While I’ll bet you will not find a single mosquito buzzing around today here in the Northeast, they will be back and if you trek to some place warm in the next few months your odds of coming in contact with them increase greatly.
What’s out there Malaria, Dengue Fever and now Zika Virus.
We do have mosquito borne
encephalitis and tick borne
lyme disease, etc. Warm winters/Wet Springs and a reduction in some species of bats, birds and amphibians have created no shortage of flying and crawling insects in this part of the country and I’m sure elsewhere as well.
So I suppose the first thing we can do is to never go outside. But that is not practical.
If you are going to be in wooded or tall grass areas for periods of time one passive way to cut exposure is to wear long sleeve shirts and long pants. Many people will treat the cuffs of their shirts and pants with a
deet based repellent so that the insects will not crawl up their sleeves. Going one step further some people wash there clothing in
Permethrin which is a poison and when the insects get on it they die. Permethrin is supposed to be safe when dry for humans but then again off shore oil drilling and bpa bottles were supposed to be safe too.
Insect repellents come in all flavors I would suggest using whatever works for you. Personally I use either a high DEET repellent or
Bullfrog which is a blend of insect repellent and sun screen. I like the fact that I only have to carry one bottle. It stinks to be using bug repellent in the winter but what can you do. I also try to not use insect repellent on my face or forehead where the sweat is going to run down into my mouth.
Insect Jackets, Pants and Headnets are another way to keep bugs at bay. I would recommend them for people who are not exerting at high level of exertion. Another important point is that insect garments should be worn loose enough so that the insects can not light on the netting and bight through.

When sleeping in the outdoors or places with no window screens you want to either place
insect netting over the window opening or hang a net over you that will keep the bugs again from lighting and biting through. One of the biggest problems is figuring out what types of bugs are in the area and how do you hang the net in the space you have.
Noseeum bugs will go through window screens and standard mosquito netting. Although the WHO (World Health Organizations) standard is ~ 120 holes per square inch some smaller mosquitoes and black flies will go through it as well. So find out what is native to the area.
Insect nets can be self standing, hang from one point or four points. My personal favorite is a single point net or
bed net canopy which is easier to use in many situations than other nets.
There are also insect nets that are treated with permethrin to kill bugs on contact. In any case I would carry 50′ feet of cord so that you can tie into the walls of any domicle.
