Flies, these tenacious intruders

The presence of flies proves to be a real nuisance. As soon as a meal is being prepared, these pesky insects appear with disconcerting persistence. The fear of consuming food contaminated by their droppings, potentially harboring bacteria, is legitimate. Flies are opportunists, attracted by the slightest delicious scent, and quickly invade your space. To regain tranquility, it is necessary to devise effective and natural solutions.

Preparing your homemade fly trap: necessary ingredients

Making a homemade fly trap requires little equipment and budget. A container, such as a glass or a plastic bottle, serves as the base. An attractant like cider vinegar or baker’s yeast is an excellent choice. These substances emit savory odors for flies, ensuring their presence. Add a few drops of dish soap, which alters the surface of the water, allowing the flies to be trapped. This method is both simple and effective while being eco-friendly.

Making a classic vinegar trap

The vinegar trap proves convincing and easy to execute. Fill a bowl with a bottom of cider vinegar and add a few drops of dish soap. The flies, attracted by the sour smell, dive into the mixture and get trapped. For optimal effect, cover the top of the bowl with plastic wrap and poke a few small holes, allowing the insects to enter while preventing them from escaping. Hanging this trap near at-risk areas increases its effectiveness.

The yeast trap: a formidable method

Baker’s yeast, well-known in the kitchen, is an ally for trapping. In a plastic bottle, adjust a cardboard funnel. Add water, sugar, and a packet of yeast. This mixture will ferment, producing an irresistible aroma for flies. The design of this trap combines cleverness and creativity while involving children in the process. This fun activity allows the youngest to be introduced to the mysteries of science while solving a household problem.

Complementary natural tips

Taking care to apply preventive methods is essential. Protecting fruits, a favorite source for flies, becomes crucial. A cover helps preserve the integrity of your goods. Avoid cluttered sinks and thoroughly clean surfaces. Certain plants, like lavender or mint, prove to be formidable allies in repelling pests. Essential oils diffused into the atmosphere also act as an effective olfactory barrier, discouraging flies from venturing into your home.
