If you find a wasp or hornet nest under your eaves, in a garden tree or in a corner of your balcony, you need to know who to call. This page covers Matsuyama City, Imabari City and Niihama City in Ehime. It explains what the city offices do and do not do, what to do if you rent, what a private company costs, and what to do if someone is stung.

In short

If you rent, contact your property manager or landlord before you call a company (section 3).
Niihama City says it does not subsidize removal costs. The Matsuyama and Imabari pages do not mention any subsidy and say removal is paid (section 2).
Hachi 110ban lists removal from ¥12,100 (bees and paper wasps) or ¥16,500 (hornets), tax and travel fee included. These are starting prices, and its page and form are in Japanese only (section 4).

1. Should I remove the nest myself?

Imabari City / Matsuyama City / Niihama City

Imabari City says removing a nest is dangerous, and that you should ask a professional company, especially for hornets. Matsuyama City also says removal is risky and recommends a professional company.

Niihama City explains why. A queen starts a nest alone in spring, and wasps are most active in summer and autumn while they raise young. The hornets and paper wasps often seen in the city are aggressive, threaten people who come near the nest, and finally sting. Nests are often built in garden trees, thick branches, under eaves and in the ground. The city asks people to check for nests before they trim trees or enter long grass.

Niihama City’s page lists these precautions:

Do not go near a nest you find.
If you often see wasps in one place, a nest is probably nearby even if you cannot see it.
Wasps react to black, so wear white or light clothes outside.
Avoid strong perfume and hair products.
Do not eat ripe fruit or drink juice where wasps are flying.

Imabari City adds that wasps can get mixed into laundry or bedding, so check when you bring it in.

Niihama City says wasps stay active until around October. If you find a nest or wasps, do not swat at them. Keep low, and move away quietly and as far as you can.

2. What does my city office do?

Matsuyama City / Imabari City / Niihama City

None of the three cities removes nests on private land. Each asks the owner or manager of the place to deal with it. The cities differ in how they help you find a company.

City	Removes nests?	Where to ask	Finding a company
Matsuyama City	No (paid, by a company)	089-911-1862	Ehime Pest Control Association
Imabari City	No	0898-36-1535	The association, or Silver Human Resources Center
Niihama City	No, and no subsidy	0897-65-1512	List of 4 city companies

2.1 Matsuyama City

Matsuyama City

The Living Hygiene Division (生活衛生課) handles questions at 089-911-1862. The city lists the Ehime Pest Control Association as a group that introduces companies, and says removal is paid. The association is at 3-1-54 Kuwabara, Matsuyama City, phone 089-913-1064. Google Maps

2.2 Imabari City

Imabari City

The Environmental Policy Division (環境政策課) handles questions at 0898-36-1535. For a company, the city also points to the Ehime Pest Control Association (089-913-1064). It adds that the Silver Human Resources Center (シルバー人材センター, 0898-22-2003) may be able to help in some cases.

2.3 Niihama City

Niihama City

The Environmental Policy Division (環境政策課) handles questions at 0897-65-1512. The city says it neither removes nests nor subsidizes removal costs. Its page lists the names and phone numbers of four removal companies in the city, taken from the phone book. The city says prices vary a lot with the type of wasp, the size and height of the nest, and the place, so describe the situation in detail and confirm the price before you ask for the work.

2.4 Is there a subsidy?

Matsuyama City / Imabari City / Niihama City

None of the three city pages we used lists a subsidy for removal. Niihama City says clearly that it does not subsidize it. Matsuyama City and Imabari City say removal is paid and tell you to use a professional company. Plan on paying the full cost yourself, or the building owner paying it.

3. What if I rent, or the nest is in a park?

Official advice (Japan)

If you rent, call the company that manages the building, or your landlord, before you look for a removal company. The three cities treat the owner or manager as the one who deals with the nest. The National Consumer Affairs Center of Japan also lists asking the manager or landlord first as an option for rental homes.

Nests in public places are handled by whoever manages them. Niihama City says nests in places the city may manage, such as parks and street trees, can be dealt with by the city department in charge. If you are not sure, ask the Environmental Policy Division or the department you think is in charge. The city gives city housing (Building and Housing Division, 建築住宅課) and parks (Urban Planning Division, 都市計画課, 0897-65-1270) as examples.

