Bed bugs are increasing in hotels throughout England, and mice, rats, flies and cockroaches pose a threat to hygiene standards in food preparation and storage because of their disease risk. We monitor and survey premises and, if problems occur, we deal with them efficiently and discreetly. For free advice, or to arrange a free site survey, please call: 0345 600 6400.

Preventing pest problems in offices and warehouses
Pests in and around offices/warehouse can cause great distress for those that work in them. They can also damage buildings, fittings and stock, with computer equipment and cables being particularly at risk from gnawing.

There are a number of factors that contribute to the risk of pest problems in commercial properties, such as the location, age and condition of the building, as well as the kind of goods stored in or around the building and whether food is served on site.

We can survey your premises and if there is problem we will deal with it efficiently and discreetly. A pest control service contract may prove more cost effective. For free advice, to discuss a contract or arrange a free survey, please call us on 0345 600 6400.

Agricultural businesses
Rats, mice and moles are the most common pest type for farmers and can cause extensive damage to both crops and buildings. We offer a free site survey and advice, as well as tailored pest control treatments to suit your needs.

We can survey your premises and if there is problem we will deal with it efficiently and discreetly. A pest control service contract may prove more cost effective. For free advice, to discuss a contract or arrange a free survey, please call us on 0345 600 6400.

Identifying your pest

Welcome to our pest gallery. This should help you quickly identify the most common pests in your area, and how to prevent them appearing.

Please note, we do not carry out treatment for bees of any kind. You may require professional assistance when dealing with pests.

We do not carry out pest treatments for:
Bats, bees, slugs, snails, spiders, pigeons, rabbits, squirrels, foxes or woodworm.
Seasonal pests
During May to September, wasps are extremely active. Their nests can be found in sheds, lofts, airbricks and bushes. If the nests are high up, in most cases they can be left and will die naturally at the end of the season.

However, as the season draws to an end, the combination of the cool weather and a diet of fermenting fruit juices make them irritable and more likely to sting.
Wasps or bees?
If you are unsure if you have a wasp or bees’ nest, please click here before booking.
Wasps (Vespula Vulgaris)
Wasps (Vespula Vulgaris)There are several species of wasp found in the UK, all similar in appearance. Wasps are bright yellow and black and roughly 10 to 20mm in length. Wasps have a very slim waist and are a lot less hairy than bees. Not to be mistaken with hornets, they are somewhat larger and brown and yellow in colour. Harmless mortar bees are often mistaken for wasps.

Living environments
Young, fertilised queens survive the winter by hibernating, then emerging in mid-April to find a suitable site for nests. Common sites are loft spaces, cavity walls and sheds. Once found, she builds the first cell using chewed wood pulp and lays between 10 and 20 eggs, then feeds the resulting larvae until they emerge as workers. These workers then take over the tasks of enlarging the nest and providing food for larvae.

The nest may potentially grow to the size of a football and house about 5,000 wasps but, in some cases, can be larger. In late summer, a generation of males and young queens emerge to mate, but the other wasps will gradually die off as the weather cools. The nest will not be used again.

Preventative steps or treatments you can do yourself
There are products available to kill a nest but please ensure you follow instructions carefully, taking all necessary precautions. Consider the risk of being stung. While for most it can be a painful annoyance, there is a minority of people who are allergic and can suffer extreme reactions. If you can, treat a nest early/late in the day when it is cooler. It’s most likely all adults have returned to the nest and are much less active. 
 
Ants (Lasius Niger)
Description: Click here to find out more about antsBlack ants are common in all parts of the UK and usually nest outdoors, favouring sandy or dry soils near house foundations and under paths. They are also increasingly found in cavity walls of properties. Worker ants are usually a dark brown-black color, while queens are mid-brown and roughly 15mm long.

Living environments
Worker ants invade buildings while foraging for food, particularly sweet foods. They enter through tiny crevices under kitchen units, skirting boards or anywhere there is a gap big enough. When an ant finds a food source, other ants will soon gather, sometimes in large numbers.

During late summer, flying male and queen ants can be seen swarming. They mate on the wing and can swarm for a few hours. They can be dealt with immediately using a suitable flying insect spray and can be also vacuumed, if occurring indoors.

Preventative steps or treatments you can do yourself
If the nest can be located, it can be destroyed using an ant powder or spray, available at most garden centres. Powders should be used outdoors in cracks, crevices, airbricks and other entry points to create a barrier. Water-based sprays can be used indoors.

