One unfortunate truth about Japan is that, like any other country, it has bugs that can sometimes get in your home or apartment. Even if you live on the 15th floor of an apartment building, you may still encounter the occasional unwelcome housemate. So, we understand how you feel when you meet a creepy crawler face to face. Below, we describe a couple of the most common types of bugs that you might meet in your house and suggested ways for dealing with them.

Mosquito - Ka

Mosquito (Ka in Japanese) season in Japan is during summer and autumn. The mosquitoes are persistent and difficult to get rid of if you are going to rely on the ‘swatting’ method. Fortunately, malaria, which is a mosquito-borne disease - is rare in Japan. However, the need to protect yourself from mosquito bites is still important if you want to enjoy a good night‘s sleep or being disrupted from your daily activities because of an annoying and hungry mosquito. There are several excellent mosquito products on the market that you can use to repel and kill mosquitoes. You can easily find them online, at a supermarket /drugstore.

Mosquito Repellent to Use Outside or at Home

Osoto de No-Matto(おそとでノーマット)

You can carry this Osoto de no matto around like the photo below. It does not need to be plugged in because it comes with its own battery and also has its own motor and fan to allow for extensive coverage. This will last for 200 hours or over 33 days if you turn it on only 6 hours a day.

Herb Mushiyoke(ハーブ虫除け)

Fortunately, you are not alone and there are ways to deal with any sort of pest. There are products similar to what was described above available to deal with almost any kind of pest you may encounter.