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, by phone or form, to member companies, and a member company does the survey and removal. Its page, request form and 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.

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 the lowest prices. Hachi 110ban says some areas and member companies cannot offer the listed price, and that extra fees apply if the nest is hard to find, hard to take out or high up. The price you pay is set by the quote at your home. How far into Ehime a company will go depends on the member company, so give your address when you ask.

Send your request. Use the form or call. Hachi 110ban says it takes requests 24 hours a day, every day.
A member company comes to check. It looks at the type of wasp and the nest. Hachi 110ban says the survey and quote are free, with no travel fee at this stage. It also notes that a fee may apply depending on the area, company or site, and that it will tell you beforehand.
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.
Removal. The company removes the nest.
Pay after the work. Some member companies ask for payment before the work. Payment is by cash or credit card, and fees may apply or cards may not work in some areas.

The terms of use say Hachi 110ban itself is free to use. Your contract is directly with the member company, so you cancel or end it by contacting that company. Hachi 110ban is one of several ways to find a company; the city pages in section 2 give others.

5. How do I avoid a high bill?

Official advice (Japan)

Important

Before the work, ask for the total price, the name of the company that will actually do the work, whether you pay if you cancel, and whether the price can go up later.

The National Consumer Affairs Center of Japan warned in April 2024 that consultations about pest and animal control had grown to about 1.5 times the level of the same period a year earlier. One case it lists is a person who was told they might die from a sting and asked for removal, then wanted to cancel because the bill was high.

In March 2025 the center explained that an advertised “from ¥X” or “base price” does not mean the work will cost that much. It says to compare quotes from several companies, and not to pay on the spot for a bill you do not agree with. If the final bill is very different from what you were told, the cooling-off rule for door-to-door sales may apply. If you are in trouble, call the consumer hotline 188, which connects you to a local consumer center.

6. What if someone is stung?

Niihama City / Ehime Prefecture

If the person feels unwell after a sting, or shows signs such as confusion or drowsiness, pale lips or rough breathing, call 119. Niihama City lists these first steps:

Wash the stung area well with running water. Wasp venom dissolves easily in water.
Pinch the area to squeeze out the venom. Do not suck it out with your mouth.
Apply an over-the-counter insect-bite medicine and cool the area with an ice pack or similar.

If the stinger is left in the skin, remove it gently with tweezers. Do not pinch it with your fingers.

Niihama City says symptoms start in about 15 minutes. A second sting is more likely to cause a serious reaction, and anaphylactic shock can be life-threatening, so see a doctor early. Signs of shock listed on the city’s park page are confusion or drowsiness, a weak pulse, strong stomach pain or vomiting, pale lips or nails, rough breathing, a hoarse voice and coughing.

6.1 Not sure whether to call an ambulance?

Ehime Prefecture

Call the Ehime emergency telephone advice line #7119 (えひめ救急電話相談). Nurses and doctors answer 24 hours a day, every day. They judge how urgent the case is and tell you which medical facility is nearby. From mobile phones other than NTT docomo and Rakuten, from dial phones and from IP phones, call the toll-free number 0120-79-7119. If that does not work either (some IP phones), call 089-909-9935. The pages we used do not say which languages the staff speak, so it may be Japanese only.

The line is run by Ehime Prefecture together with 20 cities and towns, so the same number works from Matsuyama, Imabari and Niihama. If a child is stung at night and you are worried, see Child sick at night or on a holiday in Ehime: #8000, #7119 and children’s emergency clinics in Matsuyama, Niihama and Imabari.

Common questions

If I call the city office, will it come and remove the nest?

No. Matsuyama City, Imabari City and Niihama City do not remove nests on private homes or land. The offices give you information about groups and companies you can ask.

Is there a subsidy for removal costs?

Niihama City says it does not subsidize removal costs. The Matsuyama City and Imabari City pages do not mention a subsidy, and say removal is paid.

There is a nest in a park. Who do I contact?

In Niihama City, the city tells you to contact the Urban Planning Division (0897-65-1270) about nests in parks. For parks in Matsuyama City and Imabari City, ask the department that manages the park.

If you ask a company, tell it the type of wasp and where and how high the nest is, get a quote, and agree only when you accept the total price.

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).
If you want it removed, get a quote and check the total price before you agree (section 5).
Keep away from the nest until it is dealt with. Wasps stay active until around October (section 1).
