Little friends underfoot - creating and preserving invertebrate habitat in your home
One
of the long-accepted axioms of home ownership is that bugs simply do not belong
in them. Every hardware store and
home center has shelves full of lethal chemical weapons designed to annihilate anything that suffers the
twin misfortunes of being born very small and wanting a nice place to
live. It’s deeply engrained in our
culture, an attitude learned almost as soon as we learn to walk. Somehow it just seems so natural
to stomp on little things.
Thoughtful
homeowners are starting to question this industry-encouraged campaign of
extermination that we wage on our tiny fellow creatures. Some are even asking the question, “Why
can’t people and bugs learn to coexist? Isn’t there room for everyone?”
Centipedes,
spiders, ants, termites, cockroaches, beetles, silverfish, houseflies, mites -
there’s a world full of fascinating insects anxious to share your home; a world packed with drama,
with armies on the march, skillful predators and elusive prey, grazing herds,
solitary dreamers, lightning fast runners and ace dive bombers - even loyal
friends.
Consider
the cockroach. Traditionally
despised, squashed and poisoned at every opportunity, they are in fact
easy-going and quite intelligent, with their own distinctive personalities, and
not at all difficult to train. Because of their long history of conflict with humans, they tend to
scatter when the light comes on, but once you show them that your intentions
are friendly and that you have some tasty food to share they’ll actually come
out from their hiding places when you call them. They’re happy in any warm, dark place, and they genuinely
seem to like people’s company. With very little encouragement they will give back as much as they
take.
Another
favorite in our home are spiders. No special preparations are needed to attract them, although they
appreciate a bit of a draft, and of course a steady supply of food. We leave our screens open in the warm
months to attract tasty tidbits inside. Then, if our little arachnids become too abundant, we just close the
screens.
There
are ways to share your home with little creatures without feeling overrun. As with any animal, you need to be very
clear about setting limits and boundaries. The who and what of mealtimes has to be firmly
established. For instance, unless
their appetites are properly channeled, termites and carpenter ants can cause
quite a bit of inconvenience for owners of wood houses. One successful strategy for enjoying
the company of these captivating social insects without losing your house
entirely is to construct a floor level viewing chamber full of standard 2 x 4s,
but lined on all sides with heavy gauge sheet metal and capped with thick plate glass for easy
viewing. Set the plate glass in a
tightly fitting steel channel welded to the sheet metal with an arc welder (welders can be rented, if you don’t
have one on hand). Install a water
source to keep the wood moist - a must for carpenter ants (although termites
aren’t so fussy). I use lengths of
1/2” rigid PVC tubing with a 1/32” hole drilled into it about every foot,
capped at one end, with a shutoff and a connection to the house water supply at
the other end. Once a day I’ll
briefly open the shutoff - just enough to dampen the wood. If you get the moisture just right,
you’ll get some gorgeous fungi as an added bonus. You can also hook up a timer and servomechanism to the
shutoff, so that the whole operation could be done automatically - consult a
commercial greenhouse supplier for parts. A small, tightly sealed hatch is also a good idea for termites, so you
can feed them fresh lumber when the original supply is gone.
Mr.
G. H. of Abilene, Texas writes me about an interesting ant training experiment
he’s been working on for the last five years. Every evening before bed he spreads refined sugar over his
stomach, being careful to leave a thin trail of it from his bed to a known ant
colony behind his baseboard. At
first the ants were shy, but now when Mr. G. H. comes into his bedroom the
workers rush out excitedly, aware that their snack is on it’s way. They have lost any fear of climbing up
on him, and a bold few will even pluck small crumbs from his beard. The colony has grown quite large, and
early this summer sent out a flight of queens inside the house - a sure sign of
trust.
As
we say in our house: Think before
you thwack.
