Snake Bite First Aid

Pit Viper
The pit viper has “pits,” on their heads. These organs help the snake locate prey and adjust the amount of venom used according to the size of their prey.
The glands, or venom sacks are connected to the fangs, which act like hollow hypodermic needles. These fangs are voluntarily controlled by the snake. They can raise either one or both fangs, or neither.
When fangs break off, there is usually another fang below, or there may be one next to it.
Therefore, snakebites can present as one puncture wound, two, three or even four.
The pit viper can strike about 50% of its body length, and has been recorded to strike at about 7 feet per second. The forked tongue is equivalent to our nose. The snake senses chemicals in the air with their tongue, aiding in the location of prey.
Their pupils are elliptical, and all pit vipers in the United States have elliptical pupils, as opposed to non-venomous snakes which have round pupils. The age of a rattlesnake cannot be determined by the number of rattles. Rattles frequently break off, and therefore is an unreliable method to determine age.

Lean-to shelter in the wilderness

A shelter can protect you from the sun, insects, wind, rain, snow, hot or cold temperatures, and enemy observation. It can give you a feeling of well-being. It can help you maintain your will to survive. In some areas, your need for shelter may take precedence over your need for food and possibly even your need for water. Assess the situation. How long do you think you will need your lean-to? How urgently do you need to make a lean-to? Theses things will let you know how strong to make your shelter, or how much time you need to spend on it.  Scan the ground, find some sticks, about the size of two thumbs width. If you can't find the right size, make due with what you can find. If you have a pocket knife on hand, cut them off of short trees, preferably without leaves, branches are fine. You will need long limbs. Look around you. Find a few large trees, if you can find a particularly large one, that’s very good, if not, find a few that are very close together, perhaps a foot apart. Check the warning at the bottom of the page.  How to build a lean-to

Black Widow Spider

Biting insects can hide in your foot wear. If you do get an insect bite it usually can be treated on the spot. Mosquitoes, gnats and flees bites will not show up immediately so you need to watch the area for any signs of infection. Tick bites you need to cut off the oxygen to the head of the tick to remove the tick safely.

When you have been bitten by an insect you should stop all strenuous activity. Watch for hives and bee's nests around hollow rotted logs and low lying tree limbs too.
Black Flies have a terrible and nasty insect bite that can itch and sting, black flies will also swarm over you, they will crawl and wiggle to get under clothing to get your skin and bite Unfortunately Deet doesn't work as very good to repel blackflies like it does for mosquitoes  Insect bites spider bites
