Do-it-yourself low-waste Insect Repellent

Bug sprays come with a host of problems and questions — 1) the chemicals used and the proven dangers of these chemicals, and 2) the packaging being the chief concerns for most people. But on the flip side, you can’t very well just let the mosquitoes dig in, leaving you itchy, red and perhaps even with a communicable disease as a result! Hence, options like this do-it-yourself insect repellent recipe.

The ideal balance is to use a repellent that works for you. Results vary from person to person for each formulation, as our unique body chemistry affect how attractive we are to mosquitoes and how certain bug spray ingredients work. Ideally one that has as few harmful chemicals as possible and can be carried in a refillable container so you can avoid sending a bottle to the recycling plant (or landfill).

Thankfully, it’s not too hard to tick all these boxes, especially after a little bit of experimenting. Of course, there will be times when the hard-hitters (ie. chemical sprays in canisters) are needed. You can limit the use of these sprays by using them only when truly needed. Relying on gentler options (as well as clothing coverage, and shelter) the rest of the time.

How to Make this DIY Insect Repellent

When it comes to making an insect repellent for your own personal use, you will likely have the most luck with essential oils that have been shown to be disliked by mosquitoes.
Please note: very few essential oils have been clinically tested to repel mosquitoes. All essential oils should be safely diluted before applying to your skin.

Materials Needed:

A simple mix of distilled water and essential oils will work just fine, but the optional ingredients could improve your spray. The emulsifier will keep your essential oils dispersed in the liquid — without it, you’ll simply need to shake your bottle well before each use. Meanwhile, witch hazel has anti-inflammatory properties and so if you do get mosquito bites, when you reapply your bug spray, the witch hazel can actually calm the itch.

Our favourite blend is equal parts water and witch hazel, with emulsifier and essential oils.

Directions for this Do-it-yourself Insect Repellent:

Start with your clean, dry spray bottle.

Count your drops of essential oils into the bottle. You will use up to 72 drops in total in a 125 mL bottle or up to 144 drops in total in a 250 mL bottle, if the spray will only be used on people over the age of 12. If you’ll be using the spray on children or the elderly, or anyone who is pregnant or breastfeeding, we recommend you play it on the safe side and stick to 24 drops in the smaller bottle or 48 in the larger bottle. For more details on safe dilution of essential oils, you can check the dilution guide on the Apothecary in Inglewood website.

Once you have added your oils, add roughly the same amount of emulsifier (it’s fine to eyeball this, and you can use a little more emulsifier with no negative effects). Swirl the bottle to blend the oils with the emulsifier.

Finally, add your water and/or witch hazel in roughly equal parts (or any ratio you like), up to the shoulder of the bottle — don’t fill all the way to the top as the tube on the mister lid will cause the level to rise a bit. Screw the cap onto the bottle and shake gently to finish mixing. If you have used emulsifier, your spray is ready to use. If not, shake well before each use.

OPTIONAL ADDITION: For extra protection, you can consider adding neem oil (which is not an essential oil) to your spray. You don’t need to include this in your essential oil calculations, but do keep it to no more than 10% of the total solution — so in a 125 mL bottle, add 12.5 mL or less. Keep in mind that it doesn’t smell good! But as a known repellent, neem oil can definitely mean fewer bites.

Oils That Bugs Hate

It is important to remember, essential oils may not be as effective as repellents containing DEET. However, there are plenty of times that they will be sufficient for your needs. Below you will find a list of essential oils known to repel insects. Try one or any number of the oils listed, in any combination you like. You can use many oils specifically known to repel mosquitoes. You may consider lavender, neem and geranium oils as these are also known to repel ticks.
