Egg
House gecko eggs develop in a protected location.
Inspection considers shelter and access, not just a visible animal.
Example: a house gecko develops from egg → hatchling → juvenile → adult. This is not insect metamorphosis. Reproduction differs between lizard species. Diagram is schematic, not to scale. Timing varies with species, temperature, food and local conditions.
What keeps them going?
How they feed
House geckos are predators of insects and other small animals. Insects gathering around lights can create a feeding opportunity close to an entrance.
How they survive
Protected gaps provide shelter. Warm conditions and a continuing supply of prey can make a building attractive. Outdoors, lizards can help control insects.
How do they reach your premises?
Open windows, damaged screens and unsealed gaps can let them indoors. A persistent insect problem can encourage repeat visits even after an individual lizard has been removed.
Openings around doors, windows and services provide access. Insects gathering around lighting can offer food, while wall gaps and quiet storage areas provide shelter.
Signs worth investigating.
- Repeated sightings on walls, around lights or near windows.
- Small droppings, often with a pale tip; identification should be checked.
- Gaps, damaged screens or visible insect activity near entry points.
A sign is a reason to inspect, not proof of the species or extent of activity.
Control that addresses
the source.
Reduce indoor insect activity, close appropriate entry gaps and discuss humane removal of animals found inside.
- Inspect openings, screens, shelter and insect activity.
- Prioritise exclusion and repairs suitable for the building.
- Discuss humane removal of lizards found indoors.
- Address the insect attractants through a separate appropriate plan.
- Review entry points and new sightings with the site team.

Lizards are insect predators and can be beneficial outdoors. Keeping them out requires attention to the building and their food supply; a lasting “lizard-free” promise would be misleading.
We agree the preparation, treatment scope and review points for your premises. Method, timing and follow-up depend on the confirmed pest, access and response to treatment.
Why a problem can continue.
- Treating lizards as if they were a routine insect-spraying problem.
- Ignoring insect activity around lights and entrances.
- Removing one animal without repairing the entry route.
Make it harder to return.
- Maintain insect screens and close unnecessary openings.
- Reduce insect attractants, food debris and clutter.
- Review exterior lighting near entrances and repair visible gaps.

Questions we can help with.
Do you need to spray for lizards?
Not as a routine first step. Inspection, exclusion and reducing insects are usually more useful.
Why do they keep appearing near lights?
Lights can gather insects, which provide food for lizards.
Can every lizard be permanently eliminated?
Outdoor populations can continue to approach a building. The aim is to reduce indoor entry and attractants.
