Mosquito Management 101: Larval Management

When standing water cannot be eliminated—such as in rain barrels —targeting larvae can help. Use mosquito dunks containing Bacillus thuringiensis israelensis (BTi): These products specifically kill mosquito larvae without harming people, pets, fish, or beneficial insects like dragonflies.

Adult Mosquito Management: Use with Caution

Spraying pesticides to kill adult mosquitoes is often less effective than people expect and comes with trade-offs.

Pesticides that kill mosquitoes also kill beneficial insects, including pollinators. Take care to avoid spraying when flowers are in bloom, and check beforehand with neighbors who have beehives. Take care if edible fruits, vegetables or herbs are being grown nearby. Never spray on a windy day. Treating for Mosquitoes While Protecting Pollinators. Results are short-lived, as new mosquitoes quickly move in. Treatments can be costly and may harm beneficial insects, including pollinators and natural predators. Some products are toxic to aquatic life, so avoid applying near water. Repeated use can lead to pesticide resistance, making future control more difficult.

Before using any pesticide, always read and follow the label carefully. Remove pet items, toys, and food or water dishes from areas to be treated.
