First off, sandflies in New Zealand are not actually sandflies. Rather, these pesky little bugs are female black flies more thirsty for blood than a dehydrated vampire. If you plan on going outside, or opening a window, in the Westland region (i.e. the whole West Coast) of New Zealand’s South Island, you will encounter sandflies.
True, they are more prevalent in the bush (read: woods) than in the cities but contact with these annoying pests is inevitable.
Facts About Sandflies
- Sandflies Travel in Swarms: You will rarely be attacked by one sandfly as they seem to hunt in packs. If you see one, the rest of its friends are busy stealing your blood.
- Sandflies Are Not Fast: If you are walking in the bush or kayaking on a river, the sandflies will leave you alone as they cannot keep up. Problematically, when you stop for that well earned water break a whole cloud of sandflies will quickly find you and start feasting. On a positive note, you won’t have a problem killing them as they are too slow to avoid a solid slap. Keep in mind though that in the time it takes to kill one, three more will leech onto your foot.
- The Wind and the Rain: Sandflies cannot tolerate either wind or rain. So, if you can brave the elements, you will avoid the majority of these swarming little blood suckers.
Develop a “Sandfly Strategy” that works for you. Every person is affected by sandflies in a different manner and how you protect yourself from them will likely be determined by how much they like you.
How to repel and avoid being bitten by sandflies
- Buy Local Repellent: When you get to the Westland area, every tour operator and outdoor adventure store will have locally made sandfly repellent at the checkout counter. Buy it. The repellent from other places in the world doesn't work as effectively as the local formula. The locals had 100 years to figure out a way to keep sandflies from stealing liters of their blood so you can trust them to concoct an effective solution. If you do not like DEET, good luck. DEET is the main active ingredient and is far more effective than the natural products. In fact, if you don't like DEET, just avoid the South Island's west coast all together.
- Cover Up: It does not get very hot and, if you are hiking, chances are you will be under the canopy. Long pants and sleeves provide effective protection from swarming sandflies.
- Apply Repellent BEFORE You Get Out of the Car: Many people park at a trail head, slowly get out of the car, and begin applying sandfly repellent. You are already too late! The sandflies are trapped in your car and they will feast on you when you return. While the sandflies are colonizing your car, their friends are latching onto your major arteries as you frantically attempt to apply repellent and kill sandflies simultaneously. To be kind, this is usually ineffective and is a poor start to your hike. Put the repellent on before you get out of the car to avoid this cyclical problem.
- Drive Away: If you are sleeping in your campervan or car you will often park for the night in high sandfly areas. Close your van up as soon as you finish cooking to keep the majority of the sandflies outside. In the morning, try to drive away from the campsite to a location not surrounded by the bush. This should prevent the sandflies from swarming into your van while you re-arrange your belongings for the days drive. Otherwise, the sandflies will feast on your feet as you scramble to get your car onto the road. Getting eaten by sandflies while operating a vehicle leads to dangerous driving.
- Don’t Complain About Sandflies: Complaining will not attract sandflies but it will not help you make friends either. In the Westland Region, sandflies are a way of life. If you cannot handle them go somewhere else. Your fellow travelers and the locals will have little patience for your complaints.
If you follow all of the above listed advice, you probably will still get bitten by sandflies but just not as much! When this occurs, do not scratch the bite. Scratching simply spreads the itch and extends the amount of time it takes the wound to heal. Plus, scratching leads to more scratching and that simply escalates the problem. Instead, apply hydrocortisone cream. This will cut down (but not eliminate) the itching and will also help your skin heal more quickly.
