Contract terms
Terms as recorded from the linked sources.
Cascade Pest Control 11 terms
Main plan ‘Cascade Complete Care’ is ongoing service at monthly, bi-monthly or quarterly visits; ‘Cascade Green Complete Care’ is a monthly organic service. Both include an initial treatment plus ongoing maintenance.11
Company guarantee (‘Complete Service Warranty’): re-service at no charge if targeted pests significantly breach defenses between scheduled services (company claim).11
Monthly service is required for rodent protection in post-and-pier homes, including mobile homes.11
Consumers’ Checkbook (Puget Sound) price comparison puts Cascade’s prices well above the area average.12
One Google reviewer mentions a 90-day warranty included in a one-time package (customer report, not published company terms). Separately, a 2-star Google reviewer on the Seattle listing said the company would not return for an ant problem without a monthly contract (see the Seattle review excerpts).9
Review by ‘Nicolas D.’ (Google, Snohomish listing per research-time capture). During verification Google Maps served a limited view that did not show this review, so the source is the Google-review widget on the company homepage, where the same review text appears.
Company’s published service-agreement Terms and Conditions (My Service page, ‘Last Updated 6/23/23’): recurring (maintenance) service continues until either party cancels with 30 days’ written notice by USPS or email; the client pays in full for any service not rescheduled with 24 hours’ notice. No minimum term and no early-cancellation fee appear in the published payment and cancellation terms.13
The terms sit in collapsed <details> panels; the cached copy was read with the panels opened. The page index still says ‘[Currently being updated May/June 2023]’. Signed customer agreements were not seen. The same section also says to ‘See specific Cascade agreement’s definitions and limitations of warranty’ and that service-specific terms (e.g. original pricing, target pests) are set per agreement. Verifier re-check October 13, 2026: all quoted terms confirmed verbatim in the raw HTML of a fresh capture.
Published terms: on rodent bait-station accounts, a $75 bait-station retrieval fee applies on cancellation unless the stations can be collected at the final service.13
Published terms: accounts unpaid after 30 days get a $30 late charge (plus a $30 NSF fee for returned checks and reasonable collection costs); a past-due account is put on hold, which also blocks warranty visits.13
Published re-treatment warranty conditions: service maintained without interruption over the previous 4 months, the company’s recommendations followed (e.g. exclusion work for rodent accounts), and the account current. Quarterly plans are ‘normally without warranty’; skipping a service suspends the warranty.13
The My Service page’s cancellation section tells customers to call the office to cancel and offers suspending service for up to 6 months instead. The formal terms on the same page require 30 days’ written notice (USPS or email), so the two instructions differ.13
Company blog post on Boise/Treasure Valley pest-control costs (pricing ‘as per September 2026’). The ranges are the company’s survey of local Boise-area companies, and the post says Cascade’s prices fall within them (company statement): initial setup for ants and spiders $150-$320; initial rodent setup $150-$425 for most homes; ongoing bi-monthly or quarterly service $120-$150 per visit (for a home up to 3,000 sq ft); one-time home pest service $150-$430.14
Aspen Pest Control 9 terms
Terms of Service (updated 2023): cancelling before the end of the initially scheduled services triggers a $250 contract termination fee; later cancellation must be in writing and prior to 30 days of the next scheduled service.8
Binding arbitration clause (American Arbitration Association rules, in Vancouver, Washington) in the Terms of Service.8
Liability limited to the amount paid; agreement does not cover termites, bed bugs, wildlife, fleas or ticks unless noted.8
Late payments: 1.5% monthly finance charge on invoices over 30 days past due; $10 extra for Saturday regular services.8
Home Protection Plan is a quarterly (every 90 days) exterior treatment with interior included on request.9
Guarantee: unlimited free re-service between regular treatments; one-off treatments typically carry a minimum 30-day guarantee.10
Late-arrival promise: next regular service free if technician is late without calling ahead.11
Reviewer-reported prices on Angi range roughly $90–$230 per job (e.g. $90, $119, $200, $230).12
A 2018 HomeAdvisor reviewer reports a better rate with a contract but says customers are not locked in.13
