Termite droppings: what to look for →
Firm pellets below a wood opening are worth comparing.
Limit: A pile alone cannot establish current activity.
OBSERVATION KIT / 01
Start with what you can see.
Choose a clue, then add a visible feature. These are reading suggestions, not an identification or a probability score.
Choose a clue to narrow the reading list.
Leave uncertain waste undisturbed
Do not touch, crush, sweep, or vacuum suspected rodent or wildlife waste. Read the relevant guide for qualified next steps.
Not enough detail yet
Try a clear photo of the whole object, its location, and a size reference where safe. Keep an uncertain finding marked uncertain.
How to make a useful evidence photo →Termite mud tubes: how to recognize them →
A continuous earthen tube on a foundation is a useful clue.
Limit: Loose soil on a wall is not automatically a shelter tube.
What termite damage can look like →
Compare the exposed damage and other termite signs.
Limit: A photo cannot show hidden structural condition.
Carpenter ant frass: sawdust-like debris →
Compare expelled wood fragments with termite pellets.
Limit: Debris without an insect or gallery may remain ambiguous.
Carpenter ant damage: galleries, debris, and moisture →
Smooth galleries and nearby ant evidence merit comparison.
Limit: A nearby ant does not locate a nest by itself.
Powderpost beetles: round holes and wood powder →
Round holes plus powder suggest a wood-borer comparison.
Limit: Old holes do not prove a current infestation.
Mouse droppings: signs and safe next steps →
Compare the deposit with the location and any animal actually seen.
Limit: Do not handle or crumble waste to test the species.
Rat droppings: compare signs safely →
Compare the deposit with the location and any animal actually seen.
Limit: Do not handle or crumble waste to test the species.
Squirrel droppings: why pellets alone are not enough →
Compare the deposit with the location and any animal actually seen.
Limit: Do not handle or crumble waste to test the species.
Bat droppings: guano clues and safe next steps →
Compare the deposit with the location and any animal actually seen.
Limit: Do not handle or crumble waste to test the species.
Raccoon droppings: recognizing a possible latrine →
Repeated deposits in one area warrant a wildlife assessment.
Limit: Appearance cannot show microscopic roundworm eggs.
Lizard droppings: a dark pellet with a white portion →
A white urate portion provides context for a gecko comparison.
Limit: A pale fleck alone does not confirm a lizard.
Roach poop and cockroach droppings →
Check the nearby insect and egg-case evidence.
Limit: A dark deposit alone does not confirm cockroaches.
Bed bug stains and dark spots →
Compare physical signs around sleeping furniture.
Limit: Stains and skin symptoms do not independently confirm bed bugs.
Spider droppings: spotting beneath a web →
An occupied web above spotting gives additional context.
Limit: A stain cannot identify a spider species.
Flea dirt: dark specks on a pet or its bedding →
Keep observations from the animal and its bedding together.
Limit: A veterinarian should assess uncertain pet symptoms.
German cockroach: markings and indoor clues →
Look for paired dark lengthwise marks behind an adult’s head.
Limit: The outline or finding room alone cannot confirm the species.
American cockroach: size, color, and lookalikes →
Compare a large reddish body and pale border behind the head.
Limit: The outline or finding room alone cannot confirm the species.
Oriental cockroach: dark body and short wings →
Compare a dark shiny body and short adult wing coverage.
Limit: The outline or finding room alone cannot confirm the species.
Brownbanded cockroach: bands and hiding places →
Compare bands running across the body; life stage matters.
Limit: The outline or finding room alone cannot confirm the species.
Bugs that look like cockroaches: comparison guide →
Compare hard wing covers, antennae, and complete body shape.
Limit: The outline or finding room alone cannot confirm the species.
Water bug vs cockroach: what the name leaves out →
Resolve the nickname by comparing the actual insect and legs.
Limit: The outline or finding room alone cannot confirm the species.
Black carpet beetle: adults, larvae, and fabric clues →
Compare the adult beetle with larval evidence elsewhere.
Limit: A window-sill adult does not locate a feeding source.
Tiny black bugs near windows: a starting checklist →
Record movement, size, and an intact body view.
Limit: “Tiny black bug” is not a species identification.
Silverfish in a house: body shape, eggs, and clues →
Look for a tapered body and three tail filaments.
Limit: Related insects may require closer identification.
Bugs that look like bed bugs: what to compare →
Compare an intact specimen with the common lookalikes.
Limit: Bat bugs may need magnification and specialist examination.
Carpet beetle vs bed bug: compare the actual insect →
Separate a hairy larva, hard-bodied beetle, and flat bug.
Limit: Do not use skin symptoms to settle the comparison.
Baby cockroaches: nymphs and lookalikes →
Compare markings and wing development with the adults.
Limit: Small size alone cannot identify the cockroach species.
Carpet beetle larvae: identification clues →
Compare hairs, cast skins, and nearby material.
Limit: A cast skin is not a live larva.
Pantry moth larvae, eggs, and food webbing →
Look for larvae or webbing associated with stored food.
Limit: A ceiling sighting may be away from the food source.
Cockroach egg cases: what they look like →
Compare a capsule-like case and any nearby cockroaches.
Limit: An object resembling a capsule is not a confirmed egg case.
Bed bug eggs: appearance and hiding places →
Look for associated insects, cast skins, and hiding places.
Limit: Pale debris alone is unreliable.
Carpet beetle eggs: where to look →
Check for larvae and associated material before naming eggs.
Limit: Tiny eggs may require magnification.
Termite eggs and young: what household clues can show →
Record intact insects and other wood evidence.
Limit: Do not open structural wood to search for hidden eggs.
Termite swarmers and shed wings →
Record shed wings and any intact insects.
Limit: An outdoor swarm does not prove a building is infested.
Termite or flying ant? Three clues to compare →
Compare waist, antennae, and relative wing lengths.
Limit: Loose damaged wings can omit the features needed.
