This web site gives you extensive information about the safety of the pesticide (Foray 48B) that is used to eradicate gypsy moths in Washington. Most of this information cannot be found on the Department of Agriculture's (WSDA) website. They insist there are no significant health, safety, or environmental problems caused by this pesticide (despite mounting evidence and worry in the scientific community), so they will not give you any methods to protect yourself or your family.
There will be at least three sprayings. If the spray is aerial, it will be done by helicopter. The helicopter will fly very low, about 100-150 feet off the ground, spraying a mist of Foray 48B. This will be done sometime between 5am and 7am in the morning.
If the spraying is from the ground, spray trucks will come to
your area during the work day. The applicators will come onto your
property and thoroughly spray all vegetation, including any vegetable
gardens. If a garden is covered, they will tear off the covering to get
access. If there are higher bushes or trees, they will use nozzles that
can produce up to a 50 ft. stream. Some fine mist will be produced and
drift around the neighborhood as well as infiltrate your house; the
drift will not be as far as with an aerial application.
To avoid the spray, you should be out of the area before the helicopter or spray trucks show up. Close all openings in your dwelling. The spray is in the form of microscopic particles, so it may stay in the air for many hours. It is probably safe to return 12 hours later, but some pesticide will have been trapped in your home (even though it was closed up - this has been shown by studies discussed elsewhere on this site), so open all doors and windows to air it out first.
To find out when the sprayings will happen, you must call the
WSDA at 1-800-443-6684. Tell them you want to be notified the day
before each spraying.
Aerial spray will drift out of the spray zone (see 2006 map for Capitol Hill) for at least
1/2 mile, and
maybe farther depending on the winds. If the wind is blowing in your
direction, a fair amount of spray may be in the air even a mile away.
