1. Why should I not remove a nest myself?

Ube City / Yamaguchi City

Ube City says the danger of being stung by a hornet (スズメバチ, suzumebachi) is greatest from August to November, when the colony is raising new queens. The city calls removing hornets “very dangerous” and asks you to use a professional company. It adds that if the nest is somewhere that does not affect daily life and nobody is at risk of being stung, you do not have to remove it. Hornets (Ube City, Japanese)

Ube City’s FAQ mentions removing a nest yourself with a store-bought insecticide, but answers that for dangerous wasps such as hornets you should ask a company. FAQ: A wasp nest is dangerous. What should I do? (Ube City, Japanese)

Two cities also say how to behave near a nest. Ube City says hornets react to sideways movement, so do not wave them away or run. Lower your body and back away slowly. Black clothes and black hair attract them, and perfume or hair products can provoke them. A dead hornet can still sting by reflex for a while, so do not touch it.

Yamaguchi City says to avoid sudden movements, such as hurrying past a nest or shaking the ground, and to wear light-colored clothes. If guard wasps threaten you, for example in the mountains, do not shout or swat them. Cover your head, keep low and move away slowly. Beware of wasp nests (Yamaguchi City, Japanese)

2. What does my city office do?

Shimonoseki / Yamaguchi City / Ube / Shunan

Shimonoseki, Yamaguchi City, Ube and Shunan do not remove wasp nests. In all four cities, the owner or manager of the land or building asks a company to do it. The offices below handle questions. The pages we checked do not say whether staff speak English.

2.1 Shimonoseki

Shimonoseki City says hornet and paper wasp nests grow from about July to October. Because removal is very dangerous, it advises you to consult a professional company. It tells you to look for one on the internet or in the classified telephone directory. The page is run by the Living Hygiene Division (生活衛生係, 083-231-1540). About removing wasps (Shimonoseki City, Japanese)

2.2 Yamaguchi City

Yamaguchi City says to look under “ハチ駆除” (wasp removal) or “消毒業” (disinfection) in the classified telephone directory, and states that the cost of removal is paid by the person who asks for it. Questions go to the Environmental Hygiene Division (環境衛生課): 083-934-2690, or the Southern Hygiene staff, 083-973-8136.

2.3 Ube

Ube City publishes a list of 11 removal companies in the city, with their names, locations and phone numbers. The city notes that prices differ by company, so you can call a few from the list and compare. Questions about pests go to the Environmental Policy Division (環境政策課, 0836-34-8251).

2.4 Shunan

Shunan City also asks the owner or manager to consult a professional company, and says to find one on the internet or in the classified telephone directory. The contact is the Living Hygiene staff of the Environmental Policy Division (0834-22-8322). About removing wasps (Shunan City, Japanese)

3. What if I rent?

Official advice (Japan)

If a nest appears on your balcony or in a shared area, tell your property manager or landlord before you call a company. The four cities say removal is up to the “owner or manager” of the land or building, which for a rental means the party that manages the building. The National Consumer Affairs Center of Japan also says that, for a rental home, it can help to ask the manager or landlord before you contact a company.

4. How much does Hachi 110ban cost, and can I use it in English?

Depends on the provider

Hachi 110ban is a contact service run by Sharing Technology Inc.. It passes your request to member companies, which do the survey and removal. Its page, the request form and the terms of use are written in Japanese, and the page does not say whether staff speak English. If you cannot read Japanese, ask a Japanese-speaking friend or coworker to help you, or use a translation app on the form.

Wasp type	Removal price	Note
Honeybee (ミツバチ)	From ¥12,100	Tax and travel fee included
Paper wasp (アシナガバチ)	From ¥12,100	Tax and travel fee included
Hornet (スズメバチ)	From ¥16,500	Tax and travel fee included

These are starting prices. Hachi 110ban says that some areas and member companies cannot offer the listed price, and that extra fees may apply if the nest is hard to find, hard to reach or high up. The final price is set by the quote at your home. Whether your address in Yamaguchi is covered depends on the member company, so give your address when you ask. Payment is by credit card or cash, and fees or card limits may apply in some areas.

Send your request. Use the form or call. Hachi 110ban says it takes requests 24 hours a day.

