Mosquitoes in apartments and houses – recognize, understand causes & properly control

Mosquitoes are among the most common and at the same time most annoying insects indoors. They occur in private households as well as in hotels, gastronomy, and offices. Besides itchy bites, they disturb sleep and reproduce quickly under suitable conditions.

On this page, you will learn how to recognize mosquitoes, why they come into the house, and which measures for self-control really help.

What are mosquitoes?

Mosquitoes are biting insects. Only the female insects need blood to produce eggs. They are guided by body heat, odors, and exhaled CO₂ and are mainly active at dusk and at night.

Typical characteristics:

  • slender body with long legs

  • audible buzzing

  • bites with redness/itching

  • strong attraction to light, warmth, and odors

Typical infestation sites

Mosquitoes are especially common in:

  • Bedrooms and living rooms

  • Kitchens and bathrooms

  • Basements

  • Balconies, terraces, and gardens

  • Areas with standing moisture

They usually enter the building through windows, doors, or ventilation openings.

How to recognize a mosquito infestation?

Common signs:

  • itchy bites on uncovered skin

  • nocturnal buzzing

  • visible insects on walls or ceilings

  • increased occurrence in warm rooms

  • recurring mosquitoes despite ventilation

Multiple bites almost always mean: multiple insects.

Why do mosquitoes come into the house?

The most common causes:

  • open windows without insect screens

  • Light sources in the evening

  • standing water (e.g., saucers, watering cans, buckets)

  • warm indoor spaces

  • damp basements or bathrooms

Even the smallest amounts of water are enough for mosquitoes to reproduce.

Are mosquitoes dangerous?

In Central Europe, mosquitoes are mostly just annoying. However, they can:

  • Cause severe itching

  • Cause sleep disturbances

  • can cause allergic reactions in sensitive individuals

The key factors are mainly the loss of comfort – and the rapid reproduction under favorable conditions.

What really helps against mosquitoes?

Home remedies like scented candles or plants usually only work short-term.

Proven effective are:

  • targeted mosquito traps or electric insect catchers

  • Sprays/repellents for indoor use

  • Removal of breeding sites (consistently eliminate standing water)

  • Fly screens on windows

  • Combination of control and prevention

Sustainable control arises from the combination of trapping, deterrence, and prevention.

Typical duration of control

Depending on the number of insects and environment:

  • initial reduction often within a few days

  • significant improvement after 1–2 weeks

  • lasting result through consistent prevention