Ant gels and liquids are also available. These are poisons with a sweet base to trick the ant into feeding and carry the bait back to the nest. However, treatment must be continuous for several weeks and sprays & powders should not be used in conjunction with these products, as you will simply kill the ant and not the nest.
Rats (Rattus Norvegicus)
Description: Click here to find out more about ratsThe common rat is usually around 20 to 27cm long and weighs about 100-500g. They are commonly a brownish grey, with grey underneath. However, the colour varies. Rats have a single pair of upper and lower incisor teeth that continuously grow. This is why they gnaw, to prevent their incisors from growing too long and preventing them from eating.

Living environments
Rats generally stay within 50m of their home, but can range up to 300m. They can move every two weeks or so, depending on food sources, and may travel several kilometres to seek food. They are mainly active at night and can be found in fields, gardens and sewers. Rats are sexually mature at three to four months old and produce six to 11 young.

Preventative steps or treatments you can do yourself
  • Compost bins should be placed on solid bases to prevent rats from burrowing.
  • Keep overhanging branches trim, away from roofs to prevent rats from accessing loft spaces.
  • Check sheds for holes in the floor and back panels where rats may have gnawed through during winter. Keep these sealed to prevent access.
  • Check for holes around the outside of the house, particularly around waste pipes. Remember, a rat can get through holes as small as 25mm.
If you see a rat in your garden and you feed birds, stop immediately, as this will encourage rats into your garden.
Mice (Mus Domesticus)
Description: Click here to find out more about miceAn average house mouse is roughly six to 9cm long, with a tail of roughly eight to 10cm long. Their fur is a brownish grey, but can be lighter and they have excellent hearing due to their large ears. Mice reach sexual maturity 42 days after birth, so it is imperative to deal with mouse activity as quickly as possible. Their life cycle is roughly nine to 12 months and the reproduce roughly eight times per year, with a litter size of five to six offspring.

Living environments
Mice build nests in hard to find spaces, such as under floorboards, in wall cavities and in loft spaces. They are very inquisitive and like warmth, so check airing cupboards and behind cookers/fridges for signs of activity, such as droppings. They do not have the ability to control their bladder and constantly dribble urine that can contaminate food.

Preventative steps or treatments you can do yourself
If you see a mouse in your garden and you feed birds, stop immediately, as this will encourage mice into your garden. 

It is possible for a young mouse to get through a gap as small as 6mm (if you can get a ballpoint pen through the gap a mouse can get in) so it’s a good idea to check around waste pipes that go through the wall such as those from the sink, and washing machine and seal any gaps.
 
The most common entry point for mice to enter a property is under a garage door and this should be the first place to look for signs of droppings. During winter months, so you may wish to lay a trap here first.
Bed bugs (Cimex Lectularis)
Description: Click here to find out more about bed bugsThe adult bed bug is a flat, oval insect 5mm by 3mm and is reddish brown in colour. The female bed bug lays pearly white eggs approximately 1mm long. These are ‘glued’ into cracks and crevices in bed frames, furniture, wallpaper and anywhere that provides dark harbourage during daylight. They lay roughly 150 eggs that hatch within 10 to 20 days and reach adulthood in approximately nine weeks under reasonable conditions. This takes longer if the temperature is low. Adults live for up to 18 months, usually feeding weekly, but can survive for more than a year without blood.

Living environments
Bed bugs do not fly, so they must crawl or be transported via clothing, luggage, or anything they can harbour in. They feed on blood, but can survive for long periods without feeding. While they are usually associated with poor, overcrowded and unhygienic conditions, they can be transported onto any premises. In domestic cases, most infestations are found in bedrooms, with hiding places being close to where the host sleeps – bed frames, mattresses etc. Bed bugs bite and feed on blood, which can cause severe irritation to some people. However, they are not known to carry disease unless, that is, you regard insomnia as such. 

Preventative steps or treatments you can do yourself
Check your bed, or any bed you sleep in, for tiny blood droplets on sheets and mattresses. Move the bed away from the wall and check behind the headboard and mattress for any signs.
 
Cockroaches
Description: Click here to find out more about cockroachesCockroaches are large insects that range in size from 10 to 23mm with long antennae and two pairs of wings. The German cockroach is dark brown and smaller than the Oriental cockroach, which is black in colour. The German variety can climb smooth surfaces. The female cockroach produces up to eight purse-like egg cases monthly. These can contain up to 30 eggs and nymphs hatch within two to four weeks (six to 12 for Oriental cockroaches). Their eggs are the size and shape of a small kidney bean and brown in colour. Their faeces looks like black pepper.

