Ant control Co Down

If your wondering how to get rid of ants in Co Down contact Truly Nolen


The commonest species that invades any property is the black garden ant, which is actually very dark brown in colour. All ants have the main divisions of the body (head, thorax, abdomen) distinctly separated by very narrow waists and have a sharp elbow joint in their antennae. They are highly organised social insects. It is the foraging worker ants that invade buildings in search of food. These are from 3 to 5mm in length and are attracted to sweet food items, which they take back to the nest to feed to the larvae and queen.

The ant eggs sold for aquarium fish are actually the pupae. Flying ants are the reproductive males and females. These mating ants are winged and have a nuptial swarming flight during only a few days in July or August. Mating takes place in the air and the female then seeks out a nest site where she stays for the winter, laying eggs the following spring in order to start up a new colony.

Bed Bugs

A common pest once associated with unhygienic surroundings is now prevalent due to increased travel and therefore spreading the bedbug from country to country. These bugs still occur with regularity, particularly in multi-occupancy buildings with rapid resident turnover such as hostels, hotels, holiday camps and blocks of flats. 
The early stages of the bedbug (nymphs) are hard to detect with the naked eye making it hard to identify an infestation with the naked eye before biting occurs. The adult bug resembles a small brown disc, about 3.5mm long - the size of a match head. It is wingless but the legs are well developed and it can crawl up most vertical surfaces such as the bed legs. 

The elongated eggs are cemented in cracks or crevices close to the hosts (which for bedbugs are humans). The young resemble the adult and grow by moulting. Each nymph stage needs one full meal of blood before it proceeds to the next stage. Fully-grown bedbugs can endure starvation for up to a year in some cases.

Blue Bottle


Blue Bottles

The bluebottle is a large buzzing fly with shiny, metallic blue body, 6-12mm long. One bluebottle can lay up to 600 eggs, which in warm weather will hatch in less than 48 hours and produce maggots which can become fully developed in a week. These maggots burrow into meat or carrion as they feed on it, and then pupate, often in loose soil, for about ten days before emerging as adult flies from the brown pupa case. Bluebottles, like other flies, are often found on refuse tips, rotting animal matter, dirt and dustbins. They commute from filth to food and carry bacteria on their legs, feet and bodies.

Cockroach treatment

Sometimes confused with black beetles from the garden, cockroaches are distinguished by their very long whip-like antennae, flat oval bodies and rapid, jerky gait. 

The adult German cockroach is 10 to 15mm long. The common or oriental cockroach is 20 to 24mm long. They are rarely able to survive outdoors in the British climate but thrive around the heating ducts and boiler rooms of large centrally heated buildings such as hospitals, bakeries, hotel and restaurant kitchens, laundries and blocks of flats. They cluster around pipes, stoves and sinks, especially in humid areas. The German cockroach carries its egg case, a small brown purse-like capsule until the 30 or more nymphs are ready to hatch from it. The oriental cockroach deposits its 13mm long egg capsule on packaging, sacking or in suitable dark crevices before the 16 or 18 nymphs hatch.

Cockroaches grow in stages - from nymph to maturity in six to 12 months for the oriental cockroach, but only in as many weeks in the case of the German cockroach. Both species eat any sort of food and are most active after dark, from their inaccessible harbourage, to forage, contaminating food and food utensils or food preparation surfaces as they go. They taint food with an obnoxious smell and may be carriers of various diseases, including serious food poisoning.



Flea treatment Co Down

Small (2mm) wingless insects, flattened side to side, red-brown with backwardly directed spines and legs designed for jumping. All adult fleas are parasitic on warm-blooded animals. Larval stages live in the nest of the host and feed on skin, feathers and most importantly, the blood-rich faeces of the adult flea. When fully grown, the larvae spin well camouflaged silken cocoons. When fully developed, the adult waits within this until it detects the vibrations caused by a potential host. Only then does it emerge.

The complete life cycle takes about a month in the summer. Adult fleas feed on blood. Their bites can cause intense irritation around the central bright red spot. Different people react differently to a bite, both in terms of degree of reaction and time taken to react. The cat flea is by far the most common species of flea and readily bites humans. The human flea and the bird flea are next in importance. Dog fleas are rare, although other species may become temporarily attached to dogs.

Fruit Flies

Fruit Flies

A family of very small (about 3mm) flies, some with prominent red eyes, characterised by a slow hovering flight in which the abdomen hangs down. All are associated with rotting fruit and vegetables or fermenting liquids. One species breeds in sour milk, such as in the residue of forgotten milk bottles.

