Treatment options and typical costs
Inspection and Nest Identification
$75–$200
A pro starts by confirming the species and the nest location. Paper wasps, hornets and yellowjackets each call for a different approach.

- Every job; species and nest location decide the method
Preventive Spring Treatment and Follow-Up
$150–$400
Follow-up matters after any treatment around a property. Checking again two weeks later catches anything the first visit missed.
