MOSQUITO-LESS. STOP Mosquito before they can bite! Mosquitoes are 10,000 times more sensitive to garlic than humans. Their life-cycle normally takes place over a number of weeks and within an area 100 sq yds. Once they leave the area they prefer not to return. Just spray Mosquito-Less on your property, trees, shrubs, gardens, lawn, fences, out buildings and low areas. In minutes after this ready-to-use natural garlic oil product is sprayed, mosquitoes will leave. This will keep mosquitos away for up to 4 weeks. No need to worry about a lingering smell of garlic. The odour will dissipate in 4-5 hours.
