Increasingly customers are interested in alternative pest control
techniques that do not use man made chemical insecticides.
These are available, made from naturally occurring products
such as pyrethrin insecticides which are formed from Chrysanthemum flowers.
There are various insecticides that work by physical interference with
the insect, eg;
Diatomaceous earth damages the cuticle (insect skin) and affects water
absorption, killing the insect through dehydration.
Insect Eco reduces the surface tension of water using plant oils, which
in turn affects the spiracles (breathing tubes) causing the insect to drown.
If you want to avoid all chemicals (natural or man made), there are
various techniques available, such as:
These can be used for moths, fleas, flies, cockroaches,
wasps, etc. They generally work with an attractant – light,
heat, food or pheromone, the insect being caught on adhesive
or in a liquid.
Heat and steam can be used to treat a variety of insects.
Rats, mice and squirrels can all be caught with traps and cages. (Positive Environmental do not approve of rodent glue traps and believe that they should be banned.)
Most of these alternative techniques do have their limitations.
For example the flea life cycle includes eggs and larvae that are
not affected directly by the initial treatment, therefore a residual
insecticide is needed to kill the flea as the adult hatches. Using
these alternative techniques will therefore usually require more
than one technique.
