Re: HOME REMEDY NEEDED FOR INSECT AND RODENT PROBL
There's also a rather 'natural' way: Check the ants for type,
if not 'biting', invite them in! They keep your house clean
from residues that would ohterwise attract other insects.
Ants have the rare 'feature' of not carrying parasites (normally), and poses no threat whatsoever. (Still talking about
non-biting variants) Spiders can carry parasites, but seldom
any that attacks people. They do, however ,keep the house free
from flies, mosquitos etc... If you don't want the spiders,
bring in a colony of 'lagartos' (Don't know the name in english,
it's a miniture lizard, about an inch long, and actually quite
cute!)
Previous suggestions of a cat (or rather two-three) are perfect!
Only alternative (if cats are impossible because of allergies etc), are snakes. There are a lot of non-poisonous to low-poisonous snakes around. Check if they will breed on your
grounds, if so, go for it! (Will also provide delicious meat
for garden parties. Cats don't breed fast enough for that.
Some people would also object to eating cat-meat.)
All-in-all: I don't know of any man-made chemical that is
as efficient as 'biological warfare' when it comes to
unwanted guests in a permanent habitat. What Tom said
about boric acid is true enough, but you'd have to repeat the
treatment over and over again, exhausting either your funds
or the local supply...
Good luck! /Gunnar (Jarabacoa)
