How to Keep Flies Away While Camping

Quick answer

• Pack smart: Seal food tight, use mesh screens.
• Campcraft: Cook downwind, clean up fast.
• Natural defense: Use repellent plants, essential oils.
• Gear up: Bug nets for heads and shelters.
• Water management: Keep it clean, don’t leave puddles.
• Timing is key: Avoid peak fly hours.

What to check first (do this before you drive out)

Before you even load the car, get a lay of the land. This saves a ton of hassle later.

• Land manager / legality: Who’s in charge? US Forest Service, BLM, National Park Service, state parks, or private land? Each has its own set of rules. Check their official pages or call ahead. This is where you’ll find out about any special regulations, like dispersed camping rules or specific permits.

• Access/road conditions: Is your rig ready for the road? A dusty gravel road is one thing, but a muddy track or a washed-out trail is another. Know your vehicle’s capabilities – 2WD, AWD, 4×4? What’s the ground clearance? Don’t get stuck before you even set up camp. A quick web search for recent conditions or a call to a local ranger station can be a lifesaver.

• Fire restrictions + weather + wind: This is non-negotiable. Check current fire bans. Seriously. A careless spark can ruin a lot of things. Look at the forecast – rain, heat, wind. Wind is your friend for flies, but too much can be a pain for your tent. Knowing the weather helps you pack right, too.

• Water plan + waste plan (Leave No Trace): Where’s your water source? Is it potable or do you need to treat it? Plan for carrying it and storing it. For waste, pack it in, pack it out. This includes food scraps. Leaving food out is like ringing the dinner bell for every critter, including flies.

For your waste plan, remember to pack it in and pack it out. This includes food scraps, and a good bear canister can help keep these securely stored away from flies and other critters.

• Safety (wildlife, distance to help, comms): What animals are in the area? Bears, snakes, coyotes? Know what to do. How far are you from the nearest town or ranger station? Do you have cell service? Consider a satellite messenger for remote spots. Being prepared for the unexpected means you can focus on enjoying the trip, not stressing about problems.

Step-by-step (field workflow)

Here’s how to tackle flies once you’re on the ground.

1. Scout your campsite:

• What to do: Arrive during daylight. Look for a spot that’s relatively clear of standing water and animal droppings.
• What “good” looks like: A level spot with good drainage, away from obvious insect breeding grounds.
• Common mistake: Picking the first flat spot you see without checking surroundings. This can lead to setting up near a stagnant puddle or an animal trail.

2. Set up your shelter:

• What to do: Get your tent or shelter up quickly, ensuring all zippers are closed.
• What “good” looks like: A sealed, bug-free zone to retreat to.
• Common mistake: Leaving tent doors open while setting up. Flies will make a beeline for the interior.

3. Secure your food:

• What to do: Store all food, drinks, and scented items in bear-resistant containers or hang them properly. Keep them sealed when not in use.
• What “good” looks like: Airtight containers or well-sealed bags, stowed away from your sleeping area.
• Common mistake: Leaving food wrappers or open snacks out on the picnic table. This is an open invitation.

To secure your food, store all food, drinks, and scented items in bear-resistant containers or hang them properly. A reliable bear canister is excellent for keeping everything sealed when not in use.

4. Manage cooking odors:

• What to do: Cook downwind from your main camp area. Clean up cooking gear immediately after use.
• What “good” looks like: A designated cooking area a reasonable distance away, with all dishes washed and put away.
• Common mistake: Cooking right next to your tent and leaving dirty dishes sitting out.

5. Implement water management:

• What to do: Dispose of greywater (from washing dishes/hands) away from water sources and your camp. Fill any holes or depressions that might collect water.
• What “good” looks like: Greywater dispersed widely and soaked into the ground, no standing water around camp.
• Common mistake: Dumping dishwater directly into a stream or leaving a small pool of water near your tent.

