Where is the best place to hang a bug zapper? Position unit at least feet away from areas where your friends and family are likely to be.
Our bug zappers also work best when hung feet from ground-level. Why are mosquitoes attracted to light? Light neither attracts nor repels mosquitoes. The idea of mosquitoes getting attracted to light is actually just a misconception of the insect's disorientation towards the light prior to navigating their destinations. Some lights red and yellow however, can be used to make us less visible to these insects.
Are bug zapper lights bad for your eyes? UV lights are usually harmful. But, the one being emitted by your bug device would not be significantly harmful unless you are too close to it, facing it directly, and using it for too long a time.
But in natural order, we are not supposed to have UV exposure. Though negligible, exposure is exposure. How long is fideo good for? How do I reset my key fob after replacing the battery? Co-authors 9. For the injection moulded parts, the mould tooling and material cost was estimated by a local Indian manufacturer as well as a Chinese manufacturer.
The mould cost was divided by the mould life generally k cycles and added to the material cost to give the final cost. Assembly cost was not considered as this is dependent on the complexity of assembly, time taken per step, and region specific labour cost.
The BOM cost is an important consideration for any product as it determines the final retail price. Based on the cost of the plastic components from different suppliers, we get two significantly different estimates of the BOM of the mosquito racket.
This is also a big reason why China is the current manufacturing hub of the world: due to the availability of low cost manpower as well as access to a variety of manufacturing technology at low costs. Competition among manufacturers may also force them to reduce their profit margins, which is beneficial for consumers.
The device is a good example of an electrical product that packages its circuitry well into a useful form factor. The physical design appears structurally robust and will likely survive small drops and impacts.
The design also appears to be heavily optimised to reduce manufacturing costs for every component. This is expected, as the device has no IP to differentiate itself in a competitive market where price is a major purchase influencer. All the plastic enclosure parts are injection moulded, which is an economic solution for high volume production runs, and we see evidence of cost-cutting to further reduce the unit price.
The PCB is manually assembled and soldered, which may be an economical solution for the manufacturers. The design also lends itself well to reassembly and repair; so should your racket stop working, it may be an interesting project to figure out what component has stopped working and then replace it.
Common components that can fail are: the FE transistor, the battery, the plug contact mechanism, and the soldered connections. However, given the low cost of the device, many people opt to replace the complete racket when it stops working. The purpose of these teardowns is to help promote a culture of making by lowering the knowledge barrier required to design and create your own ideas and inventions.
We want this series to be a collaborative effort between T Works and our community and so we would love to hear from you! What are some products you would like to see taken apart? What sections can we add to our teardowns that would add more value to the maker community? Send us your comments, questions, and suggestions to teardown tworks. Municipalities often spray pesticides, particularly malathion , on a large scale in the spring and summer to eliminate mosquito populations.
DEET repels most ticks , mosquitoes and other biting pests. Be sure to read product labels for usage directions. Another means of personal protection from biting and flying insects is citronella oil.
Citronella oil is a product of several types of plants. It is an effective mosquito repellant in high concentrations, but individual plants do not make enough oil to be effective. Citronella can also be found in candles and torch oil -- both meant to be burned outside. If you like citronella, citronella wristbands give you an easy way to protect yourself on a personal basis.
Many people erect Purple Martin birdhouses or bat houses in the hopes that these animals will eat lots of mosquitoes. While Purple Martins and bats eat huge quantities of insects, mosquitoes are not a significant portion of their diet. Sign up for our Newsletter!
