We have four cases of dengue here in San Ignacio and the big truck sprayer is working its way through town each evening. The adult mosquitoes like to
shelter inside damp dark places, urns, shadowed areas, etc. I'm spraying around outside my doors each evening. Also, I notice the screen doors are
not tight, so I keep my doors shut in the evening and just leave the windows (with tight screens) open. At dawn, mosquitoes inside the house are
drawn to the screen doors (if the solid doors are open) and I can spray them there.

A fact about screen doors and windows. They keep out flies but not mosquitoes. I was sitting next to an open window and watched one land on the
outside of my window screen. It pushed it's nose through the screen and pulled it's body all the way though and flew into my house. For mosquitoes you
need a much finer screen material like on mosquito nets.
The bitterness of poor quality remains long after the sweetness of low price is forgotten.

Three spray trucks were in BOLA this week. There are a lot of bugs here.

Has Dengue been this widespread in Baja before? I'm hoping the cooler nighttime temps (at least on the Pacific side, not sure about the Cortez side)
will hinder the mosquitos and slow the spread.

I was in LA Paz earlier this month and going back on Wednesday. I noticed that the mosquitos seemed a little smaller this year than prior years, but
the presence (quantity in the air) didn't seem more...about the same as last year.
Are these critters getting smaller? Seems like they are almost the size of gnats or "no see ums".
mulegemichael, does it seem like there are more of them this year?
WOW, just finished reading the article above. According to the article, deet can have long term deleterious affect on human neurological system.
Using deet in conjunction with sunscreen increases the human absorption of deet by 3 to 6 times.
I just bought some deet at 98.7% strength to take to La Paz.

I believe it's recommended to use bug spray with 30% DEET as an ingredient. You sure 98.7% is meant for direct use, not as one of several ingredients
mixed together?

The stuff I bought is "Sawyer, Premium MAXI DEET insect repellent" it is actually 98.11% deet. 4 fluid ounces in a mechanical (finger press) spray
pump plastic bottle. $5 or $6 USD. 10 hours protection against mosquitos. I think that I bought it at WalMart.
I read the directions and the many precautions that came with the product. It is, in fact, intended for direct application. No mention of mixing or
diluting the product. Many, many "don'ts". Very emphatic about not putting it near the eyes, mouth, ears, nose. Don't breathe it, don't spray in
enclosed areas, and don't use it near food. Can't even apply it under clothing. Don't apply on cuts, wounds or irritated skin. They recommend
applying it lightly and then washing it off with soap and water when you go inside the house. Also, you can apply to clothing, but caution you to
wash the clothing afterwards.
In my assessment, having read the above article, the precautions on the bottle seem to reflect the potential harmfulness of deet as disclosed in the
article. In my view, the tone of the precautions on the bottle confirm the info in the article.
Sounds like scary stuff. Glad all this was brought to my attention.

The standard OFF that they sell here works just fine if you reapply it every couple of hours. There is absolutely no reason to poison oneself with 99%
DEET.

I got dengue a few years ago in Manzanillo. It was super bad, then I got a little better, then wham! -- worse than before -- and it lasted longer than
normal. Turns out I got it twice. There are four closely related types, all transmitted only by two varieties of mosquito, day biters as mentioned
previously, outdoors for sure, but they also love the indoors and are hard to get rid of.
One type can be fatal.
For skeeter details, check out this write-up by the CDC. Full dengue data library at the CDC site too.

SO...i guess the question is here; do i want dengue or do i want deet...very complex...but to me, is a simple answer....i want deet...and i do not
want dengue.....and neither do you....it's not like we'll be bathing ourselves in deet..we'll be using it while we are outdoors, which, in my mind,
will be a very little time this time of year when there are millions of mosquitos out there.....let it dry out a bit and have a chilled adult drink on
the back porch....use deet....it works and i seriously doubt, at our age, if it will take any significant years off our life....but dengue
will...trust me on this one...

Life is about choices. One chooses, then deals with possible consequences. Michael is right on with regards to Dengue, having talked with those who
have experienced it. As an avid backpacker in the High Sierra, 100% DEET is the medicine of choice. Skin so Soft, etc. is apparent on fellow
backpacker's red blotchy skin and the ultimate request eventually for sharing of the 100% DEET cache. Roaming about in the jungles of Belize, about
the only time mosquitos were not biting was when you are rubbing repellant on the skin. Having used 100% for most of my life, I really have not
experienced problems with it except for a chemically melted watch crystal and the stink. Then again, maybe my memory is affected. As an aside,
friends who are rangers in Yosemite avoid 100% as they would be using it on a daily basis. But then again, there is no Dengue in Yosemite.

It is the Aedes aegypti mosquito that is the primary transmitter of dengue in Baja. Most of the other mosquito species there do not have the ability
to transmit it. When a mosquito first bites a person with dengue and picks up the virus it cannot immediately transmit it to another person. The
virus must undergo a replication phase in the mosquito before that mosquito can pass on the infection. This replication phase can take a few days or
more depending on the temperature. Also keep in mind that Aedes aegypti is just as happy breeding in homes as it is outside. That means don't leave
vases of flowers or plant saucers for more than a few days without changing out the water. As for repellents, DEET is still considered the gold
standard but there are others that work nearly as good like oil of lemon eucalyptus or picaridin. There is really no need to apply DEET at greater
than 30% concentration. All that gets you is a little bit longer protection. You can just reapply the stuff a bit more frequently using the lower
concentrations. Some of the more common myths that continue to show up but are not going to help much are UV bug zappers (make you think they are
working by zapping lots of harmless bugs but hardly any mosquitoes), citronella (barely works so hardly worth it), dryer sheets (no good for bugs) and
electronic or sonic repellers (totally worthless, don't waste your money).
