What do you do for mosquitoes?

Hello all,

I'm just wondering what people do for mosquitoes.  I've searched in the past and found a number of suggestions.  I was hoping I might get a little more time before they became bad, but it seems that they are out in force already.

Things I have seen heard/tried:
  • Bug spray
    • I have tried Off Deep Woods and other sprays, and for where I live, it pretty much does nothing at all.
    • I have read it's fairly corrosive and to be careful around plastics, although almost all of my AP equipment is metal.  My Dobsonian for visual has some plastic materials.

  • Big fans
    • It seems to help a little, but it's another large piece of equipment to drag out into the yard.  I turn it off while shooting.

  • Bug zapper/lamp
    • It sounds like a machine gun going off here.  Seems to pull some away from me to the lamp, but again it's something else to drag outside and turn off when shooting.

  • Thermacell devices
    • I haven't tried it, but I am hesitant due to the fumes being toxic to a number of animals including birds, which nest near where I would need to set it up.

  • Baggy winter clothing and hat
    • Even if I wear jeans, if I am sitting down outside, anywhere where the material is close to the skin, I end up with bites.  I had probably 20 on my knees where the jeans were against the skin when sitting one night.
    • This seems to be the best option so far.  The only problem is it gets extremely hot, but that isn't too bad compared to the bites.


This week in the time it took me to do my polar alignment and focus (everything else can be done inside), I ended up with somewhere between 100-200 bites.  I wish it was hyperbole, but it's not.  I also have a mild allergic reaction to each bite with them swelling up and causing a 1-2 cm diameter welt that is raised 3-4 mm off the skin.  Last year when I got my first scope, a dobsonian, and was doing visual observations, my entire back was swollen, which prompted me to look at options.

I have seriously considered getting something like a cheap bee suit that I could wear during polar alignment.  Once it gets later into the night they aren't as bad.

Any suggestions or advice is welcome.

For reference I live in southern Louisiana in the United States in what some would consider a swamp or marsh, and I love it here.  It just causes some issues with AP.

I live in Wisconsin and mosquitos can be very troublesome in summer. Deep Woods has worked for me. I use the highest strength version and keep a can in my car at all times. I spray it on and rub to make sure it covers every bit of exposed skin including ears, neck, face, etc.

Do you use the mini pump that is 98% DEET?  I have tried the regular Sportsmen version that is 30%.  Everything is either 25% or 30% with the exception of that mini pump it seems.

Ugh…that would put me off of AP pretty quickly!  I'm lucky to live in central Oregon where there aren't any mosquitos worth mentioning.   I think that I've been bitten maybe 5 times in the last 13 years compared to being eaten alive in my backyard in central Tucson where they thrive during the summer.  The Oregon mosquitos leave a sting that only itches for 15 minutes…then it's gone.  The Tucson mosquitos attack mostly ankles and feet and the sting itches down to the bone for 2 weeks.  It's bad.

I hope you guys in bug country can find a good solution!

I'm still looking.  A bee suit seems like the next thing to try.  Between bug spray dissolving plastic pretty bad and thermacells being toxic to wildlife my only good solution has been a combo of winter clothes, box fan, bug spray on my face and the bug lamp.  It gets to be a bit much to haul out at night.  Winter clothing plus a bee suit mask might be a good option to get rid of the bug spray.  Just have to get a little sweaty.

I actually got into AP in January because I got a dobsonian last fall, loved it, but got destroyed by mosquitoes.  Now I can operate inside other than the PA and focusing.  I didn't think I would get 100-200 bites in the <10 minutes I spent outside though.

There's a bayou a few hundred feet from my house, plus it rains often and the ground is always saturated, so there is always standing water close by.

If I make a pier, then I can take care of the PA portion.  Maybe an auto focuser is in my near future.

I can vouch for the effectiveness of Thermocells. Have used them during mosquito season on our back porch and they are very effective repellents. They use a synthetic compound called allethrin - 

https://en.wikipedia.org/wiki/Allethrins

For those not familiar, the applicator is a small electric or butane burner that heats a small strip of material with the repellent. The butane powered hand unit is quite effective for ~10-15 ft circle (like around a patio table.) They need to be used with care, but are highly effective.

