Controlling mosquitoes

Bug zappers provide a satisfying sizzle but biting insects generally make up less than 1% of bugs zapped.

Mosquitoes breed in still water so empty saucers under potted plants and fill with damp sand, rake up wet leaves and install a fountain in ponds to keep water moving. Consider using netting from camping stores as a barrier.

 

Reduce numbers by planting citrosa geranium, marigold, catnip and rosemary in the garden close to the house and outdoor entertaining areas as these plants emit odours that mosquitoes don’t like.

 

The most effective insect repellents are those containing DEET, a synthetic oil that scientists say works by masking the smell of human sweat, the scent that alerts mosquitoes to the presence of a meal.
