hi.
i just want to give an update on the roach
situation because it's the end of the summer and proper communication on
the subject is a lease obligation on my behalf.
i
guess it would have been the end of may or the beginning of june that i
blocked the holes up and did a significant amount of spraying around
areas that i thought they might be considering nesting. as mentioned, i
didn't ever get the impression the nest was in the apartment, but that
they were coming through holes in the wall from somewhere else. the
concern was to stop them from nesting. i have not seen an adult roach in
the apartment since the beginning of june, so this has been mostly
successful.
i think what i did eliminated everything
except any possible egg populations, which i couldn't get at (there may
have been some deep under the sink) and which the spray would not be
effective against. so, the concern was that they would repopulate as
they hatch,
however, that doesn't seem to have
happened. i've seen a handful of baby roaches in odd places that
probably were hatched in the apartment, but they've mostly been found
dead.
i also noticed a spike in the centipede
population after i sprayed, but this is probably a function of them
coming out looking for food. when you see a lot of centipedes, it means
you probably have roaches near by; certainly, there is a source of
insects for them to eat. that also indicates that the roach population
was dwindling or gone. note that the centipedes will also eat the egg
sacs. based on what i can observe, it seems like they may have gotten
almost all of them.
the next thing i noticed was that
the spiders started disappearing. i'd rather have a few spiders near the
windows than flies floating around, so i prefer not to kill them, but
the centipedes must have been eating the spiders. now i've got more
flies than i'd like, but hopefully the spiders come back...
the centipedes then mostly disappeared altogether, indicating the food source had been exhausted.
it's
still too early to declare them gone. i think they must be around
somewhere, not too far from here, but they don't seem to be present in
the apartment right now.
we'll find out in the next few
weeks if they have another entry point, as the temperature begins to
fall and they seek refuge indoors for the winter.