6. Use natural repellents (optional):

• What to do: If you brought them, use essential oils like citronella, eucalyptus, or peppermint. You can also plant aromatic herbs around your camp if allowed.
• What “good” looks like: A pleasant, subtle scent that seems to deter insects.
• Common mistake: Using too much concentrated oil directly on skin without diluting, or relying solely on this without other measures.

7. Wear protective clothing:

• What to do: Use long sleeves, pants, and consider a head net if flies are particularly bad.
• What “good” looks like: Minimal exposed skin, especially during peak fly activity.
• Common mistake: Wearing shorts and t-shirts when flies are swarming, hoping for the best.

8. Maintain camp cleanliness:

• What to do: Regularly sweep out your tent, clean up spills, and manage trash properly.
• What “good” looks like: A tidy camp free of food crumbs and sticky residues.
• Common mistake: Letting small messes accumulate, creating attractants.

9. Strategic movement:

• What to do: If flies become overwhelming in one area, move to a different spot, preferably with a breeze.
• What “good” looks like: Finding a more comfortable zone by changing location.
• Common mistake: Staying put and suffering through it when a better spot is just a short walk away.

10. Pack out all waste:

• What to do: Seal all trash securely and pack it out. This includes food scraps, wrappers, and anything else.
• What “good” looks like: Your campsite looking as if you were never there.
• Common mistake: Burying food scraps or leaving trash bags tied to trees. Flies will get into them.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Leaving food unsecured	Swarms of flies, spoiled food, attracting larger pests	Use bear canisters or hang food properly; seal all food items.
Cooking right next to your tent	Attracts flies to your sleeping area	Cook downwind and away from your tent; clean up immediately.
Not managing greywater properly	Creates puddles and damp areas that attract insects	Disperse greywater widely away from camp and water sources.
Leaving tent doors open	Flies get inside, making your shelter unusable	Keep zippers closed at all times; use a screen house if needed.
Ignoring wind direction	Flies will blow directly into your camp	Set up camp and cook with the wind at your back.
Not cleaning up spills immediately	Sticky residue attracts flies and other bugs	Wipe up spills instantly; keep cooking and eating surfaces clean.
Not packing out all trash	Attracts flies and other scavengers, pollutes area	Seal trash in bags and pack it out completely.
Setting up camp near stagnant water	Flies breed in standing water	Scout for a dry, well-drained campsite.
Not using head nets when necessary	Constant annoyance, can ruin your focus	Invest in a good head net for high-fly conditions.
Relying only on one method of deterrence	Ineffective against a determined swarm	Combine multiple strategies: sealing, cleaning, and repellents.

When addressing the mistake of leaving food unsecured, remember to use bear canisters or hang food properly. This ensures all food items are sealed and less attractive to flies and larger pests.

Decision rules (simple if/then)

• If flies are thick and you’re setting up camp, then pitch your tent first and seal it up because you need a safe haven before tackling other tasks.
• If you’re cooking, then position yourself downwind of your sleeping area because cooking odors are a major fly magnet.
• If you see standing water near your campsite, then try to find a new spot or fill it in because that’s a fly nursery.
• If you’re unpacking groceries, then do it in a sealed container or inside your vehicle if possible because you don’t want to advertise your food.
• If you’re hiking, then wear long sleeves and pants because it’s easier than swatting flies off your skin all day.
• If you have a screen house, then set it up for meal times because it’s a dedicated fly-free zone.
• If you’re drinking a sugary beverage, then cap it immediately after use because the residue is a fly buffet.
• If you’re finished eating, then clean your dishes right away because leftover food is a prime attractant.
• If you’re in bear country, then any food security measure you take for bears also helps deter flies.
• If the wind picks up, then embrace it – it’s your best natural fly repellent.
• If you’re using essential oils, then test a small area of skin first because some can cause irritation.
• If you’re planning a trip in a known fly-heavy season, then pack extra netting and consider timing your activities for cooler parts of the day.
