Recently one of the pipes in our kitchen broke and with some accidental neglect some of the wood underneath the sink started to roat and stink wich attracted flies and no body I know likes flies in their kitchen or any where for that matter. After the wood and sink was fixed there was still a small amount of flies. There are a few commercial ways to get rid of bugs, like those fly tapes and toxic sprays etc. I didn't like the idea of the fly tape simply because its nasty and the toxic spray is not going to fly with me because of the.. well... toxions...
My solution to the pesty problem is very very simple and I would like to share it with you so you too can benefit from the simplicity!
We all know that bugs are attracted to light and sweets, so in this build I used both to attract them to my trap. The trap is a 2L pop bottle with a fan on the side and a 10mm white LED inside of the cap and on the inside there is maple syrup. The white LED is used to attract the bugs, the fan sucks the bugs in and the syrup keeps the bugs down,






UPDATE: Some one just informed that not all leds attract bugs. The led I used however does attract bugs. There are a few factors that depends on the relationship between attraction. I would recommend using a small light bub instead of the led. But if you are using a led that attracts than nevermind. Just thopught I would share that with everyone.

Step 1: Supplies.

one 2L pop bottle
one 10mm white led
one 3.3 voltage regulator
one 12volt dc cpu fan
one SPST switch
wire
power supply (either 12 volt ac-dc supply or 9volt battery)
NOTE: the voltage regulator is for the LED. The led I used operates on 3.4 volts.

Step 2: Schematic.

The schematic is very simple. The power input can be from 5 volts to 12 volts. if you exceed you could destroy the fan. I forgot to put the switch in the scchematic. it should go before the regulator

Step 3: Putting it together.

Now its time to put everything together. Take the wrapper off of the bottle and cut a big enough hole for the fan, mount the fan using a small piece of metal (see picture) then run all the connections, put the white led in the pop bottle cap by drilling a small hole for the wires. Since there are very little componets a pcb isn't really needed, I soldered everything together then covered up everything with electrical tape. The assembly is pretty straight forward.

Step 4: DONE!

You are done! now just fill the pop bottle with a little bit of thick maple syrup and turn it on. I added a 9volt battery snap for portable use. I forgot to cover how to clean it. once it has been used for a while just unscrew the cap, add some water and pour the syrup out. Before doing that disconnect the power source then let it dry before next use.
