Fogging

Fogging is the use of a pesticide in a ULV or ULD form. ULV and ULD stand for Ultra low Volume and Ultra Low Dosage. These terms refer to the droplet particle sizes generated. The micron size particles generated vary from 5-50 microns.

Indianmeal moths, flour beetles, and flies are the insects most commonly targeted for fogging, but they are not the only ones. The fogging particle attaches to the hairs on an insect. Through capillary action the particle wicks into the thinnest part of the exoskeleton at the base of the hair. It reaches the insect by contact. Fogging is not a fumigation, and the same results should not be expected.

Fogging is not some kind of cure all for insect problems. Fogging is a supplement to proper sanitation and is much more effective when dust and dirt particles are removed.

The need to fog can be determined in a couple of ways:

  1. Routine inspections - you should be looking in cracks and crevices and hard to reach areas where a food source is readily available.
  2. Pheromone monitoring – when pheromone traps show population growth, it is time to take action.

Fogging Safety Equipment

Fogging requires safety equipment. Always read the most current label and SDS before purchasing and using any fogging agent. Many fogging agents require the following: cotton disposable suit, rubber gloves, chemical goggles, rubber boots, pants, long sleeved shirt, and full face mask with Organic Vapor filter. Vapona requires additional safety precautions such as a Self Contained Breathing Apparatus (SCBAs) and warning signs on the building during treatment. Safety equipment should be worn while pouring, mixing, and fogging with all fogging agents.

There are many foggers on the market to choose from. Determine which foggers to purchase by the volume of space you will be fogging. Gasoline, propane, and electric models are available. Always check the micron size particles generated and the micron size particles needed for your fogging agent before purchasing your fogger.

When you fog, or sub-contract someone to fog, you should have a quality control measure. Many people use bioassays, or “BugChecks” in their facility during a fumigation, you can use FogChecks to test the efficacy of the fogging. You simply place the fogchecks in the area to be fogged, usually in main problem areas, and pull them out after the job is completed. Fogging is only effective on exposed insects, so you must place them where they will be exposed.

Finally, fogging is a cost effective way to knock down insect populations. Fogging is not a fumigation and the same results cannot be expected. Proper sanitation greatly aids the efficacy of a fogging and “bug checks” can ensure a proper job was done. Fogging does require safety measures, so always read the latest label and SDS before applying.