Note from Wikipedia on allethrin toxicity

The compounds have low toxicity for humans and birds. It is highly toxic to fish and aquatic invertebrates. At normal application rates, allethrin is slightly toxic to bees.[1]Insects subject to exposure become paralyzed (nervous system effect) before dying. Allethrins are toxic to cats[2] because they either do not produce, or produce less of certain isoforms of glucuronosyltransferase, which serve in hepatic detoxifying metabolism pathways.[3]

Being from south Louisiana, I understand this post haha. I would lose about a quart of blood per night. I found the best option to be a "mosquito" hunting suit. It's just a very fine mesh jacket and pants set. If that wasn't enough, I would then spray the strongest bug spray I could find (usually OFF brand). I found the dry version to be less annoying. That usually fixed the issue to an "acceptable" extent. Ultimately, there is no way to fully rid yourself of mosquitoes. Sorry for the bad news. Things like thermocells and fans are usually useless. The best option being make the time outside less and less by automation.

Hello Alex,
So they bite you, meaning, you are still delicious. 😎
In Japan, the most popular mozzie repellant is "katorisenko".
Please search the web with "katori senko mosquito coils".
If not available in your drugstore you can certainly buy it online.
When imaging outside I usually put it under the PC table.
It does smell a bit, but you'll get used to. The mozzies won't.
Works well for me, but I may not be as delicious as you are 😉
Cheers, Robert

DEET definitely works, but watch out, it reacts with any kind of plastic. The mosquito coils work as well. An alternative option is ground coffee that you light. It works similar as the coils, but has "no chemicals" in.You are just getting a bit smoked :-)
I tried some alternative options as well like essential oils, but these did not convince me. When working in Africa (Malaria…smile I use DEET - no compromise, at home I use/play around with alternative options…
Cheers, Rob

I'm in a densely populated area of Tampa and they're awful here, I can't imagine how bad they must be in a swampy area in Southern Louisiana. It's gotta be similar to the Everglades. Anything >= 15% DEET works well for me as long as I cover myself in it…exposed skin and clothing, they have no problem biting through t-shirts or anything else that's comfortable to wear in the heat. I do have a slight reaction to it though, skin feels warm, hands feel puffy. I'm wearing long sleeves, pants, and a hat to minimize the direct skin application but I don't know if I'll be able to stand that in July thru Sept. The bee keeper hat sounds like a good idea.

I've never had any luck with any of the burners/devices/etc unless it's completely calm outside, which is rare here.

I just picked up this hobby too. Summer nights here, especially July thru Sept, are pretty uncomfortable. Between the heat, humidity, mosquitoes, and roaches that will define the next several months it should give me a good idea about my actual passion/interest level.

I use rynoskin for ticks and other annoying things.

The Deep Woods spray can in my car says 25% DEET. As I said before, this works for me. The thing is to make sure EVERY part of exposed skin in covered.  So I spray on fairly liberally and rub to make sure. For face etc., spray on palms and apply.

We have our share here once summer is upon us and we use different versions of what the guys mentioned earlier. I think it is best to minimize the need for you to be outside. Not a mosquito repellent but it goes hand in hand with one I guess?

You mentioned PA and focusing, maybe consider investing in an autofocuser, and a polemaster? My routine usually is setting up before dusk while mosquito activity is still low, turn on everything and go in. Once it's near astro dark, I start the PA routine with the polemaster, and if needed (usually I keep my tripod/mount outside covered), I go outside and tune the PA in under 1 minute. The rest is done strictly from inside, I only go out again in the morning to take the OTA inside and cover the mount.

I also take my flats inside when I move the OTA in. Having a flat panel lit up is an invitation to all mosquitos in the neighborhood.

It depends a lot on your location and what type of annoying mosquitos you have around but in my case, I have severe mosquito issues when imaging in my rural dark Bortle 4 skies country site. I try to setup and prepare my rig way ahead of civil twilight but keeping every optical piece of equipment with the cap on to prevent mosquitos and any bug debris landing on the surface of expensive goodies. Then go get something to eat, spend some family time indoors and back out after astronomical darkness. Mosquitos love to get their lunch at twilight and then leave when it is totally dark and chill outside. I would still use spray repellent and you may want to get as many skin covered with clothes as possible (including a baseball cap in case you are bald like me). Consider covering your body even during summer warm nights.
At home and mountain areas, it is tarantulas and scorpions that sometimes want to attend the star party but those invertebrates are great fellows simply because you are not part of their meal. I would not bother too much about them but mosquitos are a totally different thing.

Very simple solution Alex after fighting them for years: remote access your laptop that is hooked to the mount from the inside. That works of course only at home. On the road maybe from the car? Otherwise … Deep Woods Off was for me always perfectly, and that as example in late spring in Algonquin Park, and whoever was there knows what that means, there a billions of them!

