How Can I Avoid Bringing Bed Bugs Into My Home

There are a few simple steps you can take to avoid bringing bed bugs into your home:

  • Inspect all used furniture before bringing it into your home. Look for any signs of bed bugs, including small brown spots or red welts on the fabric.
  • Don’t put your luggage on the bed or floor if you suspect your hotel room has bed bugs. Instead, place it on luggage or in the bathroom. Bed bugs love warm places.
  • When traveling, keep your clothes in a sealed bag until you wash them. It will prevent bed bugs from hitchhiking into your home on your clothing.
  • Be vigilant when staying in public places where bed bugs could be present, such as libraries, movie theaters, and buses. Check for signs of bedbugs before sitting down or taking off your coat.
  • Make sure your bedroom isn’t cluttered with things that bed bugs can hide in.

  • Having cracks or crevices in your walls or floors where bed bugs can hide is often the case in older homes or apartments.