House Flies

House Fly

The common housefly and the lesser house fly are the most widespread household flies. The adult is 7-8mm long, grey with black stripes on the back, with a single pair of veined membranous wings. The large compound eyes take up most of the head and are wider apart in the female than the male of the species. The smaller, lesser house fly, rejoicing in the scientific name Fannia canicularis, is the one that cruises around light fittings, abruptly changing direction mid-flight. The housefly has a sticky pad on each of its six hairy feet and these enable it to walk upside down on ceilings or crawl up windows. 

Houseflies complete their life cycle of egg, maggot, pupa and adult in a week during warm weather. The eggs are laid in batches of about 120 on the rotting organic matter and the legless white maggots burrow into this food until ready to pupate in loose soil or rubbish. Houseflies may transmit a wide range of bacterial diseases.

The house mouse and sometimes the long-tailed field mouse seek the warmth and shelter of buildings for nesting sites and food. Their presence is usually detected from their dark-coloured droppings or damage to stored foods in the larder, packaging or woodwork.

Mice become sexually mature in eight to ten weeks and a pair may produce eight litters, each of 16 young, in a year. Multiply those and you arrive at a horrifying number of mice! They climb well and can squeeze through very small gaps. These nibbling creatures have a compulsive need to gnaw in order to keep their incisor teeth worn down to a constant length. Electric cables, water and gas pipes, packaging and woodwork may all be seriously damaged by mice - many instances of electrical fires and floods have been attributed to them. They contaminate far more food than they consume and they are capable of carrying many diseases, particularly food poisoning. The average mouse deposits 70 droppings in 24 hours and urinates frequently to mark its territory.

Mice are erratic, sporadic feeders, nibbling at many sources of food rather than taking repeated meals from any one item. They do not need free water to drink as they normally obtain sufficient moisture from their food.

The rat has plagued humans for thousands of years - the rat flea was responsible for the Black Death. There are two species of rat in Britain, Rattus norvegicus which is commonly known as the brown rat and Rattus rattus, which is commonly called the black rat or ship rat. 
The brown rat is the larger of the two, often weighing over half a kilo and measuring about 23cm, without counting the tail. It has a blunt muzzle, small hair-covered ears and a tail that is shorter than its body length. The black rat weighs only half as much and is slightly shorter. It has a pointed muzzle, large, almost hairless ears, a more slender body and a long thin tail that is longer than its body.
The brown rat is the commoner species and stays near ground level. The black rat still appears in seaport towns and is a more agile climber, often entering the upper floors of buildings. It is possible to identify the species present from the different shaped droppings, footprints in the dust (the brown rat is flat footed, the black rat runs on its toes) and the presence of tail swipes. In towns, brown rats often live in sewers but in the countryside, there is a constant background population in fields and hedges.
Both species breed rapidly and become sexually mature in about three months. Each female may produce from three to twelve litters of between six and eight young in a year. Brown rats will burrow underground or into suitably soft materials to make a nest. Refuse tips, loose soil under sheds and earth banks are all likely sites and chewed paper, straw or insulation material may be incorporated as nest material. The young are born blind, helpless and naked and depend on their mother for food for about three weeks before they are sufficiently developed to take solid food.
Rats, like mice, need to gnaw to keep their constantly growing incisor teeth worn down. They damage woodwork, plastic and lead pipes and will sometimes strip insulation from electrical cables by their gnawing. Rats will hoard food for future consumption and numerous cases of theft have been found to be the work of rats. They feed mostly at night and an average rat eats 50g of food a day. Creatures of habit, rats leave regular runs to and from feeding areas. They can be a menace to poultry, eating eggs, chicks and animal feed.
They are also capable of spreading many diseases from their filthy surroundings in sewers or refuse tips and can transmit food poisoning, Weil’s disease (from which about ten people and a number of dogs die each year in the UK), murine typhus, rat bite fever, trichinosis and other diseases. They are probable carriers of foot and mouth disease on farms. They contaminate more food than they consume and their urine can pollute stagnant water.

Large, conspicuous buzzing insects with yellow and black striped, wasp-waisted bodies, 10-15mm long. They have a sweet tooth at one end and a painful sting at the other. The queen wasp is larger (20mm) and she hibernates during winter, making a nest in the spring to lay her eggs. She feeds the grubs on insects until they develop into worker wasps, three to four weeks later. Workers, all sterile females, forage for over a mile in search of food. One nest may produce 30,000 wasps in a year.

At their peak in August and September, with the youngsters reared, the workers turn to the sweet food they prefer and become a nuisance wherever this is available. If annoyed or threatened, wasps will sting and the best remedy - after removing the sting with a clean finger nail, is to apply anti-histamine. Some people react violently to being stung with several dying each year.
