Choose feeders on poles that rats and mice can't climb, with wire mesh or weighted
perches that exclude larger birds and squirrels. A seed catcher beneath to prevent seed
from spilling on the ground is also a good idea. Keep your feeders meticulously clean,
and clean up any spilled seed and hulls daily. Sometimes landlords are concerned about
general sanitation, since rotting seed hulls building up near a building's foundation can
cause structural problems. If you can assure your landlord that you take his concerns ser-
iously and are willing to do the work necessary to prevent problems, you may be able to
change his mind.
Q I have wasps in my birdhouse. What should I do?
A
Wasps and bees seldom usurp boxes from nesting birds. They are mostly found in
empty boxes. If these insects are found in a box, it is best to let them be and not take
any active measures to exterminate them. Instead, wait to clean them out in the fall when
the weather is cooler and their activity has halted. You can prevent wasps and bees from
establishing themselves by applying a thin layer of soap (use bar soap) onto the inside
surface of the roof. This will create a slippery surface between the insects and the roof of
the box. Never use insecticides in any nest box.
