Do-it-yourself effective electronic mosquito and insect trap

Hello, dear readers and homemade products!
As you know, mosquitoes, and sometimes other types of flying insects, are very annoying in the warm season. One of the most common ways to deal with them at home is the use of various insecticides in the form of plates with toxin, or repellents (repellents) in the form of aerosols, creams, ointments, etc.
It is clear that insecticides can destroy insects in confined spaces , although inhaling air with poison is not particularly useful. When resting in an open space, for example, on a personal plot in the evening, you will have to apply “cream-gels”. Again, many people have allergic reactions to these repellents.
Of course, there is another way to deal with annoying midges. Here they are no longer scared away, but on the contrary, they are lured into various traps. There are also several ways to do this – heat sources in the range of body temperatures, light and “aromatic” (chemical) baits.
In this article, Alexander, author of the YouTube channel “We Can Do Everything”, will tell you how to make an effective electronic trap for insects and mosquitoes.
An effective electronic trap for mosquitoes and insects with your own hands This project is very easy to manufacture, and it can be repeated at home.
The dimensions and “power” of the trap can be reduced or increased, depending on the tasks.
Materials required for homemade products.

Tools used by the author .
– Soldering station T12

– Electric jigsaw
– Turbine gas lighter
Manufacturing process.
So, first the master made the first part of the structure, responsible for the destruction of insects.
In fact, it is a high-voltage arrester device, between the electrodes of which such a distance is chosen that breakdown occurs only upon flight or contact with one of the insect's electrodes.
The master cut two disks from 10-mm sheet plywood using electric jigsaw . Holes for pins, wires and a container for bait made with a screwdriver.
Both discs are interconnected by four racks, the role of which is played by M8 steel pins (one meter is enough for all racks). Discs are clamped at the ends of the racks between a pair of nuts.
 An effective electronic trap for mosquitoes and insects with your own hands Before assembling the structure on steel pins you need to put on a glue-filled heat shrink tubing and warm it up with a hot air gun or a turbocharged gas lighter … The tube will serve as an insulator.
 Do-it-yourself effective electronic trap for mosquitoes and insects An effective electronic trap for mosquitoes and insects with your own hands A conventional wire with a diameter of about 0.5 mm will serve as electrodes. Large currents will not flow through it – only good rigidity is required from it so that the distance between them does not change. In addition, periodic cleaning of the electrode grid will be required – the wire must withstand this.
The author uses enameled copper wire, previously removing the varnish from it by firing.

To prevent the coils from moving, the author fixed them on the outside of the posts with a hot glue gun .
 Do-it-yourself effective electronic trap for mosquitoes and insects high-voltage wires are soldered to the ends of the wire electrodes and brought out through the holes in the cover.

It will also be possible to screw the legs to it. In addition, this pad will play the role of additional protection in case of damage to the insulator.

The lid remains removable – the bait will be poured into it.

In the upper and lower discs, 3-mm holes are made into which 12 ordinary welding electrodes are inserted.

For this, two rings were cut out of the same plywood, and fixed on the body.
The protective grille is fixed with the same disks.

He made printed circuit boards himself, and soldered LEDs to them.
It will be much easier to apply UV LED strip .

At the same time, this block will serve as a second, thermal bait. For this, the radiator was removed from the transistor and replaced with a copper strip. It will heat up to about 45-50 degrees and attract insects.
This strip will be located at the top of the case, near the LED assembly.

Factory traps use multipliers of 4, and this is not enough for instant destruction of the insect. It will smolder and smoke.
The multiplier circuit is assembled from 400V 0.1mF film capacitors , diodes 1N4007 (1A 1000V) .

The LEDs turned on, but the check for the presence of voltage on the grid must be done with extreme caution – it reaches 2000V! In this case, the author simply puts the tip of the screwdriver between the wires, and the discharge occurs.

It can be purchased at a pharmacy.

In the dark, this is accompanied by quite bright flashes.
So you can evaluate the efficiency of the installation without even looking at it.

The author draws Please note that such devices work well in the dark, and during the day their efficiency drops to almost zero.