DEET works for multiple mosquito species here in NY.  I hate having it on me, so when I observe, or hike or run in the woods, I spray it on a baseball cap.  The hat eventually gets stiff and tacky, so I assign one as my sacrificial bug cap.  I worked with some researchers who found that 30% DEET works just as well as 100%, but the higher concentrates are more associated with adverse effects when applied to the skin. DEET is also the only repellant that seems to have some benefit against black flies in the Adirondacks.  Those flying tormentors can turn a sane person into a babbling idiot.

Whew, lots of replies today.  Thanks for all the feedback and apologies on quoting everyone in a single post, but I prefer that over a bunch of different replies.

Ahh, I had forgotten about the mesh sets.  I will have to look at them again as an option along with some of the other suggestions.  Thanks for the reminder on them!  I have lived in many places, and south Louisiana definitely takes the cake for mosquitoes out of everywhere I have been.
Hello Alex,

I will look into this product.  I'm not sure I will find in local anywhere, but if it works well, then maybe ordering it will be an option.  Thanks for the suggestion!

Hey George!  I lived in Brandon for many years.  I used to fish every night after school at a pond by my house 5th-7th grade and then junior and senior years in high school when we moved back.  My father was military and worked at MacDill.  Maybe it was because I was younger, but I can honestly say it never came close to comparing to where I am now.  Even down in Okeechobee I've never seen it as bad as it is here.  I bet the everglades are probably comparable though.

This looks very promising.  I might order some this week after I read into it a little.  I just got home from work.  Thanks!

I use SharpCap Pro for my polar alignment.  It really only takes a minute for me to do it.  The focusing is less than a minute.  I just usually stand outside while I do the alignment, then go to a bright star, calibrate PHD2 guiding, get the camera focused, and then plate solve my way to the target.  I could go inside between and limit my exposure, but I also like being outside during the plate solving just to make sure I don't get any snags on the first movement each night.  I did a bunch of cable management, so this really shouldn't be an issue, but as people say, better safe than sorry.  This whole process usually takes 5-10 minutes.  I often take my flats inside.  I typically never leave my equipment outside overnight though.  It just seems too risky in my climate.  Also, after 2 AM there's often so much dew/humidity that you can't see anything anyway.  I hadn't seen much value in an auto focuser shooting with my DSLR, but now with my new mono camera and filter wheel it might be a worthy investment and help with mosquitoes, too.  I'm also trying to be budget conscious as I have already doubled it in a matter of a two months lol.

I looked at the area on satellite, and I have talked to others that have been there.  There is lots of water around, so I would imagine it would be bad.  Part of the problem is I am pretty close to the Gulf of Mexico, so we have mosquitoes April-November.  Folks in my neighborhood will actually run inside at dusk even in the middle of a conversation because you will get swarmed bad enough that it blots out the sun a little.  I am pretty much remote other than PA and focusing.



Also, for all those that mentioned DEET or Off Deep Woods, maybe my blood is just nectar to mosquitoes because even when I bathe in it I still end up covered in bites.  I used 30% DEET last week and it didn't do a thing for me, although I was in shorts and a t-shirt last week since I didn't know if they would be bad yet.  Even last winter when I used DEET with jeans, a jacket, and hat, I still got chewed on pretty badly.

Again, thanks all for the suggestions.  I have some more research to do!

I live in New Hampshire's mosquito infested woods.  In winter it's very cold here.  So, outdoors, the choice was bug bite or frostbite.

My solution was to go indoors.  I built a heated cabin out in a field and an observatory 30 feet away to avoid heat effects.  I connect the two over an Ethernet cable.  Very comfy. Includes a window bench suitable for sleeping, a wine rack and a small fridge for beer and snacks. A WiFi repeater brings Internet 500 feet from the house.

I back onto a forest here in Canada so mosquitos can be annoying and have found that thermocells work decently, also 'Great Outdoors' repellant lotion (find it in Hiker shops or Amazon). The best solution was putting a concrete pier in my backyard. I use a Telegizmos 365 cover on it year round, just bringing in my cameras each night. A mini PC on the mount and TeamViewer delivers remote control via tablet when I need to be outside, or my desktop in the house.

Wow, that sounds really nice!  Do you have any pictures you can share?  If budget weren't a concern I'd like to build a nice two car detached garage/workshop with a half level with either a walk out balcony or observatory dome.  Since budget is a concern for what I would want (plus building codes to try to stand up to hurricanes), I might settle for a pier as a short term option to reduce time outside, since after the initial bit I run everything from the couch in the living room.

Not sure how it would work on your property but look up Talstar-P.  I use it twice a season around my house and telescope shed to make those tasks bearable.

Do you broadcast spray your entire yard or a perimeter around your equipment?  I'm skeptical it would work where we live, but I'm open to trying almost anything, especially if it just requires an application once every few months.
