Pest Identification > Rodents | Mammals | Insects | Birds


There are probably more insects in this world than any other group of creatures, however only a few of them are considered pests. Only some of the more common ones are listed here. Insects, although these creatures are an important and extremely necessary part of our ecology they can become pests. They can spread and carry diseases, damage property and possessions, contaminate and cross contaminate stored foods and they can bite, sting and cause allergies. If you think you have an infestation then give us a call.




Foraging ants are usually found in are gardens, sometimes they enter our properties and can prove to be a nuisance. They do not usually cause any health risk. They help to control aphids in gardens. In late summer winged males and larger winged female leave the nest in great numbers to start new colonies, but only a tiny amount actually survive. 3-5 mm in length they take 3 weeks to fully develop. Their life cycle is one of complete metamorphosis, EGG, LARVA, PUPA, ADULT. The eggs are laid by a queen.


PHARAOHS ANT (Monomorium pharaonis)


The Pharaohs ant is tiny 2mm in length of tropical origin. They like a warm climate so in Briton they are an indoor species, often associated with hospitals, prisons and blocks of flats. Most often found in locations with a source of moisture such as kitchens and bathrooms. The colonies are capable of producing multiple queens which satellite out when the nest is attacked. Professional treatment is highly recommended.


BED BUGS (Cimex Lectularius)


Adults are a reddish brown in colour and 4-5mm in length, 1.5-3mm width. Adults can lay 200-500 eggs at 21 degrees Celsius which can take between 6-17 days to hatch; their life cycle is incomplete metamorphosis, EGG, NYMPH, ADULT. They are nocturnal and during daylight hide in cracks, crevices, mattresses and furniture. Adults can survive 12 months without feeding. They inject saliva when feeding that causes an allergic reaction swelling, itching and burning reactions are common.


GERMAN COCKROACH (Blatella germanica)

Adults grow to about 17mm in length light brown in colour with darker head shield. They have an Incomplete metamorphosis life cycle EGG, NYMPH, ADULT. Nymphs are wingless and can be much darker than the adult. Egg cases are carried by the female until just before hatching; each egg case can hold 20-30 eggs which take 28-30 days to hatch. Females live for around 200 days, slightly longer than the males. The German cockroach is an excellent climber and this should be considered when treating, they are mainly nocturnal and like to hide in any crack or crevice. They can spread diseases and cross contaminate.


ORIENTAL COCKROACH (Blatta orientalis)


Larger and darker than the German cockroach, the Oriental cockroach is dark reddish brown and up to 25mm in length unlike others in this genus the Oriental cockroach cannot climb smooth surfaces, they prefer moist conditions and can survive colder temperatures. Can be found in basements and unventilated areas such as ducting as well as cracks and crevices. Adults can live for 1 year and can produce an average of 150 young. Life cycle is incomplete metamorphosis, EGG, NYMPH, and ADULT.


CAT AND DOG FLEA (Ctenocephalides spp)


Adults are 2-3mm in length and shiny brown in colour. 4-8 eggs are laid after each blood feed, a single female can lay between 800-1000 eggs in her lifetime which might be 2 years. The larvae love dark humid places and thrive in pet bedding and carpet edges. A Cats bedding can support a flea population of 8000 immature and 2000 adults. Flea bites cause allergic reactions swelling, itching and burning. Life cycle is complete metamorphosis EGG, LARVEA, PUPA, ADULT.


COMMON CLOTHES MOTH (Tineola bisselliella)


Clothes Moths are 7mm in length and yellowish brown which can look metallic. Clothes moths rarely fly towards light in the dark preferring the darkness. They like to hide in closets, wardrobes and chests of draws, where eggs will be laid in folds of clothing and materials, the larvae will only eat natural fibres such as wool or silk. A female can lay 100-150 eggs which will hatch in 5 days as larvae, another 6 weeks to maturity. Adults do not eat materials. Life cycle is complete metamorphosis EGG, LARVAE, PUPA, and ADULT.


COMMON HOUSE FLY (Musca domestica)


Very common the world over, 10mm in length 6mm wide. Breed on rotting vegetable matter or animal faeces. Complete metamorphosis life cycle EGG, LARVAE, NYMPH and ADULT. Flies are highly mobile and cause disease transmission, food spoilage and nuisance. May be a severe problem in animal units and refuse tips


WASP (Vespula vulgaris)

Wasps are found in lofts, cavity walls, soil banks and trees. Nest is made of paper (chewed wood) and can become very large. Colonies only survive for one season (one year). Wasp are between 10-20mm in length and have a complete metamorphosis life cycle EGG, LARVAE, NYMPH and ADULT. Many thousands of eggs will be laid by the queen in spring and summer at the end of summer she will die. New queens will leave the nest in autumn and overwinter in small golf ball sized nests, from which a new colony will grow in spring. Wasp can give a painful sting.
