Dealing
with Unwelcome Visitors
Living in a warm climate brings with it some
problems, one of which is how you learn to live with unwelcome
visitors to your home or apartment.
Ants
Understanding how ants live is key to dealing
with them. Ants are social insects which live together in
cooperative, intermingling colonies. The colonies may range in
size from hundreds to millions of individuals, depending on the
species. Within each colony are different types of individuals,
each with a specific function. All ant colonies contain one or
more queens, whose primary role is to lay eggs. The eggs hatch
into white, grub-like larvae that later transform into adult
"worker" ants. The workers feed and care for the queens and
developing brood, and are the ones seen foraging for food and
water, often at great distances from the colony. Ants lay down
invisible odour trails, which the workers follow between food
and the nest. In many species, the trail of ants is distinct
enough to be followed back to the nesting location, or to where
the ants are entering from outdoors.
If you want to get rid of your ant problem on a
long term basis the best solution is to use bait. These are
available in plastic containers that you place somewhere along
the ant trail and you can buy them from supermarkets and
ferreterias. Initially these will be increased activity as the
ants are attracted to the bait. They will then take this back
to the nest where the bait will affect the whole colony. You
need to allow around a week before you should start to notice a
difference. In the meantime it is important to not spray or
kill any of the ants around the trap as they are doing the work
of dealing with the problem for you.
Another option is to use a deterrent. If the
ants are entering your property through doorways you can get a
spray that sop them coming in. One example of this is Laca
Rastreros, a spray available from ferreterias. This is an
insecticide that will kill on contact but which also leaves a
residue that deters the insects. Spray this across thresholds
and leave to dry. Keep your pets away from this area for at
least an hour. This should also help to deter other insects
such as cockroaches.
Mosquitoes
Mosquitoes, luckily not the malarial variety,
are a problem here, especially when the wind drops. As
mosquitoes do not live in colonies like ants, you cannot
destroy them at source. Insecticide sprays will kill any that
have already got into your home, but then you will have to keep
all the windows and doors closed to prevent further ones
entering. Unfortunately as the nights are warm you want to keep
the windows open, so you may want to consider some of the
deterrents available.
Electric plug ins which release a deterrent
odour can be very effective. However, this can be expensive if
you leave them on all the time, and painful if you forget to
plug them in. One option is to have have these plugged into
timers in the main living areas of the house which helps them
to last longer and which gives you protection at the times when
you need it. The plug ins and refills can be bought in
supermarkets and timers can be found in ferreterias.
Mosquitoes hate the smell of lemon, in
particular citronella. Yellow candles that give off a
citronella fragrance are available from most supermarkets,
often in attractive terracotta pots or as tea lights that you
can put in your own containers. These are particularly useful
for using outside at night.
It is only the pregnant females that need
blood, and this to help the development f their eggs. Some
Sonic repellents use this principle to transmit the sound of a
male mosquito, which the pregnant females in their current
state, are keen on avoiding. Others give out the sound of a
dragonfly, the mosquitoes main predator. These have had mixed
reviews though as to how effective they are.
If you are getting bitten while you are out on
the town, there are a number of chemical insect repellents
available, but many people don't like using these or are
sensitive to the chemicals they contain. Instead you can try
putting a few drops of citronella oil in your body lotion. This
oil can be found in health shops. One commercially produced
product that just uses natural ingredients is Al Fresco. This
can be bought from
http://www.alfresco.uk.com/ It is expensive, but smells
wonderful! If you don't want to cover all your body, you can
use a repellent soaked wristband, such as these available from
http://www.mybeautysecrets.co.uk/Product.aspx?ID=1178
A more permanent solution of you own a property
here is to have mosquito screens installed on all your windows.
These can be made to measure for your windows or you can buy a
standard size from shops such as Norte y Sur and cut it to fit
yourself. Many of these open and close so that people can still
exit safely in the case of a fire.
