What should I do about "Kobae" that I care about? Introducing countermeasure goods! [August 2021 version]-Fav-Log by ITmedia
It's almost the end of August, but the hot days continue. Speaking of hot days, you may be worried about "small flies" that appear in the kitchen sink, around the garbage, and in the bathroom (bathroom). There must be a lot of people who are annoyed when they enter the field of vision.
First of all, what kind of creature is a small fly? Let's think about how to prevent it from entering or not to see it.生ゴミや水回りによく出てくる「コバエ」はどこから……？
In the first place, what kind of creature is "Kobae"?
Kobae, as the name suggests, is a general term for flies with a body length of about 2 mm. There are so many types of flies, and most of the flies you see in Japan belong to the following four categories.
Fruit flies are a common sight in kitchens and around garbage. Fruit flies, known in English as "fruit flies", are known for their love of fruit. Strictly speaking, they often swarm ripe fruits, vegetables, and seasonings, so be careful of these garbage, leftovers, and splashes.
Flea flies tend to hang around kitchen waste and animal droppings. Moth flies are nocturnal and are often found in bathrooms and sewers. Fungus flies are more likely to appear in the shade of trees or around potted plants.「fruit fly」と呼ばれるショウジョウバエは、熟した果物や野菜が好物で、生ゴミやそれらの残りカスによく集まってきます
Where do flies come from?
As mentioned earlier, the fruit fly is only a few millimeters long. Therefore, even if you do not leave the front door or window open, they can enter through even the slightest gaps in doors, windows, ventilation fans, etc.
I thought, "How about using an insect net?" Introducing a screen door does not mean that you are safe.
What can I do to prevent flies from invading?
What can I do to prevent the infestation of flies? Here are some easy-to-implement measures.
Fruit flies basically come to environments that lack cleanliness. Therefore, keeping the sink and bathroom clean is one of the important measures.
When cleaning the sink, don't forget to clean the dust tray, drain, and triangular corners. In particular, collect dust trays and triangular corners frequently. If you prepare a disposable "draining garbage bag", garbage collection will be easy.ダストトレーや三角コーナーの清掃は、汚れがひどくなければ中性洗剤でも大丈夫です。汚れがひどい場合は、塩素系漂白剤やアルカリ性の洗剤を使って掃除することをおすすめします（スポンジなどでこする際は、必ず手袋を装着してください）流し台のダストトレーは、発泡タイプのクリーナーを使った掃除もおすすめです。ゴミをしっかり取り除いてから使いましょう最近は三角コーナーなしで“自立”できる水切りゴミ袋もあります。これを使えば、小まめに生ゴミを捨てるのも楽です（画像はネクスタ「シンク用水切りゴミ袋 スタンドタイプE、出典：Amazon）コバエの種類によっては、排水口のぬめりを求めてやってくることもあります。排水口のパイプ清掃も有効なコバエ対策といえます
Fruit flies often gather in food waste. Let's take out raw garbage for collection diligently. In the summer, flies tend to appear within 2-3 days. Even better, use a trash can with a lid that seals. If you can't seal it, tie the garbage bag tightly and seal it.
In addition, leftovers in drink cans and bottles are often overlooked as a cause of flies. When you throw it away, please rinse it well with water. Similarly, unwashed dishes are more likely to attract flies, so wash your dishes as soon as possible.コバエは生ゴミの臭いに誘われてやってきます。密閉できるゴミ箱に捨てるようにしたいです（画像はアスベル「キッチン生ゴミペール EBAN 11L」のベージュ、出典：Amazon）
Again, because the body of the fruit fly is so small, it can fit through even the tiniest of cracks. Therefore, by minimizing the gaps between the entrance and windows, you can prevent the intrusion of the fly itself to some extent.
For example, "gap tape" that fills gaps between doors and windows was originally used to "improve cooling/heating efficiency," "prevent drafts," and "suppress the sound of opening and closing doors and windows." It can also be used for holding down.
If you're already using bug netting, replacing it with a finer mesh will make it more difficult for flies to get in. It is also effective to use an insect screen that contains an insect repellent.
However, measures against gaps may not be able to prevent the invasion of flies. We recommend that you give priority to the "cleaning" measures mentioned earlier, and then implement additional measures.ドアや窓のすき間を埋める「すき間テープ」は、コバエ侵入対策にも使えます（画像はニトムズ「すきまテープ徳用ロング 2巻パック」、出典：Amazon）網戸用の虫よけ網は「メッシュ」の数字が大きいほど目が細かくなります。一般的な網で使われる「18メッシュ（18＃）」（幅1.15mm）でも多くのコバエは防げます。コバエ以外の虫にも効果のある虫よけ成分を含んだ虫よけ網もあります。なお、網戸用の虫よけ網は、取り換えるために必要な資材や工具は原則として別売です。最近は、窓に直接貼り付ける「簡易網戸キット」もよく見かけます（画像はダイオ化成「虫のイヤがる網 20メッシュ 90cm×2m」、出典：Amazon）
What should I do with infested flies?
The flies that have entered are unexpectedly noticeable. You will also be addicted to food and drink. If by any chance you enter the house, I do not want you to approach as much as possible. However, because of their small size, flies can be difficult to get rid of.
Therefore, I will introduce some methods of capturing and exterminating flies in case they get inside.
The quickest way to catch and exterminate small flies is to use special trapping agents.
Recently, there has been an increase in the number of "trapping agents that do not use insecticides" that release the odor that the flies like and capture the flies that are lured by that odor with an adhesive material. However, trapping agents that do not use insecticidal ingredients may not be very effective against moth flies and mushroom flies due to their characteristics. If you need to take measures against these flies, we recommend using traps or insecticides containing insecticidal ingredients.最近のコバエ捕獲剤は、殺虫成分を一切使わないタイプが増えています（画像は大日本除虫菊「KINCHO コバエがポットン 吊るタイプ」、出典：Amazon）
We recommend using an insecticide to get rid of flies that have already clung to food waste. Insecticides are more effective for moth flies and mushroom flies that traps may not catch.
Recently, there is also a compact insecticide that specializes in small flies. Some of them keep flies away for a while after one spray.最近はコバエに特化した殺虫剤も販売されています（画像はアース製薬「コバエアーススプレー」、出典：Amazon）
