Protecting yourself against the Aedes aegypti mosquito, a vector of diseases such as dengue, is a constant concern, especially in tropical regions.

What are the symptoms of dengue?

Dengue is a viral disease transmitted mainly by the bite of the Aedes aegypti mosquito. Symptoms can range from mild to severe and, in extreme cases, can lead to death.

Therefore, preventative measures such as the use of repellents play a crucial role in reducing the risk of infection.

What are the most effective repellents against dengue?

The National Health Surveillance Agency (Anvisa) regulates repellent products in Brazil and recognizes some active substances as effective against Aedes aegypti.

Among them, DEET (N-dimethyl-meta-toluamide or N,N-diethyl-3-methylbenzamide) and Icaridin (Hydroxyethyl isobutyl piperidine carboxylate or Picaridin) stand out.

There are also registered products containing plant extract or citronella oil as active substances.

Expert recommendations

Experts emphasize the importance of choosing repellents with active substances with proven effectiveness, such as DEET and Icaridin.

Studies carried out by renowned institutions, such as Unesp Botucatu, corroborate the superiority of these compounds in preventing Aedes aegypti bites.

How to apply dengue repellents?

Furthermore, it is important to mention that, in addition to the active substance, the concentration of the repellent also influences its effectiveness and duration.

In this sense, repellents with higher concentrations tend to offer longer-lasting protection, generally indicated on the product label.

Safe use in children

The use of repellents on children requires special attention, as not all formulations are suitable for this age group.

Products based on DEET, Icaridin and citronella oil can be used in children over 2 years old, following the guidelines for concentration and frequency of application.

Do homemade repellents work for dengue fever?

Despite the popularity of homemade natural repellent recipes, their effectiveness and safety are questionable.

Therefore, experts warn that many of these products do not have scientific proof of their effectiveness or can cause skin irritation.

Repellents for non-environmental use

In addition to personal repellents, there are products intended for use in the environment, such as spirals, liquids and tablets.

However, it is important to observe the recommendations for use to avoid health problems, especially in people with asthma or respiratory allergies.

Choosing the appropriate repellent is essential to guarantee effective protection against the dengue mosquito.

Choosing products approved by Anvisa, with recognized active substances and adequate concentrations, is the best way to protect yourself and your family against this disease.
