Is DEET safe for use on children and pregnant women for insect bite prevention?

Insect repellent products containing DEET are considered a safe and effective option for use by children and pregnant women, provided they are used according to the directions on the product label [4]. Regulatory agencies do not recommend additional special precautions for these two groups, meaning that general instructions for use are sufficient to ensure protection and minimize any potential risks. DEET remains one of the most reliable and well-studied ingredients for preventing bites that may transmit diseases.

DEET Safety for Children and Infants

DEET does not have age restrictions when used in insect repellent products, making it suitable for children of all ages [4]. To ensure maximum safety during application, adults should handle the process themselves. It is always recommended that an adult apply the repellent to their own palms first, then gently wipe it onto the child's exposed skin. It is essential to avoid applying the product directly to a child's hands to prevent accidental ingestion or contact with the eyes [4]. Care should also be taken not to apply the repellent to areas with cuts or skin irritation. Upon returning indoors, it is best to wash the child's skin and any clothing that came into contact with the substance using soap and water.

Using DEET During Pregnancy and Breastfeeding

There are no additional medical warnings prohibiting pregnant or breastfeeding women from using products containing DEET when following manufacturer instructions [4]. Protection against insect bites remains essential to avoid vector-borne diseases; therefore, the responsible use of these repellents is considered a prudent preventive measure. It is advised to use only the amount necessary to cover exposed skin and to avoid overuse.

Rules for Optimal Use and Precautions

To achieve the maximum benefit from DEET while ensuring safety, the following rules should be followed:

• Order of Application: If sunscreen needs to be used alongside insect repellent, apply the sunscreen first, followed by the repellent [4].
• Avoid Overuse: There is no need to saturate skin or clothing with the substance; a thin layer is sufficient to provide the required protection.
• Concentration and Effectiveness: Higher concentrations often provide protection for a longer duration, so choose the appropriate concentration based on the time you will spend outdoors [4].
• Alternative Prevention: In addition to repellents, it is advised to wear clothing that covers the legs and arms, and to use mosquito netting for strollers when necessary to reduce the need for direct chemical application [4].

In rare cases, skin reactions such as redness or itching may occur due to the use of any insect repellent. If this happens, the area should be washed thoroughly with soap and water, and use should be discontinued. If a person experiences more severe symptoms such as facial swelling, difficulty breathing, or a widespread rash, immediate medical attention must be sought [2].
