Cockroaches are one of the most unpleasant pests that can invade a home. They can be difficult to get rid of and can cause health problems. Among the different types of cockroaches, German cockroaches are the most common species found in households. They are small, light brown in color, and have two dark stripes on their backs. In this article, we will discuss what attracts German cockroaches and how to prevent them from infesting your home.

Factors that Attract German Cockroaches


The main reason why German cockroaches come into our homes is food. They feed on anything that is organic, such as crumbs, grease, and garbage. They are particularly attracted to sugary foods and beverages. Therefore, keeping your kitchen clean and free of food debris is essential to prevent a German cockroach infestation.


Like any living creature, German cockroaches also need water to survive. They can live for up to a month without food but can only survive for a week without water. Therefore, they tend to hide in damp areas such as under sinks and leaky pipes. Keeping your home dry and fixing any plumbing issues can help in preventing an infestation.


German cockroaches prefer warm temperatures between 70-80 degrees Fahrenheit. Therefore, they are most commonly found in kitchens, bathrooms, and other warm areas of the home.


German cockroaches seek shelter during the day and come out at night to feed. They prefer dark and tight spaces such as cracks in walls, behind appliances, and under cabinets.

Prevention Tips

Preventing a German cockroach infestation is easier than getting rid of one. Here are some tips to keep them out of your home:

  • Keep your kitchen clean: Wipe down counters after preparing food, sweep floors regularly, and clean up spills immediately.
  • Seal up food: Keep all food in airtight containers or in the refrigerator to prevent cockroaches from accessing it.
  • Fix plumbing leaks: Fix any leaky pipes or faucets to prevent damp areas that cockroaches can hide in.
  • Declutter: Get rid of any clutter that can provide hiding spots for cockroaches.
  • Seal entry points: Seal any cracks or holes in walls, floors, and doors to prevent cockroaches from entering your home.
  • Use baits and traps: Cockroach baits and traps can be effective in preventing an infestation.

Getting Rid of German Cockroaches
