Mosquitoes are a problem that returns every year as the weather grows warmer. Spring already gives these persistent insects their first opportunity to strike. As the days lengthen and temperatures rise, mosquito populations grow — and so does the number of painful, itchy bites. But it does not have to be this way. Today, there are more effective methods of dealing with mosquitoes than ever before, so they no longer need to ruin your time at home or in the garden.
How to Protect Your Home from Mosquitoes
Closing windows and turning off lights might seem like a logical first step, but it is neither fully effective nor particularly comfortable — especially on hot summer nights when an open window is the only relief. A mosquito net on windows helps, but what about doorways and other entry points?
One of the most practical solutions is an electric mosquito repellent device. These compact units plug directly into a standard wall socket and work in one of two ways, depending on the model. Some emit an ultrasonic signal that is inaudible to humans but effectively deters mosquitoes. Others release a gentle, odourless vapour that creates an invisible barrier insects cannot cross. For vapour-based devices, remember to replace the refill cartridge regularly to maintain continuous protection.

Natural methods also work well indoors. Mosquitoes are sensitive to certain scents — vanilla and peppermint oil, for example, are highly effective natural deterrents. Diffusing these in your living space not only keeps mosquitoes away but also leaves your home smelling wonderful. Tea tree oil is another popular option that many people use as part of their insect defence strategy.
Keeping Mosquitoes Out of Your Garden
A garden is one of the great pleasures of warmer months, but mosquitoes can quickly turn an evening outdoors into a miserable experience. This is especially true if you have a pond or any standing water feature, which serves as an ideal breeding ground for these insects.
Fortunately, protecting your garden does not require extreme measures — no need to sit inside a screened tent or drain your pond. A simple and effective approach is to spray plants with a mixture of peppermint oil and water. Scented spirals (mosquito coils) placed around seating areas also release a fragrance that mosquitoes find unpleasant. Both methods create a natural deterrent zone that makes outdoor time far more enjoyable.
[note:Standing water — even small amounts in plant saucers or gutters — is where mosquitoes lay their eggs. Regularly emptying these can significantly reduce mosquito populations around your home.]
Personal Protection Against Mosquitoes
Sometimes protecting your home and garden is not enough. A walk in the woods, a camping trip, or simply spending time near lakes and rivers means direct exposure to mosquitoes. This is where personal insect repellents become essential.
The most widely used active ingredient in mosquito repellents is DEET (N,N-Diethyl-meta-toluamide). Rather than killing mosquitoes, DEET works by disrupting their nervous system and impairing their ability to detect carbon dioxide and other metabolic byproducts that humans naturally emit. Unable to locate their target, mosquitoes simply stay away.
DEET has a long history of use. It was originally developed by American chemists for the US military, which needed effective protection for soldiers fighting in humid tropical forests where mosquito-borne diseases posed a serious threat. First used in military operations in 1946, DEET became available to the general public in 1957 and has remained the gold standard in insect repellents ever since.
Today, DEET-based repellents are available in multiple formats — sprays for broad coverage, roll-ons for precise application, and creams for sensitive skin. The concentration of DEET varies between products, typically ranging from 9.5% for mild, everyday use to 50% for intense outdoor activity or travel to tropical regions. Our insect repellent collection includes options across this full spectrum.

Mosquito Protection for Babies and Young Children
DEET has long raised questions about safety for the youngest family members. However, the American Academy of Pediatrics has studied its effects and concluded that DEET-based products are safe for infants from two months of age, provided the concentration does not exceed 30%. Despite this reassurance, many parents prefer to limit chemical exposure for their children.
For newborns and very young babies, alternative methods are recommended. Ultrasonic plug-in devices that emit sounds imperceptible to humans are a popular chemical-free option. Natural repellents — such as vanilla, peppermint, or tea tree oil diffused in the room — also provide gentle protection. Another simple trick is to use yellow light bulbs instead of white ones, as mosquitoes are attracted to white light but largely ignore yellow wavelengths.

For families with older children who spend time outdoors, the insect and tick protection range at Medpak includes both DEET-based and electronic repellent options suitable for different ages and situations.
Choosing the Right Mosquito Repellent
With so many options available, choosing the right approach depends on your specific situation. Here is a quick guide to help you decide:
- At home (indoors) — electric plug-in repellents, mosquito nets, essential oil diffusers
- In the garden — peppermint oil sprays, mosquito coils, removing standing water
- Outdoors and travelling — DEET-based sprays (9.5–50%), roll-ons, or creams
- For babies under 2 months — ultrasonic devices, natural scents, yellow light bulbs, herb-filled windowsills
- For children over 2 months — DEET products up to 30% concentration, or natural alternatives
The variety of mosquito protection methods available today means there is a solution for every person, every space, and every situation. Whether you prefer natural approaches, electronic devices, or proven chemical repellents, the key is finding what works best for your lifestyle — so you can enjoy the warm months without the constant buzz and bite.
