features that can't be drained

📞 Resident Response — answering calls, investigating reports, and addressing standing water sources across the service area

🚐 Field Operations — teams in the field every week through the active season

This season is one of the most significant in recent memory. West Nile Virus is active in LA County at elevated levels. El Niño is extending conditions favorable to mosquito activity into fall. The work CCMAD does is active and intentional public health response.

World Mosquito Day Is Tomorrow — Check the Spots You've Been
Missing 🦟📋

August 20 is World Mosquito Day, marking the 1897 discovery that
mosquitoes transmit disease. It's also a good occasion to look at your property with fresh eyes.

Most residents know to check birdbaths, buckets, and obvious
containers. Here are the spots that most commonly get missed — and that CCMAD's field teams regularly find as active breeding sites in residential LA County:

💧Clogged rain gutters: The single most common residential breeding site our teams encounter. Standing water in gutters can accumulate over weeks without being noticed. If you haven't cleared yours this summer, this week is the time.

💧Plant saucers: Drainage from potted plants collects in saucers constantly. They need to be emptied every 5-7 days in warm weather.

💧 Tarps and outdoor covers: Furniture covers, pool covers, grill covers, and tarps all collect water in their folds. Check what's pooling after watering or dew.

💧 Hollow spots in ornamental trees: Hollow depressions in tree trunks and branches hold water for extended periods and are frequently missed.

💧 Alley debris: Bottle caps, cans, cups, and containers in alleys and along fences — small, out of sight, and often holding water for weeks.

💧 Delivery packaging: Cardboard and plastic left outside after deliveries can hold water. Move it inside or to a bin quickly.

Mosquitoes need approximately a teaspoon of standing water and one week to complete a breeding cycle in warm Southern California
conditions.

Evening Sports and Mosquito Risk — What Compton Families Need to Know ⚽🦟

For families with kids in evening sports — soccer, football, baseball, track — August is the month to add one thing to the sports bag routine.

Culex mosquitoes, the species that transmits West Nile Virus in Southern California, become active at dusk and remain active through midnight. Evening practice typically runs from 5-8pm. A child at evening practice is spending 2+ hours outdoors during peak mosquito activity, multiple days per week.

With West Nile Virus active in LA County and El Niño keeping evening temperatures elevated later than usual, that exposure window carries more risk than a typical August.

What to do:
🧴 Add a travel-size EPA-registered repellent to every sports bag
⏰ Apply before practice — not after, when the exposure has already happened
👕 Long sleeves or a light jacket for evening practice add a layer of protection
💧 If your practice field has standing water nearby, report it to CCMAD so it can be treated: 310-933-5321