Living environments
Cockroaches can carry food germs and are responsible for the spread of diseases such as dysentery and gastro-enteritis and they will feed on almost anything, including faecal matter. Food contamination occurs when the insect comes into contact with food, food preparation surfaces or through faecal contamination of food. They will spend their days hiding in cracks and crevices in a building, becoming more active at night. If a light is switched on they will scamper away to hide.

Preventative steps or treatments you can do yourself
You can prevent infestations by making sure your premises are clean and there are no food sources or hiding places. Plug all small cracks with latex or silicone sealant. Larger holes will need to be patched. Move debris, firewood and rubbish away from the house and out of kitchens.
 
Fleas (Ctenocephalides)
Description: Click here to find out more about fleasThe threadlike larvae (1.5mm) hatch in approximately a week and thrive in dark, humid places. After two to three weeks, they moult twice and grow to 5mm long and spin their cocoons for pupation.

Fleas formed in cocoons may ‘overwinter’, but emerge by the stimulation of vibration, usually of the host. This is why attacks sometimes take place when a property has been left empty. In favourable conditions, the life cycle is normally complete in four weeks. Fleas can only lay eggs after taking blood from a host animal.

Living environments
Adult fleas live exclusively as parasites of warm-blooded animals, like cats and dogs. Cat fleas are responsible for 75% of all flea infestations. Cat and dog fleas will feed from humans when there are no animals around, but this is not their first choice. Flea eggs are 0.5mm long, pearly white, oval and slightly sticky, generally found on the hair, bedding or clothing of the host.

You may have fleas and not have an animal
  • during summer, fleas can survive outside and be carried indoors
  • visitors may have animals and transport fleas
  • you can visit people with animals and transport fleas
  • moving into a property, you could inherit a flea problem
Preventative steps or treatments you can do yourself
If a flea treatment is carried out, the floors of your property will be covered by a layer of insecticide that will dry to a very fine powder that is odourless and invisible. It has a very good residual effect and will continue to work for some time, if left undisturbed. Adult fleas will be killed within a few days, but the floor should not be vacuumed, swept or washed for seven to 10 days post treatment, as there will still be eggs continuing to hatch. This is normal and provided the insecticide remains in place, adults will be killed as they emerge. If you have pets at the premises, they should also be treated for fleas without delay using a veterinary recommended treatment. For further information, please consult your vet.

Causes of re-infestation
  • vacuuming before the seven to 10 day period
  • bringing more fleas from other premises
  • not treating your pet or not following the product’s instructions 
Moles (Talpa Europaea)
Description: Click here to find out more about molesThe European mole is between four to six-and-a-half inches long with a tiny tail of three quarters of an inch. It weighs three to five ounces and has small eyes and ears. Moles are practically blind and have poor hearing, but make up for it with their excellent sense of smell.

Their fur is short, dense and black and can lie at any angle, meaning it can go backwards and forwards through its tunnels. A mole’s diet primarily consists of earthworms and other small invertebrates found in soil, as well as a variety of nuts.

The mole runs are, in reality, worm traps as the mole, when sensing a worm fall into the tunnel, quickly runs along to kill and eat it. Their saliva contains a toxin that can paralyze earthworms, so they can store their prey for later consumption.

Living environments
Moles are solitary creatures and spend the majority of their life spans alone. Usually, they only associate with others during mating, or when a mother raises her young. They live underground and their main home consists of a single central chamber, with many connected tunnels.

Preventative steps or treatments you can do yourself
Various over the counter products can be obtained, but are limited to their success rate.
 
Booklice (Psocids Liposcelis Bostrychophilus)
Photo of Booklice (Psocids Liposcelis Bostrychophilus)Booklice are soft bodied insects, yellowish brown in colour and rarely exceed one to 2mm in length. Some species have two membranous wings, although in many species the wings aren’t present. While they are common, they are harmless and do not cause any damage or destruction.

Living environments
Occasionally, especially during autumn, people find their food cupboards have become infested by booklice. They are often discovered in flour, milk powder, sugar or any dried food. They dislike light and are found in folds in packaging and cracks and crevices in cupboards.

Preventative steps or treatments you can do yourself
Infestations are not caused by poor hygiene and are as common in new homes, as they are in older properties. If you find booklice in your kitchen, do not use insecticides, as you risk food contamination. The best method of eradication is to remove and dispose of all affected food.

