While most solutions that address the mosquito menace are at most temporary, you should know that there is a solution that can keep your surroundings mosquito free for up to a month at a time. Yes, you can now repel mosquitoes for up to a month by using mosquito dunks. Mosquito dunks have been in use for over a decade now, and continue to find an increasing number of users. They primarily address the mosquito menace by striking at its very core; mosquito dunks work by killing mosquito larvae before they can mature into mosquitoes that bite. Mosquitoes eggs can often withstand extreme conditions and then when they fiind the water conditions to be right, they hatch into larvae. It then takes them around a week in order to develop into the blood sucking creatures that they are generally regarded as. Killing mosquitoes as larvae is one of the best ways to address mosquito problems. Mosquito dunks generally come in a solid form. The ingredient that works in killing the larvae is a form of Bacillus thuringiensis which according to wikipedia Because of their specificity, these pesticides are regarded as environmentally friendly, with little or no effect on humans, wildlife, pollinators, and most other beneficial insects. The dunks are placed in water where the mosquito larvae grow, and work by releasing the Bacillus thuringiensis into the water. As the larvae start eating the Bacillus thuringiensis which is mixed in the water, they start to die. When placed in water the dunks are generally effective for up to 30 days. Also, since these dunks come with a hole in the center they can easily be suspended into water using stake or a string. To say that mosquito dunks are effective would be quite an understatement. More and more people are turning to this natural mosquito repellent when it comes to addressing mosquito infestations, and this isnt without reason. Also, if you worried about having to use an entire dunk even though you have only a small area that needs to be dealt with, you should know that it isnt necessary that you use an entire dunk at one time, and you can always break enough off to use in accordance to your requirement. For instance, using a fourth of a dunk is enough for an area of up to five square feet. Besides, owing to the versatility of mosquito dunks, they can be used in places as big as ponds and as small as flower pots.
