MODE – OF – ACTION. Pest control professionals talk about this when choosing chemical eradication and maintenance for pests. I’ll bet you didn’t consider that your doctor uses the same systematic thinking when prescribing medication for illness. By a show of hands, How Many Of You Know What It Means?🙋♀️
Let’s break it down.
MODE – The manner, or way in which something occurs, is done, or expressed.
ACTION – The accomplishment of a thing done over a period of time, in stages.
MODE OF ACTION – The accomplishment you get, over time, by using a certain manner, in stages. Sounds a little like Integrated Pest Management (IPM), huh?

I’m sure you just skimmed the title of this post. Look at it again. My reference was to the IRAC Chart. The actual meaning of those 4 letters: Insecticide Resistance Action Committee.
This scientific language looking graphic has a wealth of information. To the lame eye, it’s mind boggling. What’s contained within its colored boxes is a manual for getting a handle on insect, rodent, or other pest issues.

When choosing an insecticide, complete understanding of chemical compounds is not necessary. The main focus for the Certified Applicator should be that each box represents a MoA. By corresponding this information to a product label, one can identify when it’s time to switch from Group 1B to Group 3A to Group 8D to Group 24A. Sometimes, you will want to add Group 7.
When taking the IRAC + IPM approach, that commitment will signal to pests that change is eminent….ready or not.
