Identify the insect and where it was found
Cockroaches generally have flattened bodies and long antennae. Beetles can look similar but have hardened forewings. Young cockroaches resemble smaller adults without fully developed wings.
Some cockroach species breed indoors; others usually live outside and occasionally enter buildings. A name based only on size or a single dark photograph may miss this distinction.
Look for a pattern around shelter and food
Many cockroaches hide by day and forage at night. Repeated sightings, young insects and egg cases can help an inspector locate activity. Kitchens, bathrooms and gaps around appliances deserve attention, but species differ in their preferred locations.
- Record whether sightings are near an exterior door or deep inside the building.
- Photograph insects and any egg cases rather than reporting only a colour.
- Tell the provider about adjoining units and shared utility spaces.
Make food, water and hiding places less available
Keep food and rubbish covered, clean accumulated crumbs and grease, repair leaks and reduce cardboard clutter. Seal appropriate gaps and maintain door sweeps. Sanitation and exclusion are part of control; pesticide use alone does not solve every cockroach problem.
Make the inspection result part of the quote
Ask which species is suspected and whether the job is mainly an indoor infestation, repeated entry or both. A quote should say which rooms or access points the company will inspect and what monitoring is included.
In a multi-unit property, establish who will arrange access and report activity. Compare the proposed coordination, rather than assuming a single apartment visit covers the wider building.
Three questions to take to a company
- Is this an indoor-breeding species or an outdoor visitor?
- What will monitoring tell us, and who checks the results?
- Which repairs or access arrangements are my responsibility?
