The U shaped bulb in my bug zapper is a blacklight bulb. I cant find
replacement bulbs locally. To mail order one will cost me around $34.
I'm not willing to pay that much, particularly since the zapper only
seems to kill moths and night bugs which are not a real problem anyhow.
I hung it to hopefully kill flies. I'm not saying it's worthless, but
it's not worth $34 for a bulb which will probably only last a year.

However, I have not yet ripped the thing apart, but I'm assuming it's
made with some sort of transformer to create the high voltage in the
screening around the bulb. Then there's this florescent blacklight bulb
with associated ballast.

If this is the case, why must the bulb be blacklight anyhow? Why cant I
just wire a common lightbulb socket in the fixture and put a small CFL
bulb inside the unit? After all, my white porch light brings in bugs
like crazy. Why not use a plain CFL to attract the bugs?

And, if there is some important reason that it must be blacklight,
Walmart sells a blacklight CFL bulb for $7 or $8. That much I'll pay.

My question is why they use blacklight bulbs when a plain white bulb
draws bugs?

UV seems to be the part of the light spectrum that flying insects are
attracted to. If you have a Light Bulb Depot close to you, you may be
able to get a replacement bulb there. ^_^

Can't answer you question about the blacklight. It probably attracts
bug but does not give such a bright light to people around it where it
could be bothersome.

As for being worthless, it is worse than worthless. It drew more
bugs to the nearby house than with no light to zap them.

I hung one on my detached garage figuring it would keep bugs away from
the door screen. Instead of about 3 to 5 bugs on the screen, there
would be 15 that chose the house light over the bug zapper. It
attracted them from the woods more than house lights. Big ass beetles
and moths. They do nothing for mosquitoes.

I find bug zapper bulbs on www.ebay.com for much cheaper than that. I've
found the bulbs at Home Depot, and Walmart.

As to UV spectrum, I'm not sure.

A plain flourescent bulb will work as well for attracting the bugs but a lot of people dont like having the bright light on especially at night. If this isnt a problem that is the way I would go. Yeah those things dont work so well for flies. Ive heard of people putting fly bait in them to attract the flies. Also remember that the number of insects these things kill to to available population is tiny. What these things usually do is attract more insects than they kill. They do work well indoors and screen porches where you have a limited and depletable population. These things can be a lot of fun, I've connected them to my garbage can to discourage raccoons and connect it to a bare wire running down the corner of my sofa to discourage the cat. I have even succesfully used one as an electric fence charger. Take the bottom off one and hang it over a pond, the fish will love you for it and show their appreciation my learning to bite even a bare hook.

The bulb is not very bright to the human eye. It will still be seen by the
bugs.

Unless the bug light is inside a closed in area, you will attract bugs to
it. The way to use one outside is to place it away from where you are at.
Then some of the bugs will be attracted to it and not to where you are.
Just run the thing when you are outside.

This is one of the things to sell and not to use.

the propane powered bug zappers are recommended to be placed away from
where you plan to congregate. they draw the bugs away from your people,and
zap them out there. (the propane is to make CO2,the attractant.)

I hung one on my detached garage figuring it would keep bugs away from

what attracts mosquitoes is carbon dioxide,that you exhale.

There are two kinds of bugs - day fliers and night fliers. The bug zappers
are designed to attract night fliers and then electrocute them. The UV bulb
appears bright to night fliers and so they are attracted to it. Day fliers
see UV bulbs as dim just the way people do. House flies are day fliers.

Any other kind of bulb than UV appears less bright to night fliers; but
white light from CFLs has some attraction because it has a lot of blue.
Incandescent bulbs not so much. The yellow so-called "bug lights" are
virtually invisible to night fliers.

House flies and mosquitoes don't respond strongly to light. House flies
respond to odors and mosquitoes are attracted by carbon dioxide exhaled from
breathing animals, including people.

So, the trick is to figure out what kind of bugs you want to attract and
where you want to attract them to and that's about all you can do.

From my experience, they brought in more bugs than having no zapper.
Tried it for a couple of years and I'd never have one again.

My main problem is flys (day fliers). I'm on a farm and the livestock
attract them. I cant sit out on the picnic table or lawn chair without
having flies crawling all over me. I cant relax outdoors because I swat
flys constantly. Everytime I go in the house, 5 or more flys also enter
because they are flying around the door and sitting on the house. I've
found little commercial stuff that works very well. I dislike using
chemicals around both people and my animals. Yet I've tried the
"outdoor foggers". They work for about 10 minutes, and I'd go broke
spraying more than the house door and around the picnic table. I have
sticky fly paper all over the farm. They do their job, but only in a
small area and fill up fast. I tried those "Stinky bottle traps". I've
found them to be hard to get working, hard to maintain, nasty to smell
(when they do work), and can not be put where most needed (like the door
or picnic table) due to their odor and nasty appearance.

