Default Pyrethrin thermal fog & sprayer OT

I know I don't have to inform most that it's mosquito season once
again. My porch is swarming so that I can't come in the door without
invited guests.

A friend of mine runs fans on her porch to keep the critters away. I
had thought about installing a ceiling fan by the front door and
running it night and day. Has anyone else tried this with success?

I don't have any standing water on my property, but I do have loads of
woods around that stay dark and damp.

In cruising the posts on this group I saw a mention of Pyrethrin
thermal fog being used. Where would you get this and a fogger that
would be useful for an individual?

I have often wondered what they eat when I'm not around. (O:

They drive me nuts in the evening when I want to swim. Have been considering
placing a tee in the return line from my filter and setting up a spray to
produce a continuous spray over the center of my pool. I tend to think that it
would lower the water temp and some water loss to evaporation.

Anyone ever try something like this?

What country are you in? There are about six dozen entries in
http://dir.indiamart.com/indianexpor...repellant.html
(Indian manufacturers of Pyrethrin mosquito repellent coils,
mosquito repellent gel, mats, multi purpose sprays, "All kinds
Of Mosquito Repellants Like Mats, Coils, Liquid Evaporator,
Liquid Spray And Aerosol, Electrical Device For Mats", etc.)
Pyrethrin coils and vaporizers are in common use there, and
seem to work. Although pyrethrin is not allergenic (per
http://www.getipm.com/articles/pyrethrin-shampoo.htm ) it
can be contaminated with pyrethrum, which is. Also the coils
(like http://doityourself.com/store/6033815.htm ) aren't healthy
indoors: http://ehp.niehs.nih.gov/docs/2003/6286/abstract.html .

If you put a valve on the sprayer so that you could turn it off when you
were not using the pool, it would keep evaporation and cooling to a minimum.
Whether you'd have enough pressure in the filter return to get a decent
spray is another question.

Or you could build a belfry, cast some nice bells for it (metal content...)
and invite a bevy (flock?? herd???) of bats to take up residence in it.

A friend of mine was once the curator of a museum that sat alongside a river
at the edge of a forest. We spent many a pleasant hour sitting on the
museum porch on a warm summer evening, talking and watching the bats soar
overhead. But then some high ranking idiot in the employ of the state
(which owned the museum) ordered the bats exterminated. In short order, the
swarms of mosquitos soon became so thick that it looked like a bit of fog
rolling in. Needless to say, there was no more sitting out on the porch...

Home Depot, etc. At least here in SE Florida. Search for "fogger" at
http://www.homedepot.com/ .

It is just a mineral oil fog generated by a small propane burner. There's
a small amount of pyrethrins in the oil, but as far as I know it's just the
oil that is annoying the critters. No different that what's been around
for the last 100 years. Inside my screened enclosure it is good for
purging any insects that have "leaked in", but in the actual open outdoors,
the slightest air movement dissipates the fog and brings in a fresh wave of
insects.

You guys make me grateful I live in Western Washington! We have mosquitoes here
too, of course. I think I saw one a week or two ago.

A world with no skeeters...I can't imagine!
I have looked into building bat houses, only to do some research and
find that some group had built them with absolutely no takers.
I see bats from time to time in other parts of town, but they must not
like the menu offered in my yard as I haven't seen them here.
Has anyone tried the device called mosquito deleto?
Those mosquito magnet type devices are SO expensive and the reviews
show at best a mixed result. That's why I thought the fog might be
worth a try!
Maybe I should ask what HAVE y'all done that worked?

I think the mosquito is the state bird in these parts.....
I utilize insect WMD's in a propane hot fogger that my dad got
for fishing camp up in canada years ago. The fog mixture is Vapona
and diesel. Chlorinated organo-phospate ---kick ass stuff
that leaves em twitchin on contact . Hard to find the concetrate
these days, a gallon will last several lifetimes. The residue
last for a while too. We'd fog the camp site and it would
be bug free for several hours, not recomended breathing the
stuff.....Choose between a little bug spray or a west nile
vacation hmm

I have one of these (mine is MUCH older)
http://petsupplies4less.com/sbsite.p...Propane+Fogger

It has a propane heated tubing coil that heats a .5% pyrethin/99.5%
mineral spirits mix. Squeeze the trigger, it shoots out an oil vapor
that hangs in the air and clings to shrubbery. Smell is noticeable, goes
away fairly quickly. Knocks down mosquitos in the air, penetrates into
shrubbery where they hide, has some residual effect.

This unit is too small to provide much in the way of long term control.
Seems to help if you plan an early evening yard party. Fog everything
for 200' heavily just before guests arrive, you can expect a noticeable
reduction in the critters. Not complete control but maybe half to 3/4
are gone. It does work.

Pyrethin's are nasty. We had a woman that had a reaction to the stuff at
a party. Not sure I'd want young kids running around in the stuff on a
reagular basis.

Forgot to mention: the propane cyclinder screws into the back of the
unit (see the fitting at 30 degree down angle from body), green
container holds a quart of insecticide. Return unused insecticide to a
marked container.

I bought a Burgess fogger and thermal fog from W.W. Grainger. The
fogger is a cheap vibrator type sprayer that sprays thru a electrically
heated tube. The thermal fog liquid can also be used feeding it into a
lawnmower engine exhaust.

If you have a W.W. Grainger catalog, it may not be listed. It is an
item they only carry in the summer. Or that used to be the case. I
have not looked lately.

In 1987 we did some remodeling that temporarily left small openings to
the attic. Bats moved in and when we finished the remodeling and
evicted them, I built a bat house so they would stay around. Well, of
course they didn't use the bat house! For 11 years it was empty and
then they moved in. They moved into the attic in a matter of weeks, but
it took them 11 years for the bat house!

Our small-town weekly newspaper is called "The Mosquito" in recognition
of the town's most prominent resident. A lot of people buy mosquito
magnets and a lot of them wind up at the dump! Something as expensive
as a M-M at the dump can only mean one thing: it didn't work. However,
some people do have success with them.

My wife came home one day with a box - a small bug zapper - and an indoor type.
Both are at the shop. Both do their job.

The indoor is great - it is a down draft fan and a light. The basket taking in
the bugs keeps them there until they starve. I just emptied it and the basket
(1 1/2" deep and 4 or 5 inches in diameter) was full of flying beetles and the nasty
types that sting. It sweeps the shop clean at night - being the only light.
I pour it out on cardboard for the birds after a week or so. Funny - they like
the free lunch.

In North Texas, Fort Worth: I bought a used Mosquito Magnet Pro last

screw-the-bottle-on the-hose skeeter sprays and have a couple of

I live in Austin, the home of Bat Conservation Intl and the largest urban
bat colony in the world. What I have been told is that the key to
successfully getting bats to move into your bat house is to hang more than
one of them, facing different directions, at different heights, in different
locations. The issue is that bats are very choosy about the temperature of
their homes, so you have to experiment until you find the location with the
best temperature. Once they have picked one, you can move the other houses
nearby. It is not only the actual temperature, but also the way the
temperature changes over the day and evening that matters to them...

This may seem fussy, but the benefit of having bats is huge - they eat a ton
of bugs...

They also need a "Clear field of fire" - and open area with something 30
feet of drop, so they can swoop down and out. Once I read that
(somewhere) I realized my house probably wouldn't work. Too many trees.
