Mosquitoes are also more active at dusk and just after daybreak and are more prevalent around salt ponds, standing water and places with dense vegetation, especially the beach near where the sand meets the vegetation. You can lessen your chances of a close encounter with mosquitoes and their pesky cousins no-see-ums by avoiding walking in those areas at those times and by refraining from using perfumes, colognes, after-shaves, scented hairsprays and similar items as the “sweet aromas” act as an attractant. The use of a good insect repellent will be a big help.
