Neem oil is a natural vegetable
oil used since antiquity as an
insect repellent for both people
and food crops. Researchers at
the Malaria Institute have
discovered that neem repels
the
mosquito that causes malaria for
up to twelve hours as well as
biting flies,
sand fleas and
ticks. In fact, several
compounds in neem are more
effective insect repellents than DEET yet are much safer.
