- In a previous insect killers the spray is aimed at a bug and fired. However through the act of diffusion the spray particles will move to an area of lower concentration. Therefore the spray may have been aimed at the fly may not hit its target as the spray is spread elsewhere.
- Some types of bug spray repel insects like insect repellent, whereas some completely immobilise them. For instance you may read the can and it says that the active ingredient is an “ acetylcholinesterase inhibitor ”. Acetylcholinesterase is the chemical in bug spray that breaks down acetylcholine. Acetylcholine needed to send the messages from the insect's brain to all of the vital organs. Once the insect is sprayed, the chemicals begin entering the body, and slowly begin blocking the neurotransmitters. As the chemicals begin entering the body, the acetylcholine is interrupted, and the bug will begin losing control of its extremities. The signals become more unclear, and as the bug moves its legs forward, they are unable to move back again. This process continues as the inhibitor moves further into the insect's body. As the chemical enters further into the body, the signals from the insect's brain is inhibited from reaching the vital organs as well. The circulatory and respiratory systems are unable to respond to the commands coming from the bug's brain and begin to shut down. The insect will lose control of all of its motor functions and dies quickly.
- Invented by Professor John Hughes, charged droplets are attracted to flying insects, such as houseflies and mosquitoes. Faster rates of insect paralysis and higher mortality are the result. Many other domestic applications for the technology are now being considered. This 'Smartseeker Technology' offers many advantages over conventional sprays as the droplets emitted from the nozzle reach their target more rapidly and efficiently. The electrostatic charge means the spray has 'wrap-around' capabilities, giving coverage to those hard-to-reach places. More accurate coverage also means there is less wastage, offering a more environmentally sensitive delivery system.
- The first stage of the process involves tribocharging (frictional charge generation) between two components of the trigger mechanism. Charging of the product is simultaneously achieved as the liquid is atomised in the high electric field created by one of the tribocharged components. Using this technology, effective targeting and wrap around characteristics can be transferred to just about any aqueous spray.
