Mosquitoes can spoil outdoor enjoyment, but a simple DIY garlic spray offers a natural solution to repel them and hinder their breeding. Research from Yale University confirms that garlic's active compound, diallyl disulfide, triggers rejection responses in mosquitoes, preventing them from mating and laying eggs in treated areas. To create the spray, mince 4-5 garlic cloves and boil them in 2 cups of water for 10 minutes. After cooling, strain the mixture and pour the garlic-infused liquid into a spray bottle. This environmentally friendly repellent should be applied around the perimeter of outdoor spaces, focusing on entry points like doors and windows, and should not be sprayed directly on skin or furniture. For optimal results, reapply every 2-3 days or after rain. The garlic scent fades within hours for humans, but its mosquito-repelling properties linger for days, making it a practical and effective solution for outdoor living areas.