What has worked slightly is one of those battery operated electric fly
swatters that look like a tennis racket. I sit it near where I'm
sitting or next to the house door, take the button down so it stays on,
and watch the flys get zapped. (The problem there is that I'm replacing
the batteries every 3 or 4 hours). That is what got me to bring out the
plug in bug zapper which has been sitting in my garage for years. But
as I said before, before the bulb burned out, it only killed those
harmless night fliers like moths, (which is why it's been in the garage
unused, because I dont really care to kill those bugs, I want to kill
flies).

I know I'm not the only person with extreme fly problems. Farms are
known to have them. But I'd sure like to find some better methods to
control them. There just dont seem to be anything sold that works well.

About 10 bucks at any electronics department.

I'd like to add the suggestion of a three sided housing that makes
the
light come out in only one direction. If it is hung a hundred feet
from
the house, and the light faces the house, the bugs near the house
will be attracted to it, but the bugs in the three other directions
will not
"see" it...... this can be accomplished easily with a little
aluminum foil
and a few rubber bands.
Perhaps someone can suggest a further improvement.

Correct. I watch where the flys tend to "sit". That's where I put it.
Lately I noticed that using a small pail seems to attract them. I put
the zapper over the pail and get more of them. I'm not sure why?

My sis lived in Paso Robles, CA. Each evening, the frogs would make a
circle around the bug zapper, and catch the little BBQ'ed critters as they
fell. There certainly were a lot of small zaps, and occasionally the big
fat ones.

We had bark beetles about twenty years ago. Up in the National Forests.
When they first appeared, they wanted to spray them. No, said the tree
huggers. So, they killed up to 75% of the trees. They just had the
Shingles Creek fire up there, and the cost was up in the millions. The fire
could have actually been stopped in the first 24 hours, but the government
regs said only one dozer with one blade could go two feet deep. As it ended
up, it burned 8,300 acres, and cost $8 million. Today, the forests up there
are from 35-75% dead, and just waiting another lightning strike. There are
thousands of mountain homes in the area.

Would that qualify with what you are asking?

good one but there's no doubt in my mind they cut down on numbers of
flying critters.

No, they aren't very effective on skeeters nor flies but that's not to
say they aren't helpful on various moths, flying beetles, etc., etc.,
etc., ...

Which of the "various moths, flying beetles, etc" threaten the health,
well-being or comfort of anyone?

Just wondering.

Jim

We had bark beetles about twenty years ago. Up in the National Forests.
When they first appeared, they wanted to spray them.

Would that qualify with what you are asking?

It would if those beetles were attracted to a black light-- I don't
think they are.

Those lights attract more skeeters than they kill. Get one for all
your neighbors.

Why not wire in a universal power supply with the proper voltage?
About 10 bucks at any electronics department.

I've been planning to do this. I need a 3 volt DC supply. Most of
those transformer wall warts are 5, 6, 9, 12, or higher voltage. I have
a whole box of them and none are 3v.


Try your local Goodwill store
Many have a whole slew of smaller transformers
Surely one of them would be a 3Vdc

good idea. you can also get multi-tap transformers @ radio shack or
similar places.

The U shaped bulb in my bug zapper is a blacklight bulb. I cant find
replacement bulbs locally. To mail order one will cost me around $34.
I'm not willing to pay that much, particularly since the zapper only
seems to kill moths and night bugs which are not a real problem anyhow.
I hung it to hopefully kill flies. I'm not saying it's worthless, but
it's not worth $34 for a bulb which will probably only last a year.

However, I have not yet ripped the thing apart, but I'm assuming it's
made with some sort of transformer to create the high voltage in the
screening around the bulb. Then there's this florescent blacklight bulb
with associated ballast.

If this is the case, why must the bulb be blacklight anyhow? Why cant I
just wire a common lightbulb socket in the fixture and put a small CFL
bulb inside the unit? After all, my white porch light brings in bugs
like crazy. Why not use a plain CFL to attract the bugs?

And, if there is some important reason that it must be blacklight,
Walmart sells a blacklight CFL bulb for $7 or $8. That much I'll pay.

My question is why they use blacklight bulbs when a plain white bulb
draws bugs?

And i found a good one here https://gadgets-reviews.com/review/6...g-zappers.html so i think it is a good device. As i know they selling it on the amazon.
