Spiders
Except for poisonous spiders, such as the black widow and
the brown recluse, spiders are not harmful to humans. When it’s important to eliminate spiders, chemical control is
used, along with destruction of webs and eggs. Since they feed on insects, measures that eliminate unwanted insects will also
reduce spider populations.
