As temperatures fall, many companies leave the typical problems of summer behind and assume that the risk of pests also decreases. Autumn, however, is a particularly sensitive time for shops, restaurants, warehouses, apartment buildings and industrial premises. Rats, mice and cockroaches look for food, water and shelter in protected spaces, and a business can provide everything they need before anyone notices their presence.
At Lluita Integral, we see the same pattern every autumn across Girona and the Costa Brava: small warning signs are overlooked until activity becomes visible. A noise in the storeroom, traces near a loading door or a cockroach in a service area may be the first indication of a problem that has already found an entry route. Inspecting the premises early makes it possible to act more precisely and prevent the issue from affecting operations, hygiene or the company’s reputation.
Why pests look for shelter when colder weather arrives
Falling temperatures change the behaviour of many species. Rodents move towards buildings where they can find warmth and protection, while cockroaches use drainage systems, plant rooms, suspended ceilings and damp areas to remain active. They do not disappear at the end of summer; they move into more stable environments.
Businesses are particularly attractive because they often have frequent deliveries, doors that open throughout the day, waste areas, drains, warm machinery and quiet corners. In warehouses and industrial premises, a large floor area can hide activity for weeks. In hospitality and food businesses, even a small source of water or organic residue may be enough to sustain a pest population.
Signs of rats, mice or cockroaches that should not be ignored
You do not need to see several animals before requesting an inspection. Pests usually avoid people and leave evidence before they appear in open areas. Warning signs include:
- Droppings in storerooms, waste areas, shelving or along walls.
- Packaging, cables, cardboard or materials showing gnaw marks.
- Noises at night in suspended ceilings, wall cavities or quiet parts of the building.
- Dark smears and repeated routes along skirting boards or service penetrations.
- Live or dead cockroaches near motors, drains, inspection chambers or refrigeration equipment.
- Egg cases, shed skins or small traces in cracks, furniture and warm spaces.
- Persistent odours that do not disappear after routine cleaning.
A single sign may seem minor, but it should be checked when it appears near food, moisture or access points from outside. Waiting until the infestation is obvious usually increases the scope of the intervention and the disruption to the business.
The critical points we inspect in a business
At Lluita Integral, we do not focus only on the place where the animal was seen. A professional inspection looks for the source, movement routes and conditions that allow the pest to remain in the building.
We inspect loading doors, shutters, pipe penetrations, joints, inspection chambers, drains and connections with neighbouring premises. We also assess storerooms, cold rooms, kitchens, changing rooms, suspended ceilings, plant rooms and waste areas. In businesses receiving frequent deliveries, we check whether packaging, pallets or the movement of goods may introduce or conceal pest activity.
The aim is to distinguish between an isolated entry and an established infestation. This information allows us to recommend proportionate measures and avoids generic solutions that only reduce the visible signs for a short time.
Cleaning helps, but it does not always remove the source
Keeping the premises clean is essential, but a pest problem is not necessarily caused by poor hygiene. Rats can enter through a structural opening, while cockroaches may travel through the drainage system or arrive with deliveries. Cleaning removes available food and makes detection easier, but it cannot fix a poorly sealed door, an active inspection chamber or a harbourage inside a suspended ceiling.
That is why we combine technical inspection with practical recommendations. The business may need to improve door seals, reorganise storage, repair leaks, protect drains or adjust waste management. If activity is confirmed, we add the appropriate control and monitoring measures to ensure that the problem is decreasing rather than moving to another area.
How Lluita Integral manages autumn pest control
Our process begins with an inspection of the premises and a clear conversation with the person responsible. We collect reports from staff, locate critical points and confirm which species is present. We then prepare a plan suited to the type of premises, the level of risk and the activity carried out there.
The intervention may include monitoring, secured control stations, traps, targeted baits, localised treatments and exclusion measures. In food, retail or public-facing environments, we work effectively and discreetly, paying particular attention to safety, traceability and business continuity.
Where necessary, we schedule follow-up visits to assess activity, captures, consumption, new signs and any corrective work still outstanding. This follow-up shows whether the strategy is working and helps prevent a new entry point from restarting the problem.
Prevention now can avoid an emergency in winter
The best time to inspect a business is before a pest becomes visible to customers, suppliers or employees. A preventive autumn inspection helps identify entry points, organise monitoring and correct favourable conditions while there is still time to act calmly.
Lluita Integral provides professional pest control services, rodent control and insect control for businesses, shops, apartment buildings and other premises in Girona and the Costa Brava.
