What Are Roach Bombs?

Cockroach bombs or foggers, also known as total release foggers, spray a mist into the air composed of microscopic droplets of water carrying a pesticide payload. Fogging is effective for killing roaches on countertops, floors, and other flat surfaces.

However, contrary to the claims on virtually all the cockroach foggers on the market, the mist does not reach into the cracks and crevices where roaches spend most of their time. Random air currents may carry some into the cracks, but that’s it.

How Do Roach Bombs Work?

Foggers work based on cubic feet. Each can will be labeled for so many cubic feet. If a label rates the can for 1,000 cubic feet of a room and the room you need to fog is 900 cubic feet, then one can will be sufficient.

If you need to fog a large area of 2,000 or 3,000 cubic feet, you’ll need 2 or 3 cans respectively. Always be sure you know the cubic feet of the area to be treated before you buy, otherwise, you won’t have enough and you’ll just chase the cockroaches from one place to another.

Also remember, a fogger is only intended to work inside in enclosed spaces. It cannot be used outside or the mist will simply drift away and be useless. Furthermore, it is a violation of the label to use an indoor fogger outside.

The label on all pesticides isn’t simply a list of manufacturer suggestions. Pesticides are highly regulated, including the label on each product. According to the EPA, the label is the law. Using a fogger outside is against the law and will get you in a lot of trouble.

Are Roach Bombs Effective?

As long as you understand the limitations of them, yes. Most roach bombs use pyrethroids such as Cypermethrin or Permethrin as the active ingredient for roach control. Pyrethroids will kill a wide variety of house flies, flying insects, and waterbugs.

Some roach bombs may list pyrethrins as the active ingredient while others may list a Pyrethroid as the active. Despite the similarity in their names, pyrethrins and pyrethroids are actually somewhat different.

Pyrethrins are concentrated pyrethrums, natural insecticides extracted from chrysanthemums and other flowers. Pyrethroids are synthetic, man-made versions that are cheaper than botanical insecticides such as pyrethrins.

Pyrethrins, extracted from flowers, have been used for centuries for pest control. Since foggers contain man-made versions of them, they are an effective roach killer – for adult roaches.

There is no such thing as a pesticide that will kill an insect egg. Instead, manufacturers will add an Insect Growth Regulator (IGR) to a pesticide to interfere with the growth of roaches, fleas, and other insects so they can’t mature and lay more eggs.

The best roach bombs will include a synergist such as Piperonyl Butoxide. A synergist is any chemical additive that makes the active ingredient more effective at killing pests than it would be on its own.

How To Use A Roach Bomb

This is where most people fall down. The preparation before using a roach bomb is nearly as important as which fogger you choose. If you’re not willing to do the prep work, don’t bother buying the fogger. It won’t work without it.

We’re not trying to be mean or ugly about it, but if you want good results, you have to follow all the steps.

  • Clean Up

The first step is to clean out all the cabinets, drawers, and shelves in the kitchen and bathrooms. ALL of them.

Without exception.

We know it’s a big job. It’s almost like moving, but it has to be done because the fog won’t penetrate between the plates or under the pots and pans or between the silverware. It will simply land on the top layer where the roaches don’t like to go anyway.

Roaches prefer to be sandwiched between layers over and above them. It makes them feel safe from birds which are their natural predators. They’ll hide under the dishes and other cracks and crevices, safely protected from whatever brand of fogger you’re using.

Once the mist has settled, they’ll come back out. Some will be killed by the residue but many won’t and you’ll still have an infestation to deal with.

  • Wipe Them Down

Use a wet cloth to wide down all the shelves and drawers. Roaches leave little dark specks of their feces laying around and they can eat their feces for food (nasty aren’t they?). Wipe away all traces of them before using the fogger.

Never wipe the shelves and drawers after you fog the house, otherwise, you’ll be wiping away all the pesticide residue and you’ll have wasted your money. You want as much residue as possible to remain in place to kill the bugs.

  • Cabinet and Drawers

Leave all of the cabinet door wide open. Roaches love to hide in the hinges. If the doors are closed the mist won’t be able to penetrate into the hinges and the roaches will be unaffected by it.

Leave all of the drawers standing wide open as well. The mist will settle down like microscopic rain and if the drawers are closed, none of it will get inside them. Those drawers will then become a safe haven for the roaches to get away from the pesticide.

  • Setting the Bombs

Close all the windows in the house. Turn off the A/C and heater, otherwise, it will recirculate the air when it comes on, reducing the amount of mist in the air.

Put each fogger on a piece of newspaper in the middle of the room. If you’re fogging multiple rooms, active them one room at a time, starting in the room that is furthest from the front door. Gradually move through the house, triggering them one at a time.

Once all of them are spraying, leave the house and close the door behind you. Stay out of the house for 2-4 hours. Some foggers have a built-in odor neutralizer but many don’t. The odor in the house may be quite strong, requiring you to open the windows and let the house air before going back inside.

  • Wash The Dishes

Before putting the dishes back on the shelves and drawers, wash all of them with soap and hot water. This removes any traces of the roaches and their odor, confusing them about where a good hiding place is.

Bugs often follow pheromone and scent trails to find their hideouts and safe places. Without any scent to follow, they’ll have to start exploring all over again from scratch. This will force them to move around, which increases their exposure to the pesticide residue.

Are Roach Bombs Safe Around My Pets And Children?

No. Pesticides are normally safe around adults but children have immature bodies, especially their lungs, that can be adversely affected by the fumes. Many pets, such as dogs and cats, are also susceptible to pesticide chemicals, even the botanical ones.

Fish and birds can be killed outright by pesticide fumes.

Remove your children and pets from the house while pesticides are being used and for 2-4 hours afterward. Additionally, open the house and let it air out for at least an hour before allowing your children and pets back in.

Final Thoughts On Roach Bombs

Roach bombs – foggers – are a DIY solution to killing bugs of all kinds. If you use them correctly, you won’t have to pay a pest control professional to come into your house.

If you’re willing to do prep work, the right fogger will take care of your bug problems at a fraction of the cost of calling the bug man.

Each can will treat 5,000 cubic feet, which is a 25 x 25-foot room with an 8-foot ceiling (625 square feet). This product is flammable so you need to turn off all the pilot lights in the house before using it.
