How about growing your own Mosquito repellent? We've noticed an upsurge in mosquitos recently probably due to the rain we've had so anything that helps discourage these bites is fine with me. Studies have shown that Lemon Thyme to be one of the best natural repellents, equal in effectiveness to some concentrations of DEET which is found in over the counter insect sprays and lotions. Actually, any lemon scented herb will do well. Lemon Verbena is one of those as is Lemon Balm. The Lemon Verbena grows well around here.
However, it isn't enough to just have these plants growing, to keep mosquitos off your skin you need to rub the leaves on exposed extremities. This has to be better than using insecticides.
