Tackling and getting rid of mosquitoes is quite a tough task especially when you don't have access to expensive commercial machines. Even the marketed sprays & medicines are toxic chemicals and very harmful to health. In this instructable, we will learn how to make Mosquito Insect Killer at home. This mosquito killer machine attracts mosquitoes due to ultraviolet light and kills them instantly as its metal grid emit high voltage electricity. This mosquito insect killer uses a mosquito swatter racket to kill mosquitoes, thus making it safe for children and adults.

Step 1: Watch the Video

A detailed video tutorial is the most simple way to understand a "How To" project. In this video, you will find all the steps needed to make a mosquito insect killer at home. However, make sure to visit step 2 for additional information and images.

1. Open all the screws of a mosquito swatter racket and pull the plastic cover.

2. Desolder the battery & other wires from the circuit board.

3. On a piece of cardboard, mark the boundary for the metal grid of the mosquito racket.

Note: Make sure to watch the video to get visual clarity.

4. Refer to the image above and using a stationary knife, cut the cardboard, so as to fit the racket over it.

5. Using hot Glue, attach the racket to the cardboard.

6. Cut cardboard pieces of adequate size to close the machine later at the end.

Now, visit Next step to see how to modify the circuit board for use in Mosquito Insect Killer Machine.

Step 5: Modify the Circuit Board

1. Short the toggle switch on the circuit board, so that the circuit gets turned ON when the power button is switched ON.

2. Remove all the indicator LED's from the circuit board.

3. Connect a 3.7v Li-Ion battery to a TP4056 charger module.

4. Connect the charging module and the Li-ion battery to the circuit board.

5. Also, attach an ultraviolet LED to the battery, that lights up when the circuit is turned ON.

6. Test the operation of the circuit by shorting the capacitor with a metal object.

Note: Make sure to watch the Video to get better clarity of the procedure.

7. Solder the wires of the metal net to the circuit board.

8. Make slits in the cardboard to access the On/Off switch and micro USB port for charging the battery.

9. Using Hot Glue, attach the circuit to the cardboard and close all sides of the machine using cardboard pieces of adequate size.

Step 6: Time to Test the Machine

Our Mosquito Insect Killer machine is now ready. Turn On the circuit and place it in a dark room, the mosquitoes will get attracted to the light and will instantly get killed to due high voltage in the metal net.

