Introduction: Fly Trap

Picture of Fly Trap

This a fly trap to control our flies. We get them because we have cats and thier food attracts LOTS of flies. If you have a dog you may have the same problem.

Step 1: Materials

Picture of Materials

We Need the following:

Step 2: The Motor Mount

Picture of The Motor Mount

Here we need to make the motor Mount.

Step 3: Mounting the Motor

Picture of Mounting the Motor

In this step we mount the motor in the motor mount.

Step 4: Mounting the Fan

Picture of Mounting the Fan

Here we mount the fan that actually make the motor usefull.

Step 5: Mounting the Cone Onto the Lid

I didnt make this instructable until after I made the fly trap and didnt have the materials to make a new one. So I havnt shown you how to make the cone bt it should be simple enough :D.

Step 6: The Bait

Picture of The Bait

This bait smeels horrible so dont sniff it. The more water you put in the weaker it is. You only want flies around you section to smell it so dont make it too strong.

Step 7: Completing the Trap

Picture of Completing the Trap

In this tep we complete the trap itself.

Step 8: Attach the Electronics

Picture of Attach the Electronics

I will explain each picture:

1) Attach aligator clips to the motor wires.

2) Attach the swith to ONE of the motor wires and put another clip on the other side.

3) That Says DC.

4) Power Supply.

5) Weird end to have but it is for my slot cars.

6) Here is where those nails can help.

7) You should have 2 free clips, clip them on here.

8) Mmmmmmmmmmmmmmmmmmmmmmm Plug it in Plug it in (It on and ad haha)

Step 9: Watch the Vid

I wonder if this would work on dragonflies, they have been breeding in our greenhouse.

Seems to me like you fixed the wrong problem.
What you need to do is try to transition your cat(s) away from canned food onto dry food. Not only is it cheaper, it's better for your cat too. For treats, give them leftovers from your meals (remember to cut it out in nibble-sized pieces, cats can't chew well).
Nutro and Hill's are examples of great products.
With dry food you can feed your cat for less than 50 cents / day.
Canned food can easily cost a dollar or more, depending on quality and can size. Not to mention that it stinks.
Only thing to make sure is that you cat(s) always have water (canned food consist of up to 90% water)

ClockRed (author)Yonzie2007-10-07

Please don't give out misinformed advice. Cats are not like dogs where they drink water often. Cats need to get their water from their food as they drink little compared to humans and other animals (raw meat is most preferable, canned meat is second preferable). Their systems are not made to digest carbohydrates like humans, so pumping them up on CHEAP DRY FOOD filled ash, and grain fillers is damaging to their health... Diabetes, dandruff, kidney failure... Anyway I'm done, just do a little research before advising cheap dry food. Also Microman the fly trap is a great idea! I wish I saw this solution over the summer!

Yonzie (author)ClockRed2007-10-08

If you'd actually read my post you'd realize that I was not recommending cheap dry food, but high-quality stuff. I totally agree in the "don't feed your pet crap" department. The above suggestions is what cat breeders (purebred cats, not random mixed ones) around here feed their cats, and I am pretty sure they know what's good and what's not. Also, with the abundance of flies near the cat food, I'm not sure I'd be comfortable feeding my cat wet food. Think of all the fly eggs and crap. How long does it take for the food to become inedible?

catrinadaz (author)Yonzie2012-05-11

I fed my cats dry too until I read this..very enlightening

microman171 (author)ClockRed2007-10-07

I have a 'non-electrical' version which is much better. It has no moving parts. Somebody else beat me to posting on here

dudaott (author)Yonzie2007-11-23

Yonzie, sorry to say that, but dry food affects the cat's kidneys badly. And the canned food doesn't smell that bad, if it's a good brand. Nevertheless, it's VERY IMPORTANT all the pets get enough FRESH water ever. Warmest Regards!

punkinthegreat (author)2011-06-02

those poor poor flies.

ayoung5 (author)2011-06-01

Just get any PET bottle cut it in half, invert the top and stick it down. Put 2 inches of water and a small amount of raw meat (or anything that pongs) in it and you're done. A few days in the sun and it will be teaming with flys (and might make you dry reach too).

No Power. No fans. No time wasting. Easy peezie.

Cher Bro.

What part?

