Bug vs. Bite Evidence Checker
Skin reactions cannot identify an insect: bites look alike, appear hours later, and often are not bites at all. This tool gives a calm evidence plan — cast skins, fecal staining, droppings, monitors, and photos — to confirm or rule out an infestation.

Questions people ask about this
Can a doctor tell what bit me?
Generally no. Bite reactions vary enormously between people and are not species-specific. Clinicians treat the reaction; identification depends on physical evidence like the insect itself, cast skins, droppings, or fecal staining found in the home.
I have bites but can't find any bugs. What now?
Look for non-skin evidence: rust-colored smears on mattress seams, translucent cast skins, black pepper-like specks, and captures on interceptors or sticky monitors. Also consider dry skin, fabric or detergent reactions, hives, folliculitis, and mites from pets or birds.
Are bed bug bites in a line of three?
That pattern is often repeated but unreliable. Plenty of bed bug feeding is random, and plenty of non-bed-bug irritation appears in clusters. Treat patterns as weak hints, never proof.