<p>Have you tought to put this post in the Before/After Contest?</p><p>This is a very cool idea, i have a Mosquito Swatter that stopped working, but now it&acute;s gonna be a mosquito killer.</p>
<p>Thanks, Mosquito Killer now entered into contest.</p>
<p>You have my vote, hope you win.</p>
<p>Thanks a lot.</p>
<p>Thanks :)</p>
<p>Hey , thanks for the instructable :)</p><p>I made a 3D enclosure version with half raquet to make it smaller and more ... 3D hahaha. You can see it / download / print it at: <a href="https://www.thingiverse.com/thing:2365279" rel="nofollow">https://www.thingiverse.com/thing:2365279<br></a></p><p>Im having troubles with my electronics, the NPN is getting super hot and stop working after 2 or 3 minuts , any idea? Should we upgrade it with an arduino and a &quot;shots counter&quot; to know all the kills? Could be epic XD</p><p>Thank you again <br></p>
<p>Maybe is about the 3,7v instead of the 1,5x2v batteries?</p>
<p>Nice 'ible. Placing a plastic container of baking soda with a little vinegar in the box would help attract more mosquitos by making carbon dioxide, but it would require access to change the contents. FYI, HarborFreight.com sells a very similar swatter for under $6. (I don't know what shipping costs are if you don't have a store near you)</p>
<p>A mixture of sugar water and bread yeast should produce a steady supply of CO2 that could survive a couple of days before needing to be replaced.</p><p>Take a look at this:</p><p><iframe allowfullscreen="" frameborder="0" height="281" src="//www.youtube.com/embed/GxYPTpMSmbU" width="500"></iframe></p>
<p>Nice recipe for CO2, gotta try it.</p>
<p>$6.99 flat-rate shipping</p>
<p>They go on sale for 2.99. I often get 1/2 dozen... great gifts.</p><p>Mine is 6-7 years old.</p>
<p>Your instructable is well done.<br>Unfortunately this is NOT at all effective at killing mosquitoes, so you should remove reference to mosquitoes. It is, however, very effective at killing other insects that are beneficial.<br>See: <a href="https://en.wikipedia.org/wiki/Bug_zapper"> https://en.wikipedia.org/wiki/Bug_zapper</a></p><p>Quote: &quot;External traps<br>These traps are not effective at killing biting insects (female mosquitoes and other insects), being much more effective at attracting and killing other harmless and beneficial insects.<br>A study by the University of Delaware showed that over period of 15 summer nights 13,789 insects were killed among six devices.<br>Of those insects killed, only 31 were biting insects. Mosquitoes are attracted to carbon dioxide and water vapor in the breath of mammals, not ultraviolet light.<br>However, there are now bug zappers that emit carbon dioxide or use an external bait, such as octenol, to better attract biting insects into the light.&quot;</p>
<p>Here in Mexico, there is a &quot;mosquito hour&quot;, a common term refering a period of time between 6:30 p.m. to 8:00 p.m. where you have to run safe inside the house, because we have a lot of cases of SIKA, DENGUE and CHIKUNGUNYA.</p><p>In that very same &quot;moquito hour&quot;, close to my home i saw a plant with a dark cloud of mosquitoes, were so many that i had to stop and watch for a while.</p><p>I remember have read about that in the DAY plants convert CO2 in Oxigen, but at Night they do the opposite. That kept me thinking, there must be some plants that produce more CO2 than others.</p><p>Shortly after that the city management trimmed that plant, and i&acute;ve been waiting it to regrow to use it to make a mosquito trap.</p>
Excellent observation skills!<br>We are lucky here (NZ). Where I live you can count the mosquitoes that invade your house - less than one a day (vision of half a mosquito flying around :-).<br>Good luck
<p>What about the sand flies though .. I'd love something to kill sand-flies at my house (Nelson, NZ).</p>
<p>Sandflies, sigh...<br>Here's a quote, not sure of its origin, but probably true:<br>&quot;One way to deter sandflies in NZ is to walk around carrying a penguin as bait, while eating garlic, covered in Dettol and baby oil.&quot;</p>
<p>When it does regrow. please post a picture here.</p>
<p>exactly! I was wondering how this beautiful project is even useful? Seems like a waste of time and effort.</p><p>I catch bugs, flies and moth with my ultraviolet light zapper on the patio but never an single mosquito!! </p>
Great idea. Awesome project
<p>Thanks</p>
<p>Nice work and reusing to the max from existing infrastructure! Liked it!!</p>
<p>Thank you</p>
<p>Brilliant idea TechGenie :)</p>
<p>Thanks</p>
<p>Great, I'll test it soon. One tip. Bugs are the most attracted to UV-A light, 365 nm to be exact. You can add</p><p><a href="https://www.amazon.com/Ultraviolet-Lighting-Electronics-Components-Emitting/dp/B01AUI4VTM/ref=as_li_ss_tl?s=aps&ie=UTF8&qid=1495544282&sr=1-1-catcorr&keywords=LED+5mm+ultraviolet&linkCode=sl1&tag=goodtech07-20&linkId=7296cb817a7e4c100e1386c12bc899cd" rel="nofollow">https://www.amazon.com/Ultraviolet-Lighting-Electr...</a></p><p>as second led, because 365nm is invisible to humans.</p><p>I also found this:</p><p><a href="https://www.superbrightleds.com/moreinfo/shop-lights-garage-led-lighting/led-z-bug-bulb-by-nebo-led-bug-bulb-porch-light-mosquito-killer/3610/7809/" rel="nofollow">https://www.superbrightleds.com/moreinfo/shop-ligh...</a></p><p>:)</p>
<p>Not all bugs. And absolutely not mosquitoes.</p>
<p>Very nicely laid out instructable. However it wont kill many if any mosquitoes. Mosquitoes are not attracted to UV light, or any other color for that matter. It should attract some moths and various other insects, but only if the UV light is strong enough for them to see decent from a distance. (They use fairly strong UV lights in bug killers for that reason). The HV section of the bug killer should be strong enough it can sit unattended and kill bugs. Even if they temporarily short out the grid it should be strong enough to burn them off. A protective, non conductive (and fire resistant) screen should be placed a bit in front of that grid to keep children and animals from getting a shock. The HV section of an electronic fly swatter is not going to be very effective on moths. It is safe for animals etc. due to the same fact though.</p>
Not however safe for cats who are likely to blow their noses off...
<p>Wow, i like it.near UV LEDs attract many insects, mostlymoths.</p><p>But Mosquitos are more attracted by smells like co2 and IR </p>
<p>Just an FYI -- this is similar to the bug zapper lights you can buy. They, and this, do not discriminate in the bugs attracted and killed, which include fireflies, ladybugs and other beneficial insects. This is why I quit using a bug zapper decades ago.</p>
<p>I really need to make one of these, they're so bad this year!</p>
