What smell do mosquitoes absolutely hate?

What smell mosquitoes absolutely hate includes several strong scents that interfere with their ability to detect humans, though no smell provides 100 percent absolute repellency forever, but some are highly effective. Mosquitoes hate smell of citronella, which is oil from lemongrass, as it masks carbon dioxide and body odors that attract them, which is why citronella candles and torches are popular, though protection is limited to few feet. They also hate lemon eucalyptus oil, specifically oil of lemon eucalyptus, or OLE, containing PMD, which is EPA-registered and CDC recommended, providing up to 6 hours protection and is considered most effective natural repellent. Other smells mosquitoes hate include lavender, peppermint, eucalyptus, cedar, catnip which contains nepetalactone that is 10 times more effective than DEET in lab, basil, and rosemary. DEET and picaridin are synthetic but most effective. For yard, garlic spray is hated by mosquitoes. Mosquitoes rely on olfactory receptors to find CO2 and lactic acid, so strong smells overwhelm those receptors. Planting mosquito-repelling plants like citronella grass, lavender, and basil around patio helps reduce mosquitoes somewhat, but not as effective as barrier sprays or personal repellent. Most effective smell for personal use is oil of lemon eucalyptus, while for yard, cedarwood and garlic are hated. Combining smells with removing standing water is best approach.