Clean cupboards with a dry cloth, or vacuum them and empty contents into a dustbin kept outside. Ensure the storage area is dry before restocking. Keep cupboards ventilated and dry and check them regularly. Check use by dates and food upon first opening to be sure there is no infestation. 
Woodlice (Order Isopoda)
Woodlice (Order Isopoda)Although they look like insects, woodlice are in fact crustaceans related to crabs and lobsters. It is thought there are roughly 3,500 species of woodlice worldwide, with 35 to 40 being found in the British Isles. Woodlice are sometimes called pill bugs and slaters and the pill woodlouse gets its name because it can roll up into a ball. Common woodlice live for three to four years and their main predators are centipedes, toads, shrews and spiders.

Living environments
Most woodlice are found on land, but their ancestors used to live in water. This is why they still breathe through gills. Woodlice eat rotting plants, fungi and their own faeces. They expel waste by producing ammonia, which passes through as gas. After mating, females carry their fertilised eggs in a small pouch under their bodies. When the young hatch, they stay in the pouch until they are big enough to survive alone.

Preventative steps or treatments you can do yourself
Woodlice are harmless to man, as they do not bite, so treatment is rarely necessary. If treatment is required, then the application of a suitable insect powder should be affective. These can be purchased at most garden centres and DIY stores.
 
Silverfish (Lespisma Saccharina)
A Silverfish (Lespisma Saccharina)Silverfish grow to about 12mm in length and, as the name implies, are silver-coloured and glisten. The female silverfish is believed to lay about 100 eggs, either single or in groups in crevices or cracks and are ‘glued’ to the surface as they are laid. They are small and white, but soon turn brown.

Hatch time varies from two to eight weeks, depending on the temperature and humidity of the breeding site. Newly hatched, they are about 2mm long and the time they take to reach maturity varies from a few months to over a year, depending on their surroundings.

Living environments
Silverfish are found in moist areas such as kitchens, bathrooms and basements. They can also be found in books and paper, slightly damp cupboards, behind skirting boards and loose wallpaper. They are nocturnal and move very rapidly when disturbed. They feed mainly on small food particles and the paste on the back of wallpaper. They attack gums and glues of bookbinding, feeds on fragments of dead insects and may also eat textiles.

The presence of silverfish is an indication of damp conditions. This may be a warning that repairs are needed. Another common problem is condensation, sometimes caused by drying washing indoors, or by cooking.

Preventative steps or treatments you can do yourself
When only a few silverfish are seen, it is not necessary to take any action other than checking for damp. If large numbers trouble you, they are easily controlled with regular insect spray or dust that can be bought from garden centres.
Wharf Borer (Nacerdes Melanura)
Description: Wharf BorerAdult wharf borers are narrow, flattened insects approximately 1cm long. When viewed from above, the main body varies from brown to a rusty colour, covered in very fine yellow hairs. The tips of the wings are generally black, along with the eyes, legs and underside.

The antennae of the adult are about half as long as the length of the body. Mature larvae are two to three times longer than the adults and are a light brown to cream colour covered in very fine brown hairs. The mandibles of the larvae are dark brown.

Larvae have three sets of long legs located on the thorax and two leg-like appendages on the third and fourth abdominal segments. The life cycle of a wharf borer from egg to adult usually takes about one year, although in cooler locales this may take longer.

Living environments
Wharf borers are found throughout much of the United States and Canada and have been introduced to Europe, presumably through commerce. Because they are found in moist wood, they are mainly associated with coastal areas, lakes, rivers, estuaries and waterways. They have been found in diverse places such as wharf timbers, crawlspaces or any wood with high moisture content, subject to decay. Adults are usually noticed as they emerge from wood and this can take place at any time, but are most commonly found in spring and summer. Females deposit eggs and the larvae tunnel into wood, growing and producing long, elaborate tunnels.

Preventative steps or treatments you can do yourself
Wharf borers are a nuisance pest and generally complete their life cycle in structurally unsound wood. However, in situations where the adult population is large enough to pose a problem, the best control strategy would be to correct any existing wood moisture problems and removing any structurally unsound or infested wood. If necessary, wood should always be replaced with wood treated by a preservative or a material that is not susceptible to insect attack.

They are harmless to man, so treatment is rarely necessary. However, the application of a suitable insect spray or powder should prove affective.
