Protecting the people, businesses & the environment of LA County. - https://linktr.ee/lac_acwm Established in 1881, our Department protects consumers, the integrity of the marketplace, the health and safety of residents, and improves the quality of the environment through the enforcement of Federal, State and local laws and regulations. Our variety of services is unparalleled in other counties throughout California. Our programs provide leadership and direction in the successful early detection, exclusion, and eradication of dangerous, invasive insect and plant pests; enforcement of laws and regulations regarding safe pesticide use; clearance of weeds, brush, and debris from vacant land to reduce fire hazards; inspection and verification of accuracy of scales, meters, price scanners, and quantity labeling on packaged goods; and the operation of a metrology laboratory. These programs protect the marketplace from unfair competition and a loss of confidence, consumers from fraud and increased food prices, the environment from increased pesticide application and pesticide mishandling, and the agricultural industry from increased costs for pest control.

Did you know that transporting firewood can also move invasive pests?🪵​

Bringing wood from outside county lines (or more than 50 miles) can unintentionally introduce an invasive pest that can cause major damage to local trees and agriculture.​

Getting your house fumigated for termites soon? Here’s what you need to remove before the fumigators arrive:​

🐶 Living things: people, pets (including fish and fish tanks) and plants.​
🍓 Food unless it's double-bagged and sealed in fumigation bags, or stored in glass/metal bottles, cans or jars with the original manufacturer’s air-tight seal intact.​
💊 Medicines unless sealed in special fume-bags.​
🛏️ Mattresses (except waterbeds), box springs and pillows if they're completely enveloped in waterproof covers. If covers can be removed, these items can remain in the house.​

ACWM inspects fumigations in LA County to ensure safety of residents, those administering pesticides and the environment.​

Unsure if a specific item can stay or should be removed? Visit the link in our bio to learn more about fumigation preparation and connect with your licensed fumigator with any questions.

In July, our Detector Dog Team was invited to make a special presentation at the LA County Board of Supervisors Community Services Cluster meeting at the Kenneth Hahn Hall of Administration and give an inside look at how our staff protects LA County from invasive
pests. ​

Chief Deputy Max Regis and Deputy Agricultural Commissioner/Sealer Jordan Petersen introduced the program before handlers and their canine partners demonstrated obedience and scent detection skills they use in the field, including a line search to locate oranges concealed in an unmarked parcel. ​

Following the demonstration, Board Deputies and staff enjoyed an intimate meet and greet with the team and their furry inspectors. Thank you to the County Board of Supervisors for having us and acknowledging the outstanding impact of ACWM's Detector Dog Team Program in helping keep invasive pests out of LA County!

Detector Dog Harper was on the case! 🐾​

ACWM's four-legged partner Harper recently alerted inspectors to an unmarked package containing Palmyra palm plants suspected to have been illegally imported from China. This discovery triggered a joint investigation with the United States Department of Agriculture's Smuggling Interdiction and Trade Compliance Office that uncovered an additional 10 noncompliant boxes of plant material.​

Early detection starts with a trap in a tree! 🌳​

Ongoing trapping allows ACWM inspectors to identify potential invasive pests before they become widespread. The traps pictured here allow us to detect invasive fruit fly species so we can help protect locally grown produce and agriculture well beyond county lines. ​

If you see a trap in your neighborhood, please leave it in place so our inspectors can continue their monitoring efforts. For more information on traps, click on the link: https://acwm.lacounty.gov/did-we-leave-a-trap-in-your-tree
