Blackflies in a Northern June
Blackflies can turn a beautiful June ride in northern New Hampshire into a miserable one, especially when you stop on a shaded trail or pull over beside a wet, breezy-free clearing. This guide explains when and where they tend to be worst, how to protect yourself without overheating, and how to plan an ATV or UTV ride around the bugs and changing trail conditions.
Why blackflies can be so bad in northern New Hampshire in June
How weather and habitat affect blackfly activity
Blackflies thrive around moving water, so northern New Hampshire’s rivers, streams, and damp wooded areas can make June rides feel especially buggy. Their numbers and activity vary from year to year. A stretch of warm, damp weather can bring a very different experience from a cool, dry week, and conditions may change over a short distance.
The bugs are often most frustrating when the air is calm and you’re stopped. A machine moving along a trail creates airflow, but that relief disappears when you pull over to check a map, help a riding partner, or take a photo. Shady trail edges and low, wet areas can be particularly uncomfortable, while an exposed spot with a breeze may feel much easier.
That’s why two riders can describe the same weekend in completely different ways. One may have spent most of the day moving along open trails, while the other stopped often in sheltered places. If blackflies are active, the timing and location of breaks can matter almost as much as the route itself.
What riders may notice during a June ride
Blackflies are small, so they can be hard to spot before they start bothering you. They may gather around exposed skin, hairlines, ears, and the backs of hands. A helmet and riding clothes provide useful coverage, but gaps at the collar, cuffs, or gloves can leave uncomfortable patches of skin exposed.
The problem is not limited to the trail. Bugs may find you while you’re unloading machines, checking tire pressure, fastening helmets, or standing around at a staging area. It’s easy to remember bug protection for the ride and forget how long you’ll be outside before the machines are moving.
June is also a month when trail conditions can shift as spring gives way to summer. A trail that looks appealing on a map may be muddy or temporarily closed, and a route that is open may have wet, sheltered sections where bugs are more noticeable. Check local information before setting out, and review New Hampshire Trail Status Before You Ride as part of your planning.
How to protect yourself without making the ride miserable
Choose coverage that works with riding gear
Long sleeves, long pants, gloves, and socks that cover the gap between boots and pants can reduce the amount of exposed skin. Lightweight layers are usually easier to tolerate than heavy clothing when the day warms up. Choose gear that lets you move freely and won’t interfere with safe control of the machine.
Pay attention to the places clothing tends to shift. A shirt can ride up under a jacket, gloves can leave a strip of wrist exposed, and a helmet strap may leave skin uncovered around the neck. Before you ride, do a quick check while sitting in your normal riding position. That can reveal gaps you might not notice while standing.
Bug repellent may also help, but use it according to its label and avoid applying it where it could damage equipment or get into your eyes. If you use sunscreen as well, follow the product directions for applying both. Don’t assume that one application will last through a long day of sweating, wiping your face, or taking gear on and off.
Make stops shorter and more deliberate
When blackflies are active, long breaks in a sheltered spot can wear down even a well-prepared group. Plan fuel, food, and rest stops before the ride so you’re not standing around trying to decide what to do next. If you need to stop, look for a more open area with airflow rather than gathering beside a damp, shaded trail edge.
For example, a group riding near Pittsburg might pause to consult the route at a breezy, open spot, then move on before anyone gets chilled or frustrated. Another group may stop beside a stream in the woods because it looks like a peaceful place to take a break, only to find that the bugs quickly make it uncomfortable. The more exposed spot may be the better choice, even if it is less picturesque.
