The Outdoor Lifestyles section of last issue
features an Alaskan winter adventure. Mosquitoes aren’t
much of a problem in winter, but if you visited Alaska in the
summer, you would find them something of a nuisance.
Why go to Alaska for a good nuisance. If you have hiked or picnicked
on O‘ahu—especially the windward side—you have
had to deal with the mosquitoes. These pests can turn a fun outing
into a day of misery. Worse than the nasty bites and the ruined
experience, mosquitoes can transmit deadly diseases that can

Insect repellants come in many forms, from sprays to wristbands.
The effective ones all contain one of two types of prevention,
man-made or natural. The man-made one is the chemical DEET
(chemical name, N,N-diethyl-meta-toluamide). There are several
alternative natural substitutes, but the most common ones are
a eucalyptus-based formula or citronella oil.
DEET is available in several brands. OFF® and Cutter are
common. Insect repellent with DEET prevents the mosquitoes
from biting by masking the odors people emit that attract mosquitoes.
Mosquito repellants that come with DEET are effective for a
variety of different time periods, varying with the strength
of the application from a mere two hours to a whopping six
hours for a single application.
Natural alternatives for mosquito repellant were created
because of health concerns about the chemical DEET, especially
is used on children. However, despite the fear regarding
DEET, it has been found to be safe as long as it is used
with the instructions on the label.
Mosquitoes are most likely to attack in the morning during
the hours after daybreak and in the late afternoon in the
hours just before dark, and these are the times during which
should be used regularly. However, mosquitoes breed in stagnant
water, and if there are ponds or abundant puddles in the
area, mosquitoes may be active and numerous all day long.

mosquitoes can transmit, see the sidebar this page.
