Wasps:
Elevated wasps nests (including larvae and adults) can easily be
removed by using the Sierra with extension wands. You can reach
up l5 feet or more and suck up chunks of the nest and larvae with
the open end of the wand. Do this late in the day or very early in
the morning when the wasps are settled in their hive. If the nest is
inside a foundation wall block, the wasps can be sucked into the
wand extension as they are returning to the nest. Leave the mo-
tor running when the bag is removed. Put the paper bag inside a
plastic bag and seal it. If the client objects to a liquid drench, use
the Sierra to suck out adult ground nesting wasps late in the after-
noon. Dusting wasp nests afterwards with a desiccant can control
additional insect activity.
Bees:
Bees are beneficial and should be protected except in instances
where the customer is in danger of being stung. DO NOT attempt
to remove a swarm hanging on a tree limb with a vacuum cleaner
unless you are properly protected from their stings. The noise of
the motor will aggravate bees and they will probably attack.
To control bee nests inside walls, check instructions in the Mallis'
Handbook for Pest Control or Smith and Whitman's NPCA Field
Guide to Structural Pests.
House Dust Mites:
Just about every home in the world has dust mites. They live in
dust balls, sofas, mattresses, and even rugs. Their principal food
is the thousands of microscopic particles of skin which people
and pets shed daily. These tiny pests are the most common cause
of indoor allergies. After ten years, dead house dust mites could
comprise one sixth of the weight of a well-used sofa cushion. Just
sitting on the cushion spews a cloud of the troublemakers into
the air. Simply attempting to kill the mites with a miticide is not
enough to prevent the allergies. The microscopic particles from
dead bodies, eggs and feces will be constantly recycled by a con-
ventional vacuum cleaner. The High Filtration Disc available
for the Sierra traps and retains these particles. Shop vacs, which
pick up liquids, actually aerosolize the allergens and intensify the
problem.