Keep essential items easy to reach. If repellent, a small first-aid kit, or a spare pair of gloves is buried under luggage, you may put off using it until everyone is already irritated. A simple pre-ride routine—gear check, route check, and bug-protection check—can make the first hour less chaotic.
| Riding situation | Why it can be uncomfortable | A practical adjustment |
|---|---|---|
| Stopped on a shaded trail | Calm air gives bugs a chance to gather | Keep the stop brief or move to a more open area |
| Unloading at a staging area | You may be outside before your gear is fully on | Put on protective layers before unloading |
| Taking a long lunch break | Exposed skin and inactivity can make bugs more noticeable | Choose a breezy spot and keep extra coverage handy |
| Riding through wet, wooded sections | Damp areas may feel more buggy | Stay covered and plan to keep moving where appropriate |
| Checking a route on your phone | Looking down can leave your face and neck exposed | Pull over safely, choose an open spot, and check quickly |
Plan a northern ride around June conditions
Check trail access and surface conditions first
Don’t let a map line stand in for an open, rideable trail. Seasonal access, local closures, wet conditions, and trail work can all affect a route. A path that appears connected may cross land or a corridor that is not open to OHRV use at that time. Check current information from the relevant club or land manager before you trailer north.
This matters especially in spring and early summer, when a trail can be too wet for riding even if it appears on a map. Avoid riding around a closure or choosing an unmarked detour. Those choices can damage the trail, create problems for other riders, and jeopardize landowner relationships that help keep riding areas available. For more on the seasonal side of planning, see New Hampshire’s Mud Season Ban and When New Hampshire OHRV Trails Open Each Spring.
Digital mapping can help you prepare a route and understand how trails connect, but it should be used as a planning aid rather than proof that a trail is open. Riders who use onX Offroad can review mapped routes before leaving home and keep track of their planned ride, while still checking local trail status separately. Download or save useful information before entering areas where cell service may be unreliable.
Build a flexible route and an easy exit plan
A good June ride does not need to be the longest possible ride. Consider a route with straightforward places to turn back or shorten the day if the bugs, weather, or trail surface make the group uncomfortable. Before leaving, agree on where you’ll regroup if riders get separated and what you’ll do if a machine has a problem.
Northern New Hampshire riding areas can feel remote, and mobile coverage is not dependable everywhere. Keep your route information accessible offline, tell someone where you plan to ride, and carry basic supplies suited to the length of your trip. onX Offroad may help you review a planned route, but don’t rely on any mapping app as your only way to navigate or communicate.
If your plan includes club trails, make sure your machine and registration meet New Hampshire requirements. Riders coming from another state should not assume their home-state registration automatically provides access here. Review Riding New Hampshire With an Out-of-State Machine and [New Hampshire Rules for a Visiting Rider] before setting out.
Keep the ride comfortable, safe, and considerate
Take care of yourself and your riding group
Bug frustration can turn into fatigue and poor decisions, particularly when people are hot, itchy, or eager to get moving again. Make room for breaks when someone needs one, but choose the stop carefully. Drink water, check that everyone is comfortable, and avoid rushing through safety steps just to escape the bugs.
For a family or mixed-experience group, discuss the plan before the ride begins. A newer rider may need more frequent stops, while a child may be less comfortable with bugs or changing weather. Make sure everyone has suitable protective gear and understands how the group will communicate if it spreads out. For age-related riding and supervision guidance, see New Hampshire’s Age and Supervision Rules.
If someone is having a serious reaction to a bite or feels unwell, stop the ride and respond appropriately rather than pushing on. Carry a phone if you have one, but remember that signal can be limited in remote areas. A route plan and a group check-in process are useful precisely because not every problem can be handled with a quick call.
Respect trail closures and the people who maintain access
A June ride is a privilege that depends on trails being cared for and access being respected. Stay on marked routes, follow posted signs, and don’t assume that a closed gate is temporary or that a nearby woods road is an acceptable detour. Wet ground is especially vulnerable to damage from tires, and a single muddy bypass can widen into a lasting problem.
The clubs and local volunteers who help maintain trails also share important information about changing access. Checking New Hampshire’s Club Trail Network and Clubs That Post Trail Conditions Every Day can help you prepare, but confirm details for the specific area you intend to ride. If conditions change while you’re out, turn around rather than forcing a route.
Finally, set expectations with your group. June may bring long daylight and beautiful scenery, but it can also mean bugs, wet stretches, and changing access. Bring the right layers, plan flexible mileage, and treat the trail as something to protect. With those basics in place, blackflies are more likely to be an annoyance you planned for than the thing everyone remembers about the ride.
