Pest Control
Pest control is the process of minimizing or removing a wide range of undesirable insects and other pests from causing harms to people. The Program provides individual consultation about the control of rodents and other public health pests. This includes a distribution of rodent control information in neighborhoods associated with improper solid waste handling, storage and disposal practices.
Rodents and Insects
The Snohomish Health District provides information on the control of rats and other vectors. If you need to file a complaint please complete the Complaint Form For Field Investigation and send it to:
Environmental Health Division
3020 Rucker Avenue, Suite 104
Everett, WA 98201-3900
OR email the completed form to:
Hantavirus Pulmonary Syndrome
The Sin Nombre virus (SNV), which causes Hantavirus Pulmonary Syndrome (HPS) is carried by deer mice. Deer mice are found throughout Washington, particularly in rural areas. The Sin Nombre Virus is excreted in the deer mouse saliva, urine and feces. SNV is transmitted when people inhale aerosolized virus during activities that may disturb rodent nests or droppings, such as sweeping.
The incubation period for HPS is one-six weeks; nonspecific symptoms may appear within one-six days of infection. Early diagnosis and management of HPS is critical for survival. HPS is fatal if left untreated.
Snohomish Health District does not bait or trap rats. Additional information on rat control is listing below:

Lyme Disease
Lyme disease infections occur when an infected tick vector bites a person. There are two species of ticks that are associated with Lyme disease, they are Ixodes scapularis and Ixodes pacificus. Lyme disease occurs primarily in three distinct regions of the United States. These regions are the Northeast, Midwest, especially Wisconsin and Minnesota, and less commonly the West Coast.
People of all ages may be affected; however, children 5-9 years of age and adults 45-54 years of age seem to have the highest incidence of Lyme disease.
If you believe an infected tick has bitten you, please contact the Communicable Disease Department at 425.339.5278 or at For more information on Lyme disease, please visit the link below.

Pest control is an important part of routine health inspections. While no food establishment wants cockroaches, these pests are a part of daily life. The health inspectors in the Environmental Health Division work with food establishment operators to implement pest control maintenance plans.
Cockroaches are disgusting bugs; however, besides being creepy they may also cause health problems. Cockroaches can expel "roach dust". "Roach dust" is particles such as droppings or body parts that become aerosolized. These particles may then trigger asthma in people who are sensitive.