Get a quote. Hachi 110ban says it does not add charges to the quoted price and that you can cancel at this point without a fee.

4.1 What should I check before signing?

Important

Before the work, check the total price, the name of the company that will come, the cancellation fee and any extra charges. The National Consumer Affairs Center of Japan says complaints about pest and animal control are rising. One example it gives is a person who was told they could die from a sting, felt afraid, ordered removal, and then wanted to cancel because the bill was high. Beware of pest and animal control trouble (Japanese)

The center says the price depends on the size and structure of the home and on the situation, so an advertised “from ¥X” price does not mean the work will cost that much. Do not sign with a company that stirs up your fear to make you decide on the spot. Do not pay a bill you do not agree with. Get quotes from more than one company. If the bill is far from the price you were told, the cooling-off rule for door-to-door sales may apply. You can call the consumer hotline 188 to be connected to a local consumer center.

5. What else should I know in Yamaguchi?

Yamaguchi Prefecture / Yamaguchi City / Shunan City

The emergency medical advice line #7119 works in most Yamaguchi cities, but Iwakuni and Hagi connect to different services. Save the number for your city before you need it.

#7119 (Yamaguchi Emergency Safety Center): works in Shimonoseki, Ube, Yamaguchi City, Hofu, Shunan and other cities. Nurses give advice by phone on whether to go to hospital, 24 hours a day (or call 083-921-7119). In Iwakuni and Waki Town, #7119 connects to the Hiroshima area service; from a mobile phone, call 082-246-2000. Hagi and Abu Town use “Hagi-Abu Health Dial 24” (萩・阿武健康ダイヤル24). The prefecture does not say which languages the advisors speak, so it may be Japanese only. #7119 emergency medical advice (Yamaguchi Prefecture, Japanese)
An invasive hornet: a nest of the Tsumaaka hornet (ツマアカスズメバチ, a designated invasive species) was found and removed in Hofu on November 18, 2019. Yamaguchi City says this was the first confirmation on Honshu. It is dark all over with an orange tip on the abdomen, and often builds a larger nest than native species high in a tree. If you find a suspicious nest, report the date, place and situation (a photo if possible) to the city’s Environmental Policy Division (Yamaguchi City’s wording) or to the Chugoku-Shikoku Regional Environment Office (086-223-1561). Beware of the invasive Tsumaaka hornet (Yamaguchi City, Japanese)
Shunan City says that, as of December 26, 2024, the hornet had not been found in the city, but it warns that its range may spread. About the Tsumaaka hornet (Shunan City, Japanese)
Prevention for next year: Yamaguchi City describes a plastic-bottle trap. Hang it on garden trees from March to May, when queens that survived the winter start building nests. Take it down from June, when worker wasps become active, because it can attract them instead. Plastic-bottle traps (Yamaguchi City, Japanese)

6. What if someone is stung?

Ube City

Ube City says to lower your body and leave the spot at once. A hornet can sting many times, and a wasp that has stung releases a scent that calls others, so staying can bring many wasps. Once you are safe:

Wash the wound well with running water. Tap water is fine. Squeeze out the venom by hand.
Cool the area with water or ice.
See a doctor early. Get treatment at a hospital.

If it is night or a holiday and you cannot decide whether to go, call #7119 (for people about 15 and older). For children under 15, Yamaguchi Prefecture’s pediatric emergency advice line is #8000. For where to take a child at night, see Child Sick at Night in Yamaguchi. If the person has trouble breathing or seems seriously unwell, call 119.

Common questions

Does the city pay for removal?

None of the four cities removes nests, and Yamaguchi City says the person who asks for removal pays. The pages we checked do not mention a subsidy.

Should I remove an empty nest left over in winter?

Ube City says the wasps leave the nest in winter, and hornets do not reuse an old nest in later years.

Can I use a store-bought insecticide?

Ube City mentions removal with store-bought products, but answers that for dangerous wasps such as hornets you should ask a company. If you cannot tell what kind of wasp it is, stay away and ask a company or your city office.

Next steps

Find out who owns or manages the place where the nest is, and ask your manager or landlord first if you rent (section 3).
Call your city office if you are not sure what to do (section 2).
Get a quote and check the total price before you agree (section 4).
