Top 10 Foggers and Disinfectants for Boutique Hotels With Indoor Pools: Lessons from Washington Finds 14 Cryptosporidium Cases After Swimming at McMenamins Anderson School Hotel Pool, 2026
Fox19 reported 14 people ill after swimming in the McMenamins Anderson School hotel pool in Bothell, Washington, with Cryptosporidium confirmed; officials advised avoiding pools for two weeks after diarrhoea and showering with soap before swimming. What should Thai hotels prepare?
The Real Story from the News: A Parasite That Tolerates Pool Chlorine
Fox19 reported on 1 October 2026 that 14 people fell ill after swimming in the hotel pool in late August; Cryptosporidium was confirmed and no one was hospitalised.
A September inspection found no violations, and officials advised avoiding public pools for at least two weeks after diarrhoea or vomiting and showering with soap before swimming.
Why Choosing the Right Equipment Matters
Thai hotels and resorts have pools that children use often. Cryptosporidium survives normal chlorine levels for a long time. Pool water management needs specialists; foggers do not treat pool water or water systems. Signs telling people with diarrhoea not to swim, pre-swim showers and cleaning changing rooms and nappy stations reduce risk.

Prefer Not to Do It Yourself? Use a Professional Service
If buying equipment is not practical or the area is too large, use the World Health Disinfection disinfection service or ozone treatment service. The team wears full protective equipment, chooses products to suit the germ and surface, and reports after the job.
Frequently Asked Questions
Q: Can foggers treat pool water? A: No. Pool water needs water-system specialists; foggers are for surfaces and rooms only.
Q: How long before the area can be used? A: After ULV fogging, areas are typically usable about 30 minutes later. For ozone treatment, no people or pets may be inside and the room must be ventilated before use.
Q: Can I get a tax invoice? A: Yes. Tax invoices are issued and 3% withholding tax is supported. Call 065-556-6294 or LINE @whd268.
Health References
Follow disease updates from Thailand's Department of Disease Control (hotline 1422) and the World Health Organization. Disinfection reduces germs in the environment and is not medical treatment; anyone with symptoms should see a doctor.
Summary
Bothell shows even inspected pools carry risk. Hotels that inform guests and maintain showers cut illness.
