Catford · increase confidence before intervention

Move from a reported sign to a source you can act on.

A sound, bite or brief sighting deserves attention, but it may not support immediate treatment. We build confidence with physical evidence, repeat detections and a credible harbourage or route.

  • Uncertain reports handled without guesswork
  • Monitoring used to answer defined questions
  • Treatment matched to confirmed extent
Technician assessing pest evidence at a Catford property
Four rungs of confidence

Each rung supports a different next step.

  1. REPORT

    A sound, bite, smell or fleeting sighting

    Record the exact room, date and circumstances. Avoid naming the pest before a specimen or matching physical evidence exists.

  2. SIGN

    Droppings, damage, tracks or a specimen

    Photograph position and scale, retain samples safely, and distinguish fresh findings from historic marks.

  3. PATTERN

    Repeated or linked detections

    Monitoring and dated observations can show direction, extent and whether separate rooms are genuinely connected.

  4. SOURCE

    Confirmed harbourage, entry or breeding material

    Treatment and corrective work can now target a supported cause instead of every possible risk.

Do not skip a rung

Common reports that need better evidence.

Catford includes houses, estates, flats and town-centre businesses; the individual property still determines what can be concluded.

Bites

No insect has been found

Skin reactions cannot reliably distinguish bed bugs, fleas or non-pest causes. Inspection considers sleeping areas, pets, travel, furnishings and physical signs before preparation is issued.

Seek identification, not a broad spray
Noise

Movement seems to be above a ceiling

Time and position are compared with droppings, gnawing and accessible routes. Sound alone does not separate mice, rats, squirrels or movement outside the building.

Look for a matching sign
One insect

A specimen appears near food or a window

Species and position decide whether storage, a drain, flying entry or warm equipment should be examined. Retain the specimen rather than clearing every cupboard.

Let identity direct the search
Monitoring with a question

A monitor is useful only when its result changes a decision.

Placement, duration and review point should test a specific uncertainty. Random traps can miss the route, disturb occupants or create a misleading absence of evidence.

Programme-specific follow-up

Continue, adapt or close the work

Confidence does not remove safety limits

The source still has to be reachable and treatable.

A credible rodent route inside a locked riser requires authorised access. A suspected nest high on a roof may need a separate access assessment. The record distinguishes an evidence-supported theory from a space that has actually been examined.

Occupied homes require consideration of children, pets, allergies and vulnerable residents. Food businesses need protection of ingredients, equipment and customers. These constraints influence product and timing without weakening the evidence standard.

Corrective work follows relevance. A leak beside confirmed cockroach harbourage, a damaged door on a rodent run or exposed breeding material for flies can receive priority. Unrelated cosmetic defects do not become pest work merely because they are visible.

At review, confidence is reassessed from fresh evidence. The programme can continue, change direction or close; a fixed number of visits is not substituted for the behaviour and lifecycle of the confirmed pest.

Help us move up the ladder

Bring the strongest evidence you can collect safely.

Give the complete postcode, floor, affected room and best entrance. Mention landlord, concierge or site-manager access, plus previous sprays, traps, cleaning or repairs.

CAPTURE

Photograph context and scale

Show the surrounding surface as well as a close view, without climbing or handling hazardous material.

RETAIN

Keep a specimen securely

Use a sealed clear container labelled with date and room, away from food, children and pets.

LEAVE

Protect the original position

Avoid moving infested items, monitors or suspected entry points before receiving relevant advice.

Questions about confidence

Catford pest-control decisions.

Can bites alone confirm bed bugs?+

No. Bites can have several causes. Inspection looks for live insects, spotting, cast skins and a pattern around beds or other resting places before treatment is selected.

What is the purpose of pest monitoring?+

Monitoring should answer a defined question, such as which route is active, whether rooms are connected or whether treatment has reduced activity. Its position and review date are recorded.

Are old rodent droppings proof of current activity?+

They show that activity occurred, but freshness, later droppings, gnawing, tracks and monitor results help establish whether the route remains active.

When should a treatment area be expanded?+

When matching detections, a credible connection or movement of an affected item supports inspection beyond the original room. Adjoining space alone is not sufficient.

What if the suspected source cannot be opened?+

The access limit is documented and the appropriate landlord, manager or key holder should be arranged. Monitoring may be used, but an inaccessible space is not described as confirmed.
