Pest comparisons.
Some of the most consequential pest decisions come down to telling apart pests that look similar. A termite swarmer and a winged carpenter ant call for completely different responses. A mouse and a rat live in completely different parts of your structure. The comparisons below pull each pairing into one page.
Termites vs. Carpenter Ants
Both damage wood. Only one eats it. The diagnostic differences and why they completely change the treatment program.
Read comparisonBed Bugs vs. Fleas
Itchy bites at the ankles can be either. Bite pattern, evidence, and the household clues that tell them apart.
Read comparisonMice vs. Rats
Size matters, but tail length and droppings are the diagnostic. Why the same trap won't catch both, and how the treatment program differs.

Both are roaches; one is a kitchen problem, the other is a sanitation problem. The bait approach for each is different.

In pest control, identification is the highest-leverage decision you make. A subterranean termite infestation calls for soil termiticide barriers or in-ground bait stations — a structural-level intervention. A carpenter ant infestation calls for finding the parent nest, often with bait or void treatment, but does not require the same kind of perimeter system. Treating one as if it were the other wastes thousands of dollars and leaves the real problem unsolved.
The same logic applies to every pair on this page. Take a clear photo, compare against the diagnostic features in the relevant comparison, and confirm before treating. If you're unsure, the pest identifier tool can narrow it down further, and any reasonable pest professional will offer a free or low-cost inspection.
