The first redbacks found in Japan are believed to have come from Australia, with the earliest reported sightings in Osaka in the mid-1990s. Seakagokegumo, or セアカゴケグモ (redback spider), weren’t an issue in Japan until about 20 years ago. This may release eggs it carries and actually leads to a much bigger problem a day or two down the line. Do not step on or squash a cockroach if you see it.The traps are going to be working for you while you’re not in the house, but when you spot a roach, the spray is one of the best ways to keep them under control. There are also a variety of sticky and poisonous traps you can lay down to catch them.To rid yourself of a possible infestation, you’ll need to buy a spray especially targeted at roaches.The same might be true for cleanliness in the countryside or an older house, but here, one generally means more. If you’re in a big city or newer house, spotting one of them indoors is not necessarily indicative of a nest or an infestation, nor does it call your cleanliness into question. The hot, humid summer climate in Japan is the perfect breeding ground for these, the most versatile insects. They are much bigger and more tenacious than their European and American counterparts.

Gokiburi, or ゴキブリ( cockroaches) in Japanese, are by far the most common household creepy crawlers you will encounter in Japan-especially during summer. Go to the hospital as soon as you can, just to be on the safe side.Squeeze the stinger and venom out as quickly as you can if you’re stung.Carry antihistamine cream with you if you’re going out where they may be.Wear bright colors, as these bugs are attracted to black clothes.You are most likely to encounter one of these while hiking, but some simple steps can help limit your exposure to them. Suzumebachi are rare in urban areas, so you are unlikely to have them show up in your house unless you live in the countryside near mountains or forests. Therefore, you might be more likely to be stung in more rural areas, making it far tougher to seek medical attention if someone does go into anaphylactic shock. The danger posed by suzumebachi comes from the fact that they often live in swarms. However, a single attack is unlikely to be fatal to an adult unless you have a wasp/bee sting allergy or you are stung several times in quick succession. The suzumebachi is larger and has a far more venomous sting than conventional hornets. Japan’s infamous suzumebachi, or “killer hornet,” is one of the more dangerous creatures on this list, as it does kill a dozen or so people every year.
