Why do pests appear even in newly constructed buildings? The most common reasons

There is a common misconception that pest problems are only common in old, poorly maintained buildings. However, practice shows the opposite – mice, cockroaches, mealybugs or ants are increasingly found in newly built homes, offices and commercial premises .

A new building does not automatically mean protection against pests. Quite the contrary, certain factors can actually increase the risk.

1. Cavities and cracks formed during construction

In new construction facilities:

  • technological openings for communications remain,

  • pipe passages are not always perfectly sealed,

  • ventilation systems can be left open until complete installation,

  • micro cracks form in structures.

Even a gap of 0.5 cm can be enough for mice to get inside.

2. Construction waste and moisture

During construction:

  • organic waste remains,

  • dust accumulates,

  • the humidity level increases.

This creates excellent conditions for insects and rodents to settle even before the building is put into use.

3. Urbanization of the new territory

When building new quarters:

  • the natural habitat of rodents is disturbed,

  • their nests are destroyed,

  • decreases in food sources in the field.

The result is that rodents migrate to nearby buildings.

4. Modern constructions – more hiding places

Modern buildings have:

  • many engineering systems,

  • suspended ceiling,

  • cavities between walls,

  • underfloor heating systems.

This is an ideal environment to hide and reproduce unnoticed.

5. Intense movement of people

New business centers and apartment buildings:

  • has a large flow of residents or workers,

  • tenants change frequently,

  • furniture and belongings are being moved.

This increases the risk of pests being introduced from other locations.

What are the signs of a potential problem in a new building?

  • Single insects near windows or storage areas.

  • Cracks in the walls.

  • Small feces or footprints.

  • Unexplained odors.

  • Damage to food packaging.

Early response can prevent a larger infestation.

How to protect yourself in a new building?

  • Check and seal all communication openings.

  • Implement preventive monitoring systems.

  • Regularly inspect storage areas.

  • Perform a preventive inspection of the premises.

Prevention during the first period of operation is particularly important.
