Making Insect Repellent: Protecting Ourselves from Nature's Silent Threat
Insect repellent
Imagine a world where you are suddenly thrust into the wild with nothing but your wits and whatever you can salvage. The "Rebuilding from Zero" blog aims to consider exactly that scenario—what skills are essential if we had to rebuild civilization from scratch? One thing that might not be top of mind, but absolutely should be, is how to stay safe from insects. Insects are not just a nuisance; they can be deadly. From malaria to dengue fever, insects are one of the greatest uncontrollable transmitters of disease. So, staying alive and relatively comfortable means finding a way to keep them at bay. Fortunately, making insect repellent from readily available materials is a skill worth having, and it's possible with just a little know-how.
Insects are vectors for many dangerous diseases, and being able to protect yourself from their bites can be the difference between life and death. For example, mosquitoes alone are responsible for millions of deaths worldwide each year due to the spread of malaria, dengue fever, and Zika virus. In a world where modern medicine may no longer be easily accessible, prevention becomes the first line of defense. With just a bit of ingenuity and resourcefulness, you can make effective insect repellents using ingredients you might be able to scavenge or find in nature. Let’s dive into a few methods that could be invaluable in a post-collapse scenario.
Here, we’ll explore several effective methods for making insect repellent, using ingredients you can either salvage or find naturally in the environment.
Method 1: Smoky Herb Bundles
One of the simplest ways to repel insects, especially mosquitoes, is with smoke. If you find yourself near a fire, adding specific plants to the flame can make the smoke more effective. Plants like sage, rosemary, or thyme are natural insect repellents. Simply bundle these herbs together and throw them into your fire or let them smolder slowly.
The aromatic compounds released by burning these herbs help to deter mosquitoes and other insects, creating a protective zone around your camp. This method is ideal if you have a campfire going and want to make the area around you less attractive to bugs. Smoke disperses quickly and covers a wide area, making it one of the simplest and most effective tools for immediate protection. Plus, it’s easy to adjust based on your needs—add more herbs for a stronger effect or let it smolder to maintain a steady level of protection throughout the night.
Method 2: DIY Oil-Based Repellent
If you have access to any form of oil—olive oil, coconut oil, or even some salvaged cooking oil—you can make a simple insect repellent. Essential oils like eucalyptus, lavender, or tea tree are best for mixing with your base oil, but if you don’t have those, you can use the herbs themselves.
Ingredients: 1 part dried herb (like lavender or thyme), 10 parts oil
Instructions: Heat the oil gently and add the dried herbs. Let it simmer for about 30 minutes, then strain out the herbs. Once cooled, rub the oil mixture onto your skin. The strong scents of the herbs are offensive to many insects, particularly mosquitoes.
The benefit of an oil-based repellent is that it provides lasting coverage on the skin, making it effective for several hours. Coconut oil, in particular, has natural antibacterial and antifungal properties, adding an extra layer of protection for your skin in rough environments. This type of repellent is also highly versatile—you can use different herbs depending on what’s available, and the repellent can be stored for future use if kept in a cool, dark place.
Method 3: Vinegar and Herb Solution
If oil isn’t available, vinegar is a great substitute. It’s commonly found and easy to salvage, plus it’s an excellent medium for extracting the insect-repelling properties of herbs.
Ingredients: White vinegar or apple cider vinegar, and insect-repelling herbs such as mint, lavender, or lemongrass.
Instructions: Fill a jar with the herbs and then cover with vinegar. Let the mixture steep for 1-2 weeks if possible. Strain out the herbs, and you’ve got a repellent that can be applied directly to skin or clothing. The smell might be intense, but it’s a small price to pay to keep insects away.
The acidic nature of vinegar makes it an effective solvent for drawing out the essential oils of the herbs, and the strong odor is highly unpleasant to many insects. While the smell may be a bit overwhelming initially, it fades relatively quickly for humans, though it continues to repel bugs. This type of repellent can also be used to spray around sleeping areas or on tents to create a wider barrier of protection.
Method 4: Mud Coating
If you’re truly in a bind, consider using mud as a temporary insect repellent. While it may seem rudimentary, applying a layer of mud to exposed skin can create a physical barrier that mosquitoes and other insects can’t penetrate easily. It’s certainly not the most comfortable or sophisticated solution, but it can be a lifesaver when other options aren’t available.
Mud works by creating an impenetrable barrier that prevents insects from reaching your skin. It also helps to cool your body in hot environments, which can be an added benefit when working or traveling under the sun. Although not long-lasting, reapplying mud is straightforward, and it can be especially useful when dealing with swarming insects during peak biting hours.
Why These Methods Matter
In a situation where civilization has collapsed, where the comforts of DEET sprays and bug zappers are relics of a lost era, knowing how to craft your own insect repellent could be crucial to survival. Mosquitoes, in particular, are responsible for spreading deadly diseases like malaria, dengue fever, and Zika virus. These diseases, often uncontrollable without medical intervention, can decimate populations and make survival infinitely more challenging.
Mosquitoes are most active during dawn and dusk, which makes those times particularly dangerous. Learning how to protect yourself using materials you can find or scavenge is an essential survival skill. Even in less extreme scenarios, such as after a natural disaster, modern supplies can run out quickly, and access to conventional insect repellents may be limited. Knowing how to make effective repellents from basic, natural materials could help you and your community stay safe and significantly reduce the risk of infection from insect-borne diseases.
It’s also worth noting that while these methods may not provide the 100% protection of modern repellents, they can significantly reduce bites and make your environment much more comfortable. Reducing the number of bites you receive can lower your risk of contracting diseases and improve your overall quality of life, especially when medical assistance is scarce.
Final Thoughts
The art of making insect repellent is more than just a survival skill—it’s a testament to human ingenuity and adaptability. Whether you’re facing a collapse of society or just trying to stay safe in an environment lacking in modern comforts, these methods will help you protect yourself from one of nature’s smallest but most dangerous threats.
The skills we discuss in "Rebuilding from Zero" aren’t just theoretical—they’re practical tools for anyone looking to be more self-sufficient. With a bit of resourcefulness and the right knowledge, even something as basic as staying bug-free can be within reach. These skills can be applied in a wide range of situations, from camping trips in remote areas to responding to emergencies when supplies are limited. By mastering these techniques, you not only increase your chances of survival but also enhance your confidence and ability to thrive in difficult circumstances.
