As temperatures rise, there is a pattern that repeats itself in many homes: the unexpected presence of several flies, especially in rooms like the kitchen. The phenomenon may appear to appear suddenly, but it is generally linked to behaviors typical of this time of year and conditions that favor the presence of these insects indoors.
According to , which cites statements by entomologist Richard Wall to HuffPost, the explanation for this increase is not complex. The expert points mainly to a common habit on hot days: keeping windows and doors open for longer, making it easier for flies to enter.
An effect associated with heat
The high temperatures that are felt in several European countries lead to an increase in natural ventilation in homes. Opening windows becomes a necessity to cool internal spaces, but this gesture simultaneously creates a direct access route for insects.
Even though the presence of several flies may seem abrupt, the reality tends to be more gradual. Continuous entry over hours or days, combined with circulation within the house, makes the concentration more visible, especially in areas where there is food or organic waste.
The role of reproduction
In addition to easier access, heat directly influences the life cycle of flies. In warmer environments, reproduction tends to accelerate, which may contribute to an increase in the number of these insects over time.
However, this process does not happen overnight. Evolution depends on several factors and can take weeks or months to translate into significant population growth. Still, when combined with the frequent entry of new insects, it can reinforce the perception of a sudden increase.
Because they all seem to appear at the same time
The concentration of flies in certain parts of the house also helps to explain the phenomenon. By congregating in specific areas, they become more visible, which can feel like a sudden invasion.
This behavior is often associated with the search for food or suitable places to rest. Kitchens, trash cans or surfaces with traces of food end up acting as points of attraction.
How to reduce presence at home
Prevention is, according to experts, the most effective way to deal with the problem. Installing screens or barriers on windows allows ventilation to be maintained without facilitating the entry of insects. Maintaining cleanliness, especially in areas where there is food, is equally crucial.
There are also homemade solutions that can help reduce the presence of flies. Among them, the use of containers with apple cider vinegar and dish detergent, which act as traps, or the use of odors considered repellent, such as lemon with cloves.
According to Notícias ao Minuto, these strategies can complement preventive measures, but controlling access to the interior remains the most relevant factor in preventing the accumulation of these insects in homes.
