How to Kill Bed Bugs - Where to Find Them

Bed Bugs tend to hide in dark places such as in cracks or under furniture or light fixtures. Before you can kill them you have to know where to look. Anything you can remove and tie in a plastic bag will keep the item clean as you eliminate hiding places. Common hiding places include:

  • Floors: look for cracks in flooring, underneath your carpets, under molding or baseboards.
  • On Walls: If you have plaster, look in any cracks in the wall. Check for wallpaper that is not firmly glued to the wall. Check around anything attached to the wall such as shelves, mirrors and pictures. Remove all of these if you can to clean behind them.
  • Outlets: Check behind electrical outlets that are not firmly mounted. Check behind any wiring that is on the floor or that runs along walls.

  • Books/Magazines: Check the pages of any printed materials. Bed bugs can hide between pages.
  • Electronics: If there are cracks in your phone or radio, look inside to make sure that bugs haven't entered. Same for computers that have the fan grates in the back.  The only way to kill bed bugs in electronics is to hire a professional that uses a dry ice spray or use heat from a hair dryer or a  portable heat chamber such as PackTite.

Peel back the fabric on the bottom and also treat the inside of the box spring.  If you have some, place some bed bug dust (fossil dust) inside the box spring.

Note, only do this if the mattress and box spring are in good condition and do not have holes. If the mattress is old and torn, or was purchased used, you are better off throwing it out.  When disposing of the mattress wrap it in plastic wrap to avoid dropping bed bugs and mark it as having bed bugs so that someone else doesn't pick it up.  Many town sanitation departments have a free mattress pick up service.

How to Kill Bed Bugs - Types of Products

There are several types of products that are used when figuring out how to kill bed bugs:

Synthetic Pyrethroid: This is an effective choice for a knock down product that kills on contact, but doesn't provide a lasting effect. Sterifab is a popular choice as it kills bedbugs, bed bug eggs and is mattress safe.

Chlorfenapyr: This chemical is quickly becoming the product of choice when selecting a product that provides a residual effect against bed bugs.  It works by entering the cells of bed bugs and causing paralyzes. It provides weeks of protection and is not detected by bedbugs.  Is is the main ingredient in the spray Phantom.  

Multiple Chemicals: Some spray products use proprietary or multiple chemicals.  One of the most popular sprays, Bedlam, uses this approach (contains SUMITHRIN® and MGK®-264).  It is an excellent choice as a residual spray as an alternative to Phantom.

Permetherins: This is the leading insecticide ingredient. While it is considered safe, it is an insecticide that has shown to cause problems in laboratory animals. See this study by Cornell University researchers. Permetherins (pyrethrum) is the active ingredient in products such as Pronto, Ambush, BW-21-Z, Cellutec, Ectiban, Eksmin, Exmin, FMC-33297, Indothrin, Kafil, Kestril, NRDC 143, Pounce, PP 557, Pramiex, Qamlin and Torpedo

Benzalkonium Chloride: A safe alternative to permetherins, particularly for areas that you sleep in or near. Found in products such as Benzarid.

Plant Extracts: Certain organic plant extracts are a safe way to kill bugs within seconds of contact. Found in bed bug products such as Bug Patrol.

Fossil Dust: Dust products can be sprinkled in areas where the bugs tend to hide. It can also be sprinkled into cracks.  This product can be purchased at low cost from Dermisil.

Steam: Steam heat applied directly to the bugs will kill them.  One the low cost end, a good choice is Steamfast, although a proffesional grade steamer is always better.

Portable Heaters: Bed bugs are killed at 113º F. One effective and chemical free approach to killing bed bugs is to super heat a room, or building to kill bed bugs in all objects.

Freezing with Dry Ice Spray: Bed bugs are killed at freezing temperatures.  A system using frozen carbon dioxide or dry ice, is sprayed into cracks and crevices to kill bed bugs on contact.  The technology has an added advantage of being able to be sprayed into electrical appliances and wall outlets, killing bed bugs hiding in these areas.

Bed Bug Dogs: Bed bugs give off a scent that dogs can be trained to detect.  This is a highly accurate way to find bed bug hiding places in a home.  The only downside is the cost of home inspections that use a dog.  If you suspect a problem, but aren't sure, a firm that uses a bed bug sniffing dog can be an effective way to find any problems.

Fumigation: Used a last resort, a building can be fumigated with chemical pesticides to remove bed bugs.  This approach is effective, but expensive.
