In hot months, flies invade the houses again with a persistence that surpasses the mere inconvenience. These insects, in addition to irritating tinnitus, may pose health risks when transporting bacteria and contaminating food. Many are looking for natural and economic methods to protect themselves from these pests without resorting to chemicals.
The sensitivity of flies in light can be used in our favor
According to Green Vibe, flies have an extremely sensitive view. Their eyes composed of thousands of microscopic lenses allow them to detect even the smallest movements and reflexes. This natural feature, which helps them avoid predators, can be used against them in home environments.
According to the same source, flies tend to avoid places where there are many reflexes of light, especially those that are irregular and moving. When confronted with certain visual stimuli, they become disoriented and eventually move away from the zone where these reflexes are present.
It is based on this principle that a homemade trick arises that has been gaining popularity: the use of aluminum paper to keep flies away. Although there are no specific scientific studies on this practice, visual logic behind the method is documented.
The aluminum trick
According to Green Vibe, aluminum paper is a highly reflective material, which means that disperses light in multiple directions when exposed to a luminous source, whether natural or artificial. For flies, these multiple reflexes are perceived as movements or threats, which leads them to avoid these areas.
One of the most common ways of applying this method is putting aluminum leaves in the zones where flies usually arise more often, such as windows, cooking countertops, fruit or sinks. Another technique consists of shaping small balls with paper and hanging them by curtains or the ceiling, allowing air movement to create intermittent reflexes.
In addition, Green Vibe states that glass bottles can also be involved with aluminum foil and position them near doors and windows. Another suggestion is to combine aluminum with transparent plastic bags full of water, placing pieces of paper inside these bags. This combination enhances the visual effect that confuses flies.

A simple and safe alternative
The main advantage of this method, according to the same source, is that it is completely free of chemicals. Unlike sprays and insecticides, aluminum role does not release toxic substances in the air, being a safe solution for houses with children, animals or people with allergies.
Although aluminum is not biodegradable, it can be reused several times and is recyclable, which makes it a more sustainable alternative compared to disposable methods. In addition, it is an economic, accessible solution that can be easily tested in any home.
It is important to stress that this strategy should not be seen as a substitute for other prevention measures, but as a complement within a broader insect control plan.
Additional measures that make a difference
Green Vibe recommends some good practices to avoid the attraction of flies indoors. One of the most important is to keep all spaces clean, especially kitchens and meal areas. Rests of food, too mature washing and fruit are immediate attractions.
Closing the garbage bags correctly and frequently emptying them helps eliminate odors and waste that attract these insects. Installing mosquito nets on windows is another practical way to prevent your entry, even with windows open during the summer.
The use of plants with naturally repellent properties, such as basil, lavender or mint, can also reinforce protection against flies. These plants can be placed near windows or doors, functioning as a natural barrier.
Avoiding leaving food discovered or outdoors for long periods is essential, especially during warmer days, when flies become more active.
According to the aluminum trick does not completely replace other methods, but it can be an effective, simple and economic contribution to keeping the home environment free of these unwanted visitors.
