Ticks in Fall

Now that summer is over you can stop worrying about ticks, right? Think again.

While summer in New England is a prime time to spot deer ticks (the chief culprits of Lyme disease—a potentially serious bacterial infection), many don’t realize that they can still pose a serious threat in the fall. This is especially true for those who love a good old-fashioned roll in a leaf pile.

Keep these pesky (and dangerous) little critters from ruining your autumn adventures by following these tips:

  • Know Where They Hide Contrary to popular belief, ticks do not jump or fall from trees; in fact, they’re blind and find their hosts by crawling to the top of low-lying vegetation, such as grass and shrubs, where they wait for passersby to latch onto. And, since tick bites are usually painless, most people don’t even know when they’ve been bitten.
  • Keep a Tidy Yard At home, keep your lawn mowed short and your yard clear of leaves and other brushy debris. If your property abuts a wooded area, adding a three-foot-wide wood chip or gravel border around the edge of your yard can help prevent tick migration.
  • Watch Where You Walk Stick to wider trails and avoid overgrown pathways in their preferred habitat: wooded or bushy areas where the ground is covered in high grass or leaf litter.
  • Dress Right Don light-colored socks, pants, and a long-sleeved shirt and tuck in everything (pants into socks, shirt into pants). While this look isn’t likely to win a fashion awards, it will allow you to spot ticks, which can be as small as a poppy seed.
  • Bring On the Bug Juice To help repel ticks and other creepy crawlers, like chiggers, use a DEET-based product on areas of exposed skin. (Just remember to follow the label instructions when applying insect repellent!)
  • Perform “Tick Checks” Upon heading indoors, perform a full-body “tick check,” taking special care to inspect the areas between your toes and the backs of your knees, as well as your groin, armpits, neck, hairline, and ears. Remember to check your children, pets, and gear, too!

Been Bitten?

If you discover an embedded tick, use fine-tipped tweezers to grasp the tick as close to your skin’s surface as possible and pull straight out with steady, even pressure. If you wish to have it tested for Lyme, immediately place the tick in a sealable plastic bag. Cleanse the bite area with rubbing alcohol and wash your hands with soap and water. Make a note of the date as well as the location on your body where the tick was discovered and call your doctor to determine next steps.

How to Buy Binoculars

You’re ready to take the plunge and buy a pair of binoculars and you might think to yourself, “How complicated can it be?” That is, until you start to notice the dizzying array of available brands, features, and prices. Before you get overwhelmed, check out this basic primer on what you need to know before buy (and learn how to save 15 percent!).

Magnification
Binoculars are marked with a set of two numbers that indicate their power of magnification and the diameter of their objective lenses (we’ll get to this in a minute). If a pair of binoculars is marked “8×42,” the first number indicates that they will magnify the object you’re looking at eight times larger than its actual size.

A common mistake made by first-time buyers is thinking that bigger is better. While it’s true that greater magnification provides a larger image, it can also make it difficult to maintain a steady view of what you’re looking at. The average birder uses a magnification power of 8 to 10, which affords a good amount of detail without the shakiness experienced at higher magnification levels.

Brightness
If magnification determines how much detail you see, the diameter of the objective (aka front) lenses determines how well you see it. Think of it like this: the wider the objective lenses, the greater the light-gathering ability, which ultimately translates to greater detail and clarity.

You can identify the size of the objective lenses on a pair of binoculars by looking at the second number in our 8×42 example, which refers to the diameter of each objective lens in millimeters.

Field of View (FOV)
This measurement tells you how wide the area is that you can see through your binoculars. Of course, the more you can see, the easier it is to follow a fast flying bird, or catch movement off to the side.

Field of view is measured either in degrees or in feet per thousand yards and, like magnification and brightness, is usually marked right on the binoculars.

Eye Relief
For those who wear eyeglasses, this may be one of the most important features to consider when selecting binoculars.

Eye relief refers to the distance (in millimeters) between your eyes and the part of the binoculars you look through at which you can still maintain a full field of view. Since eyeglasses necessitate a space between the eyes of the user and the binoculars, those with glasses will want to look binoculars with at least 15mm of eye relief. If it’s not on the box, ask the salesperson.

Quality
Not all lenses are equal. High-quality lenses are made from superior glass and prisms and have better optical coatings that maximize the amount light directed to your eyes, making images appear brighter and clearer. The quality of the coating on binocular lenses is actually one of the things that distinguish top-of-the line optics brands from others.

Comfort
Above all, your binoculars should “feel right” to you. Take a minute to focus on objects near and far. How easily are you able to make adjustments? Can you hold them up to your eyes for a minute or two without feeling overly fatigued? Can you carry them with ease? Binoculars are an investment that can be enjoyed for a lifetime, so take the time to choose what’s right for you!
