Foggers are pest control products that spread insecticide by creating a type of mist. They are one of the industry’s top tools in fighting large roach infestations in a short period of time.

There are a number of product types available in the market to control cockroaches: sprays, roach powders, baits and baits stations, and gel baits.

However, foggers are an effective choice for large scale results. If you are moving to a new place with a severe roach infestation, it’d be better to simply “fog” the house before using other more nuanced control methods.

Frequently Asked Questions

Do foggers or bug bombs work on roaches?

It is one of the most frequently asked questions we receive and the simple answer is this: Yes, foggers or bug bombs do work provided you use the right product according to your situation. For instance, you should know the type of infestation you are dealing with and the surface area you want to cover as some foggers cannot a large room, and as a result, their performance will decrease. Similarly, most insecticides work when they come in direct contact with the insect. Therefore, it should be made sure that you choose the right fogger which goes deep down into hidden areas of roach infestation. Otherwise, you may not get satisfactory results.

Are roach foggers completely safe for humans and pets?

The answer to this question without a doubt is: NO! Foggers or roach bombs are not safe for humans and other mammals—they contain chemical substances which upon entering our system via inhalation or contact by skin, can cause allergic reactions. Therefore, necessary precautions should be taken to safely use such products; this is also one of the main reasons that homeowners prefer other roach killing methods such as sprays, baits, and bait stations.

Why do house needs to be cleaned after using a fogger?

A very important yet crucial thing to keep in mind after using a fogger of any kind is to clean the surroundings thoroughly; which means that every hard or soft surface should be properly cleaned after the fogging, even if the fogger had a dry formula, unlike those which leave residue behind after using. This is advised on the label of the product as well. Foggers contain certain active ingredients which might be harmful for humans or pets and can cause irritation or allergic reaction upon coming in contact with the skin.

Can foggers be detected by smoke alarms in home?

Yes. It is best to turn off smoke detectors before using the roach bomb or fogger as you do not want to have to go back into the room to shut off a beeping smoke detector once the product has been deployed.

How can a roach infestation be avoided in homes?

A roach or any insect infestation can become unbearable to live with. By making small alterations in household habits, those problematic infestation problems can be avoided. Such as:

  • Remove food spills and exposed foods.
  • Always try to store food in sealed containers.
  • Try to avoid leaving dirty dishes in sinks.
  • Do not keep food in bedrooms or living rooms.
  • Seal any voids, spaces, cracks and crevices, including entry points from outside or neighboring units from where insects can come into a room.

The Environmental Protection Agency lays out the following guidelines for safely using foggers:

  • Do not use more foggers than necessary
  • Keep foggers away from ignition sources
  • Notify family members, neighbors, and anyone else that may enter the premises
  • Vacate the treated house, individual apartment unit, or other structure immediately
  • Air out after returning to the treated area

Our Final Thoughts On Roach Foggers

Generally, roach foggers are used when there is a need for combating a large roach infestation problem in less time. They do provide efficient results with a single use only.

However, unlike other roach killing products, foggers only kill insects where the product is used. These are not meant for treating the entire colony of roaches somewhere else in the house.

In addition, it should be kept in mind that foggers are a bit harder to use and come with a set of instructions, which if not followed can be harmful for humans or pets. Injuries can be avoided though by reading the instructions provided on the label of your chosen product.
