How to Deal with Insects During Japan’s Rainy Season
Tips for Apollo Properties Osaka Residents

Japan’s rainy season (tsuyu), typically from early June to mid-July, brings high humidity, heavy rain—and unfortunately, a spike in insect activity. Whether you’re staying in one of our furnished apartments or a share house, it’s important to take a few simple steps to keep your living space clean, dry, and bug-free.

1. Keep Food Sealed and Surfaces Clean

Ants, cockroaches, and fruit flies are attracted to food scraps and sugary residues. Always wipe down tables and countertops after cooking and eating. Store food in sealed containers, and don’t leave dirty dishes in the sink overnight.

2. Take Out the Trash Regularly

Wet weather accelerates the breakdown of food waste, creating odors that attract bugs. Separate and dispose of garbage properly and follow the collection schedule in your neighborhood. Using garbage bags with strong seals or deodorizing agents helps too.

3. Ventilate and Dehumidify

Moisture attracts insects—especially cockroaches. Use a dehumidifier or air conditioner to control humidity inside your room or apartment. Open windows when possible (with screens!) to allow airflow.

4. Use Natural or Electric Repellents

Citronella candles, mosquito coils, and plug-in repellents are widely available in Japan. You can also buy insect traps and sprays from any local drugstore or 100-yen shop.

5. Seal Entry Points

Check for gaps around windows and doors. If needed, use weather stripping or tape to block small holes where insects might enter.

Staying proactive can make all the difference during the rainy season. At Apollo Properties Osaka, we care about your comfort and want to ensure your home stays clean and enjoyable, no matter the weather!
