When an insect infestation appears at home, it is often quickly associated with a lack of cleanliness. However, although keeping all rooms clean prevents the appearance of these little creatures, many times it is enough to leave the door or window open for them to enter. In summer, high temperatures and humidity create the perfect environment for them to reproduce, so flies, mosquitoes, cockroaches, or ants become common during these months.

A very safe alternative for those at home
These ultrasonic repellents stand out as a discreet and odorless alternative. Unlike other methods, these small devices use high-frequency waves, imperceptible to us, to repel insects. They do not use chemicals, making them a very safe option for daily use.
Each pest usually requires a specific treatment. That is why these repellents have three smart modes that adapt to different types of insects. This is quite practical to avoid accumulating baits, traps, or insecticides at home.
- Green mode: mosquitoes and flies. It is the softest and quietest mode, making it ideal for bedrooms.
- Blue mode: for cockroaches and larger insects that are usually found in areas where there may be food residues, such as the kitchen.
- Red mode: designed to repel rodents, so it emits a sound more uncomfortable for them. It is the most powerful of the three levels.

Installation without complications
These repellents are designed for indoor use, whether in any room of the house or outside the domestic environment (offices, warehouses, etc.): just plug it into the power outlet to start working. Another advantage is that, thanks to its compact and minimalist design, it is barely noticeable. They only emit a dim light that often serves as a night light. “The design is quite modern and discreet, so it does not clash in any room,” says a user.
For greater effectiveness, it is recommended to leave them connected 24 hours a day. The results are noticeable progressively, helping to keep the home protected against those annoying insects. “I have been using them for a few weeks and have noticed far fewer mosquitoes at home,” adds another person who has bought this pack.
