When an exterminator treats bed bugs, chances are he'll use insecticides to take them down.  There are a lot of chcemicals he might use, and it is important that you, as an informed consumer, understand what the options are.  This article contains a listing of the common pesticides for use against bed bugs. 

First off, let me say that I am not a pest control professional, and the information presented here is for informational purposes only. There are many companies constantly working on new chemicals for the bed bug epidemic, so there may be new chemicals out since the time this was written. Consult a trained and certified pest control professional to get the latest information on the most effective bed bug insecticides for your situation.

In general, there are four types chemicals that are used against bed bugs.

• Natural pyrethrins. Pyrethrins are made from chrysanthemum flowers, which are grown especially for their insecticidal properties. Pyrethrins are considered to be among the safest insecticides for humans, though they can cause eye, skin and respiratory irritation. Because natural pyrethrins break down fairly quickly, they will put a dent in the bed bug population, but tend not to have the residual effect necessary to kill off an infestation.

• Synthetic pyrethrins. These are chemicals with names like deltamethrin and lambda-cyhalothrin. These have longer residual effectiveness and are generally water-based, so they are less likely to damage furniture or wood than their oil-based natural pyrethrin cousins.

• Inorganic materials, like diatomaceous earth, silica and boric acid. These will last long, and don’t drive bugs away (which you don’t want – you want them to take a good, deep dose of the bug killer and die). They kill by mechanical action – scratching open the bug’s skin so it dehydrates. They are good for cracks and crevices, but have to be used in a low-humidity environment. Can leave a whitish film on surfaces.

• Insect growth regulators (IGRs), such as hydroprene. These don’t generally kill the bugs, but instead disrupt their reproductive cycle, so they cannot lay viable eggs.

Some studies have shown that some bed bugs developing resistance to some of the common synthetic pyrethroid insecticides.

This is a listing of some of the more commonly used bed bug pesticides. States have varying restrictions on their use, and some of these may not be allowed where you live. I have included the active ingredients and EPA registration numbers to make it easier for you track down information on them.

• Sterifab

• Active ingredient phenothrin with ispropanol

• EPA Registration Number 7401-449
• A DE-based product, can be used on beds.

• Onslaught

• Active ingredient: esfenvalerate
• EPA Registration Number 1021-1815
• Low odor. Microencapsulated, which means pesticide is released over a long period, creating long residual killing power.

• EPA Registration Number 2724-351
• Should be used with other insecticides. Disrupts the development of immature bed bugs, and prevents nymphs from reaching adulthood. They become sterile and are unable to reproduce.
• Can inhibit insect growth for as long as to 120 days.

• Demand CS

• Active ingredient: lambda-cyhalothrin
• EPA Registration number 100-1066
• A popular bed bug insecticide, Demand CD is microencapsulated, meaning longer lasting residual effect. Liquid, applied as a spray. Not to be used on furniture or mattresses.

Your bed bug exterminator may also use an insecticide such as Phantom (EPA Reg Nr 341-392) or Saga WP (EPA Reg Nr 432-755) that is not directly advised for use with bed bugs, but can be effective in killing them nonetheless.
