"Bed bug repellent choices vary based on if you need one for your body such as when sleeping, for luggage to protect against bedbugs when traveling, or when protecting your home or apartment from bed bugs. Reviews of each bed bug repellant are provided below "
Today, the most popular insect repellent is DEET. It is the main ingredient in name brand products such as Off (95% DEET) and Bug Barrier Insect Repellent (100% DEET). Research has shown that products with high concentrations of DEET (97%( show 93 and 83 per cent repellency after 2 and 8 hours respectively.
There is an all natural alternative that has a 98.5% bed bug repellant rate. The product, correctly named Bed Bug Repellent, is made of plant extracts that are known to have properties which repel bed bugs.
Given the choice, the natural product has the edge for protection against bed bugs when sleeping.

Just about every traveler worries about bed bugs. A
spray designed for luggage can help reduce your chances of bringing
them home with you. For travel, we suggest the insecticide
based JTEaton
Bedbug Spray for Luggage and Mattresses. It uses
permethrin as the active ingredient. If you prefer all
natural products, then the suitably named Bed
Bug Luggage Spray is also a good choice.
JTEaton Luggage spray will protect against bringing
home many types of insects in addition to bed bugs including roaches,
fleas, ticks, louse eggs and lice from jumping on board your luggage.
Spray before packing. It will protect luggage,
backpacks and other travel items for 3 to 6 weeks.

Protect yourself when traveling by using a bed bug proof luggage liner. It keeps bed bugs from getting into your luggage, the most common way bedbugs get into a home.

Another approach is to pack Ziploc Big Bags and then place your clothes into the big bag. Pack the entire bag with your clothes inside your luggage. If you have a small carry-on, you can seal the entire piece of luggage in a Ziploc when you arrive at your hotel.

Keep luggage on racks and off the floor for added bed bug protection.
Most bed bug sprays are formulated to kill bed bug eggs and bed bugs on contact, not repel them away from the person or object being protected. The products mentioned above such as JTEaton or BedBug Repellent can be used as a bed bug repellant on furniture, mattress, luggage and backpacks.
Most bed bug sprays are not formulated to repel bed bugs, but
allow them to enter the treated area without being detected.
The best product for this purpose is Phantom,
which will kill bed bugs for several weeks. It cannot be
used directly on mattress surfaces, and is best left for the box
spring, baseboards, and furniture (NY residents cannot purchase Phantom
and should use Bedlam
instead). We recommend both of these products if you live in
an apartment and are trying to keep bed bugs from spreading into your
home.
The best general use and mattress safe product for killing bed bugs on
contact is Sterifab
(insecticide based) or Bug
Patrol (natural/organic). These products are best used when
you have a bed bug problem and are trying to kill them as part of a
treatment program.
