DEET, a chemical compound commonly found in insect repellents since the 1950s, has been effective in warding off pesky mosquitoes.
Although its exact mechanism of action is not fully understood, scientists propose two main theories: DEET either blocks the receptors that mosquitoes use to detect humans, making it harder for them to find and bite us, or mosquitoes simply dislike the smell.
However, DEET is a potent chemical that was not initially developed with skin sensitivities in mind. Unfortunately, many individuals with sensitive skin experience irritation and an increasing number of people have reported developing allergies to DEET. If you have a DEET allergy or sensitivity, it is crucial to find an alternative insect repellent that suits your skin while still providing protection against mosquitoes.
One such alternative is picaridin, a synthetic compound that has been used as an insect repellent since the 1990s. Like DEET, picaridin repels mosquitoes rather than killing them.
However, it is considered less toxic and less likely to cause skin irritation. Picaridin is widely available in Australia and serves as a suitable substitute for those with a DEET allergy. Nonetheless, it is worth noting that most picaridin formulations contain high levels of alcohol, which can be drying and irritating, particularly for individuals with sensitive skin.
Another DEET alternative is OLE, short for Oil of Lemon Eucalyptus. OLE is derived from the leaves of the lemon eucalyptus tree and is known for its insect-repellent properties.
By masking the scents that attract mosquitoes to humans, OLE helps keep them at bay. However, most OLE-based insect repellents in Australia also contain high levels of alcohol, which can cause dryness and irritation, making them less suitable for individuals with skin sensitivities. It is important to note that OLE is not recommended for use on children under three years old.
For those who prefer natural, botanical-based insect repellents, several options are available. These repellents typically utilize essential oils such as citronella, lemongrass, rosemary, cedarwood, and lavender to repel mosquitoes. They are generally considered safe for use on the skin and provide a natural alternative to chemical-based repellents. However, it is crucial to ensure that any natural insect repellent used has been clinically proven and approved by the Australian Pesticides and Veterinary Medicines Authority (APVMA) to ensure both safety and effectiveness.
Not all natural products claiming to repel mosquitoes have undergone clinical testing. Furthermore, it is important to recognize that natural does not necessarily mean gentler on the skin.
If you have a history of skin sensitivities, it is important to carefully consider the products you choose. While citronella is an excellent active ingredient in mosquito repellents and is tolerated well by many individuals with DEET allergies, it may still be problematic for those with sensitive skin.
Other ingredients like rosemary, cedarwood, mint, and thyme may also irritate the skin. A lavender-based, hydrating cream called Good Riddance Sensitive Insect Repellent could be a great alternative specifically developed for sensitive skin and babies.
Mosquito repellent stickers or wristbands infused with citronella and essential oils claim to provide protection against mosquitoes. However, these products are unlikely to offer the same level of effectiveness as properly applied mosquito repellents.
To be effective, insect repellents should be applied to all exposed skin. Even DEET-based products will not protect you adequately if you miss a patch of skin. Relying solely on a single sticker or wristband is unlikely to provide sufficient protection, especially in areas with high mosquito activity. See here for more on DEET and repellents.
