The field guide
Working notes on the line: what the regulator actually does, how the tank gets mixed, where the discs go, and how a treated room behaves over the following weeks.
What an IGR actually does
Hydroprene does not touch the adults walking the floor. It reaches the brood behind them, and the molts start going wrong. Here is the mechanism.
Mixing one ounce per gallon
The whole recipe for Gentrol IGR Concentrate is one ounce in one gallon, and that gallon walks 1,500 square feet. The rest is where to point the wand.
Where point source discs go
Each station covers about 75 square feet of enclosed space. Placement decides whether that coverage lands where the nymphs are. Here is how we place them.
Crack and crevice with the aerosol
The foam is visible on purpose, the straw is the real applicator, and one 16 oz can walks about 1,200 square feet. Technique notes from the bench.
Keeping a commercial kitchen clear
Drains, dish lines, dry storage and a staff that works around all of it. How the four Gentrol formulations divide a commercial kitchen between them.
What 120 days of control means
The number on the can describes how long the active keeps working in a treated void. What it means for scheduling, and what it never said about day one.
