Mosquitoes: Recognize & prevent sustainably

Mosquitoes are primarily active during the warmer months and can be very annoying due to their bites. They reproduce in standing water and find ideal breeding conditions in gardens, on balconies, and even in the house. Here you will find out how to recognize mosquitoes, reduce their breeding sites, and sustainably curb an infestation.

What are mosquitoes?

Mosquitoes belong to the Culicidae family. Only female mosquitoes bite, as they need the blood for egg laying. The larvae develop in water – even small amounts are enough to produce many new mosquitoes within a short time.

Mosquito Breed in water seasonally active

Important: Mosquitoes do not appear "by chance" – almost always there is an undiscovered accumulation of water nearby where the larvae develop.

How to recognize a mosquito problem

increased mosquitoes in the house or garden
itchy bites, especially in the evening and at night
mosquitoes hatch again and again despite closed windows
buzzing at dusk or at night

Green Guardia Tip: Check flower pot saucers, watering cans, rain barrels, and drains regularly – just a few days of standing water are enough for the development of larvae.

Typical breeding sites

flower pot saucers
rain barrels, buckets, watering cans
clogged gutters
ponds without circulation
drains and damp basement areas

Why is there a heavy occurrence?

warm weather & high humidity
standing water outdoors or indoors
lack of natural antagonists
open windows without insect protection

What to do against mosquitoes? (natural & sensible)

1. Consistently remove breeding sites

empty standing water regularly
cover rain barrels
keep saucers dry

2. Bring movement into the water

use pond pumps or small water features
larvae do not like moving water

3. Make access to the house difficult

fly screens on windows & doors
ventilate purposefully in the evening

Natural antagonists & support

In natural gardens, birds, bats, and aquatic organisms (e.g., dragonfly larvae) help to regulate the mosquito population. The most important step, however, remains: Remove breeding sites.

Why prevention is decisive: If no larvae can develop, no new mosquitoes are created in the first place – that is more sustainable than any short-term measure.

FAQ about mosquitoes

Why do some mosquitoes bite more often?

Mosquitoes react to body odor, CO₂, heat, and skin bacteria – some people are therefore more "attractive" to mosquitoes.

Does light help against mosquitoes?

Light alone hardly attracts mosquitoes. Smell and breathing air (CO₂) are more important.

Are mosquitoes dangerous?

In our latitudes, they are "mostly" annoying, but harmless. Bites can, however, itch and become inflamed.

How can I prevent them?

Avoid water accumulations, use fly screens, and check breeding sites regularly.
