Chiggers in California: what to know
What to note
Where you see chiggers, how long it has been going on, and anything you’ve already tried are the most useful details to mention.
A useful next step
Ask about an inspection, what treatment would involve, and whether follow-up visits are included. You don’t need to identify the problem yourself before getting in touch.

Chiggers in California: what the public record shows
Before you compare quotes, it helps to know which chiggers actually live in California, when they are busiest, and what the state figures look like. Everything below links to the agency or university page it came from.

Wildlife association
If a bat roost is removed from a structure, chiggers are one of the parasites that can be left behind.
UC Statewide IPM ProgramWhen chiggers are busiest in California
UC ANR's biting-and-stinging-pest guidance advises avoiding peak biting activity times, usually early morning and evening hours, rather than giving a chigger-specific season.
UC ANR advises staying out of favorable biting-pest habitat such as moist shaded portions of wooded, brush-covered, or grassy areas, wearing long sleeves and long pants tucked into boots or socks, and using DEET on skin and permethrin on clothing only.
