Find out where they are
First, you need to find out exactly where the bed bugs are so that you can target treatment. If you're getting bitten while sleeping, check the mattress. If it's from sitting on the couch, uncover the throw pillows and cushions to see where they're hiding.
Bed bugs can also be found inside dresser drawers, between the wallpaper, and in the corners. They can even be found around electrical outlets, so long as the crevices are tight enough for them to hide in. Finding exactly where they're hiding helps you narrow down your treatment and determine where you should be targeting.
Clean, wash, and sanitize everything
Once you've found where the bed bugs have been hiding, it's time to clean or get rid of everything they have touched. For bed sheets and curtains, wash them in hot water or get them dry cleaned.
Mattresses are some of the most common places bed bugs are found. If you want to continue using the mattress, clean out the seams and crevices and encase it with a plastic sheet. This prevents bed bugs from embedding themselves within the mattress.
For furniture that has been damaged by bed bugs, take a vacuum cleaner with a detachable nozzle and run it across the surface. Make sure to get the corner and seams where they are most likely to hide.
Seal up cracks, replace the wallpaper
Next, work on the exterior of the home. Cracks around windowsills and doors give bed bugs another option for hiding. Fill in these areas with caulk to prevent further bed bug hiding spots.
Bed bugs are also known to inhabit the tight space between the wallpaper and the wall. You might notice the wallpaper peeling at some point, and it may be from bed bugs. Clean out these areas with a vacuum cleaner and replace the wallpaper. If possible, try using synthetic material for the paper and the glue.
Prevent, prevent, prevent
After you've taken the steps to identify, clean, and patch up the different problem areas, do everything you can to prevent it from happening all over again. Bed bugs are attracted to dark and hidden environments that enable them to hide and thrive within close vicinity of humans. Avoid this by keeping your home clean and in good condition and checking your sheets periodically.
Vacuum the carpets at least one a week or every two weeks; take out the trash, wash or dry clean all linens and most of all, keep living areas dry and well-ventilated. This way, you'll avoid bed bugs, one of the most unsightly pests out there, and keep your home in a great, livable condition.
