Rats are attracted to dwellings in search of food and shelter, particularly during the colder months. You can minimise the problem by keeping your yard clear of derelict vehicles, building matter or other junk. Protect all food sources so that rats cannot get access. If you are concerened about a rat problem contact Council on 07 885 0340 and ask for the Environmental Health team.


Ants can be controlled by using bait. Most hardware stores, garden centres and supermarkets have commercial ant poisons available. Several baits should be laid out in small containers like milk bottle tops, etc, as ants from one nest will not eat with ants from another nest. Poisons are slow acting, taking several days to kill the nest.


Bees that are swarming and have not yet found a permanent home are not usually dangerous to people. It is normally only bees that have established their colonies and are making honey in hives that require removal by qualified personnel. Swarming bees can be picked up and removed by a bee keeper. A list of people providing this service is available in the local directory.


Live cockroaches can be killed by spraying or fumigation methods. However, egg cases are immune to poisons and cannot be destroyed. As cockroaches have a six week lifecycle, a regular six weekly spraying/fumigation programme must be implemented to destroy cockroaches developing from the egg cases. It may take several months to totally eradicate the problem. Contact a commercial pest control firm listed in the local directory.


Fleas can be eradicated by using flea bombs, available at supermarkets and hardware stores. Alternatively, you could contact a commercial pest control firm listed in the local directory.


In most situations, flies can generally by controlled by spraying or swatting. If flies are coming from a known source like a compost heap, rubbish bags or a property, then nuisance conditions may exist. In these cases, contact one of the Council's Environmental Health Officers who will investigate.
