Pests to know in Cedar Rapids
Termites in Cedar Rapids
- Iowa State University Extension says termites are more common in the southern half of Iowa, yet have been reported in almost every county, with infestations that are spotty and widely scattered.[1]
- ISU Extension's termite distribution notes say some northern Iowa counties, especially those with major urban areas and major rivers, have moderate to high levels of termite activity.[2]
Invasive species reported here
The City of Cedar Rapids says emerald ash borer is widespread in its urban area, and the city is removing all parkway ash trees; owners handle ash trees on private property.[7]
Climate

Public agencies that handle pests
- Linn County Public Health reports it is seeing a rise in tick-related issues and recommends repellent and body checks after time outdoors to prevent tick bites.[4]
- According to Iowa HHS, animals in Iowa are infected with rabies every year, and wild animals, especially skunks and bats, are the ones that most often get it.[5]
- Iowa State University's Medical Entomology Laboratory has run Iowa's mosquito surveillance program since 1968 with Iowa HHS and the State Hygienic Lab, tracking West Nile virus and the spread of Aedes albopictus.[6]
Local rules and responsibilities
Cedar Rapids Code Enforcement can placard a property for code violations, and being vermin or rat infested is one of the listed reasons.[8]
Hiring a licensed company
- When termites are found or suspected, ISU Extension advises asking at least three companies licensed by the Iowa Department of Agriculture and Land Stewardship for inspections, written estimates, and references.[3]
- The Iowa Department of Agriculture and Land Stewardship's Pesticide Bureau handles pesticide misuse complaints; an incident report must be filed within 60 days of the alleged damage.[9]
Free local help
To help prevent subterranean termites, ISU Extension recommends keeping mulch and landscaping at least 6 inches from the house foundation and stacking firewood several feet away from the structure.[3]
Through the year
- Winter to Spring
- In Iowa, termite swarmers most often emerge in mass flights in spring, and ISU Extension notes termites are generally not active during the winter.[1]
- Spring to Fall
- Linn County Public Health says ticks can turn up any time of year, but in Iowa they are active from March through November.[4]