Kallan (author)2009-01-12

You could try attaching the fan to a Solar panel instead. So that way, the hotter it gets, the more flies are around, the faster the fan spins. I don't find there are many flies around during night when the fan won't spin.

microman171 (author)Kallan2009-01-12

I say go for it! To be honest, this is not a great way of removing flies... The motor is far too loud, so it scares off the flies...

donhave (author)2008-12-07

dude!!! hows about using macro when taking photos close-up.

microman171 (author)donhave2008-12-07

Sorry, I didnt used to know what macro was.

a9fan1959 (author)2008-07-10

we have three cats, and 2 dogs i know what you mean, dude.

bumsugger (author)2008-04-04

Not so sure I'd wanna make such a pro-active device to er,trap flies.Whats' wrong with a more "passive" instructable,looks kinda cute though,if'n you're a sadistic type,on the other hand,it just might take-off for the moon?

microman171 (author)bumsugger2008-04-04

I was bored on sunday and my mum was angry about the flies. So I make a more interesting trap. The noise stopped it from wokring :(

SeMi_AuToMaTic (author)2008-03-04

so here flys bob. he is a fly. he loves to annoy people. he just finished annoying rob, the human. so he flys and smells some wonderful bait. yum! my favorite brand! he says to himself so he flys down into the trap and the next thing he knows is that he's in 21 different pieces.

microman171 (author)2007-12-18

Or you could try my reasl method... Usually I get the bucket with lid, cut out windows and a circle in the bottom. then I cover the windows with mesh and make a cone with a small hole for flies put it on legs and voila, a fly trap. You put the bait under the trap and when the flies leave they get caught. When there is too many flies in the trap spray them through the windows then when their dead tip em out

mr_bojiggler (author)2007-12-18

DUDE!!!! Scratch all that! all you need is a container, a rubberband, some plastic wrap and either balsamic vinegar or rice wine case you havent figured it out, here you go: 1) fill your container up about 3 inches with the vinegar 2) coverit with plastic wrap and seal it with the rubberband, so the flies dont escape 3)poke a few small holes in the plastic that are big enough for the flies to get in...YOU ARE DONE!!!took all of 3 minutes...let it sit for a day or two and see the results! every couple of days you may want to change the vinegar out to keep the scent strong...This also helps if you have roaches! i did this about a week ago because my drain clogged and i had standing water for a few days which attracted all these bugs...after about 3 days i could not see any flies at all and after i bombed my kitchen with raid and cleaned out the cabinets, I found about 6 dead roaches and havent seen a live one since!!! or you could try this guys method if you got time to kill

Karim (author)2007-03-15

Whats the fan for?

microman171 (author)Karim2007-03-16

aIts so the flies get sucked into the bait. First the fly smells it then lands in the funnel and gets sucked down possibly shredded by the fan and then spat out into the bait

i make shooting things (author)2007-02-02

if you go to a hoby store you can get a quiet ducted fan and battry and stuff i think that would make it quieter and i little easy

Good Idea. Next time im in tauranga (it in NZ) Ill ask I if I can go there.

microman171 (author)2007-01-29

I was hoping you guys could help me develop it more. The hole thing makes a lot of noise and vibrates. If I wrap the motor mount tightly in a towel then i halves the vibration. How would I get even less?

jtobako (author)microman1712007-01-30

mount it in foam rubber or box it in and line the box with carpet or acustic tile. flex mount the fan and motor away from the cup-the thin plastic is acting like a speaker and amplifying all the noise.

microman171 (author)jtobako2007-01-30

If I do remount the fan then there is no suction therefore the flies dont get sucked in.

jtobako (author)microman1712007-02-01

you just have to isolate the fan from touching the cup.

microman171 (author)jtobako2007-02-01

But the fan isnt touching the cup. The reason I used this and not an ice cream lid and a PET bottle was because the pet bottle shrinked. The cup has atleast 5mm of clearance.

mewantbigboom (author)2007-01-29

now i can feed my venus fly trap!(no, really i have a venus fly trap)

mewantbigboom (author)crestind2007-01-31

oooooo i been searching for one that had all

Vermin (author)2007-01-31

You have an intake but no exhaust port. I cant see how this would work.

microman171 (author)Vermin2007-01-31

The exhaust is there. The flies escape into the bait. If you put a mesh on top of the food, then the liver wont drown.

homemade (author)2007-01-29

Neat trick but when I was in El Salvador on "Official Military Business" the locals filled ziplock bags with water and the flie checked out.

motley (author)homemade2007-01-30

how does that work??

microman171 (author)motley2007-01-30

I was thinking the same thing haha.

crestind (author)2007-01-29

Hope I can catch some mosquitoes with this.

microman171 (author)2007-01-29

Im sure yeast would work. In fact mosquitoes mite get sucked in better. But it would need a constant output or I mite not werk.

Fireinthedisco (author)2007-01-29

can we use yeast for mosquitoes and still get the same effect?
