Integrated Mosquito Management
Integrated Mosquito Management (IMM) uses multiple methods together for long-range, environmentally responsible mosquito control. Rather than relying on a single approach, we combine surveillance, prevention, biological controls, and targeted treatment based on what the data tells us.
How IMM Works:
- Surveillance — We identify mosquito species and track larval and adult population levels throughout Salt Lake City. This drives every decision that follows.
- Physical Control — Where practical, we modify breeding sites, manage water sources, and reduce mosquito habitat directly.
- Biological Control — We stock ornamental ponds with Gambusia affinis (western mosquitofish), a natural predator that reduces larvae without chemicals.
- Chemical Control — When other methods aren't sufficient, we apply pesticides to specific breeding areas or adult populations. It's targeted, not blanket.
- Education — We work with the public to reduce breeding sites at the source.
Why Mosquito Control Matters
Salt Lake City has abundant water sources near homes and businesses — ideal mosquito habitat. Without active control, mosquito populations would make outdoor life uncomfortable and increase disease risk.
This is a maintenance program, not an eradication effort. The goal is reducing mosquito populations to a tolerable level while protecting the environment — striking a balance that allows comfortable, healthful human existence.
Our Focus: Larvae First
We prioritize larval control because:
- Larvicides target mosquito biology specifically, with minimal impact on other aquatic life
- Treating breeding sites is more effective than pursuing flying adults
- Control stays localized, reducing environmental footprintAdult mosquito control is used only when surveillance data shows it's necessary for public health.
