Red welts after a night's sleep, a rusty smear on the pillowcase, a flat brown bug on the headboard: by the time Angwin residents spot these, the problem has usually been building for weeks. Waiting gives bed bugs time to spread into nearby rooms. Call or send the form and our licensed crew, who drive up to Howell Mountain, will follow up with a free bed bug control quote.
We take requests from every address in ZIP 94508. That includes the Pacific Union College campus, the small village center beside it, the Howell Mountain area that the Census counts as part of Angwin, and the wooded and vineyard parcels spread across the plateau.

A fogger coats open surfaces while the bugs stay tucked inside box springs and bed frame joints. Many bed bugs in California also tolerate the common ingredients in those cans, so the few that get hit often survive.

Bed bugs ride in on luggage, used furniture and clothing.
Angwin sits at about 1,750 feet on a plateau of Howell Mountain, roughly 5 miles north and east of St. Helena and well above the floor of the Napa Valley. The town takes its name from Edwin Angwin, a Cornishman who bought 200 acres here in 1875 and ran a mountain resort. In 1909 Healdsburg College bought that resort for $60,000 and reopened as Pacific Union College, and the town has grown around the campus ever since.
ZIP 94508 holds about 3,200 people and about 1,180 homes. Close to 4 in 10 occupied homes are rented, and in the Angwin CDP itself the 2020 Census put the renter share near half. Most houses date from the 1940s through the 1960s. Students arrive each fall and residents travel down the hill often, so bugs have many ways in.
Pacific Union College Residence Halls
Pacific Union College is a Seventh-day Adventist liberal arts school whose campus covers about 200 acres of a roughly 1,800-acre property. Census figures show about 565 people in ZIP 94508 living in college student housing. Newton Hall houses men, while Andre Hall and Winning Hall house women, and every room is set up for 2 students.
- Students bring their own pillows, blankets, sheets and mattress covers, so everything that arrives at move-in should be washed and dried hot first.
- The college asks students not to bring furniture, but used pieces for off-campus rentals deserve a close look.
- Anyone with bites should report them to housing staff in writing and leave the mattress in the room for the inspector to examine.
Fire Evacuations and Overnight Stays Away From Home
Angwin was evacuated in August 2020 during the Hennessey Fire, part of the LNU Lightning Complex. About a month later, on September 27, the Glass Fire brought evacuation orders for Pacific Union College and nearby Howell Mountain communities. Many families slept in hotels, shelters or with relatives.
Napa County does not allow vacation rentals of less than 30 days in its unincorporated areas, which include Angwin. Visitors to the college and the Howell Mountain wineries therefore tend to stay in permitted lodging down in the valley, then drive up the hill with their bags.
- After any stay in a hotel, shelter or guest room, open suitcases in the garage or on a hard floor, not on the bed.
- Put clothing through a dryer on high heat for at least 30 minutes before it goes back in a drawer.

Renter Rights in Angwin
California Civil Code 1954.600 to 1954.605, known as AB 551, covers bed bugs in rented homes everywhere in the state. Houses, cottages and apartments rented to students, faculty and staff in Angwin follow the same rules.
- Landlords must give tenants a written bed bug notice.
- A landlord cannot show, rent or lease a unit they know has bed bugs.
- After a licensed pest control operator inspects, the landlord must share the findings with affected tenants within 2 business days.
- Tenants who report bed bugs are protected from retaliation.
Nearly half of the occupied homes in the Angwin CDP are rented. Tell the landlord about bed bugs in writing, write down the date and save a copy for yourself.
What Bed Bug Treatment Costs
Cost turns on the size of the home, how many rooms are involved and the method chosen. Angi's 2026 national averages list a visual inspection at $65 to $200, a K9 search at $300 to $600 and treatment at $200 to $400 per room, with whole homes usually between $1,500 and $6,200. Travel up from the valley may be added, so trust the written estimate.
Angwin Bed Bug Questions
Does Angwin have its own city government?
No. Angwin is an unincorporated community and census-designated place on Howell Mountain, so Napa County handles local government. The 2020 Census counted about 2,630 people in the CDP, and ZIP 94508 holds roughly 3,200 once the outlying hillside parcels are included.
I live in a Pacific Union College residence hall and have bites. What should I do first?
Tell your resident dean or the campus housing office in writing the same day and keep a copy. Leave the bed where it is, bag your sheets and clothes, and do not sleep in a friend's room down the hall, because that can move bugs into a second room.
Where does your team usually come from to serve Angwin?
Our technicians usually drive up from the valley floor around St. Helena or Napa, or over from the Santa Rosa area. Ask whether the climb up the mountain adds a trip charge.
What does bed bug treatment cost for a home in Angwin?
As a rough guide, Angi's 2026 US averages put treatment at $200 to $400 for each room, with whole homes often landing between $1,500 and $6,200. A hillside lot or a long gravel drive may change the figure, so go by the written quote.
We were evacuated in 2020 and stayed in hotels. Should we still worry?
Not years later, if nobody has had bites since. After any hotel or shelter stay, though, unpack bags outside the bedroom, run clothes through a hot dryer and look over mattress seams for a few weeks.
