Pest Control Guide: Protecting Your Home from Cockroaches and Fruit Flies

Summer in South Korea is characterized by high temperature and humidity, creating a perfect environment for pests to thrive. For international students or foreign professionals living in a Studio (원룸, won-rum) or older villas, the sudden appearance of pests can be a major source of stress. However, there is no need to worry. You can keep your space comfortable with the right tools and habits. Explore this practical pest control guide provided by Enkostay.

Cockroaches (바퀴벌레, bakwibeolle): Prevention and Eradication Strategies

The first step to eliminating cockroaches is blocking their entry points. They often enter through the Drain (배수구, baesugu) or gaps in windows. Attaching mesh covers or specialized insect-proof stickers to these areas is highly effective. Additionally, it is common for eggs to enter through a Delivery Box (택배 박스, taekbae bakseu) in Korea. It is important to develop a habit of recycling these boxes immediately rather than keeping them inside your home.

Bait (독먹이, dongmeogi) can be found easily at Daiso (다이소, da-i-so) or local supermarkets. Gel-type products from brands like Combat or Zaps are affordable and popular among locals due to their high effectiveness. If you see a pest, use an Insecticide (살충제, salchungje). For fundamental eradication of hidden pests, apply small amounts of gel to pieces of paper and place them in the corners of your furniture.

Fruit Flies (초파리, chopari): Removing the Root Cause and Prevention

Fruit flies swarm around Food Waste (음식물 쓰레기, eumsikmul sseuregi) during the summer because of their strong reproductive capabilities. The best way to prevent them is to handle fruit peels and food scraps immediately. A useful tip for those who cannot empty the trash daily is to freeze food waste in a small, dedicated section of the freezer, which is a common life hack among residents in Korea.

If you already have fruit flies, try a Fruit Fly Trap (초파리 트랩, chopari teu-raep) from Daiso. These inexpensive traps containing an attractant are quite effective at capturing them. Furthermore, pouring boiling water down the sink drain once a week helps prevent fruit fly eggs from hatching.

When You Need Professional Help: Cesco

If pests persist despite trying these methods, seeking professional help from a Pest Control Service (방역 업체, bangyeok eopche) is wise. Cesco is the most recognized company in Korea. While costs vary by the size of the home, their services provide a thorough diagnosis and solution. You may also want to discuss with your Landlord (집주인, jipjuin) about potential support for these costs if the issue is building-wide.
