Other Pests.


Biscuit Beetles
Found in shops and domestic larders, Biscuit Beetles are a pest of cereal products including flour, bread, breakfast cereals and spices.

Carpet Beetles
A major textile pest, Carpet Beetles are commonly found on carpets, skirting boards and in wardrobes. Larval forms can cause damage to any products containing Keratin, including wool, fur, leather, silk and dried animal remains. Some infestations can be traced to bird or rodent nests but they can also enter homes looking for food and places to hibernate.

Hide and Larder Beetles
Dermestid (skin feeding) Beetles commonly infest items with a high protein content such as skins, feathers, bones, dried meat, fish meal and dog biscuits. In domestic properties, they are often associated with poor hygiene and housekeeping where food has been left out or spilled on the floor. Hairs from the larval form may cause skin irritation.

Control of Beetles can be achieved by identifying and removing the source of the infestation, thorough housekeeping including vacuuming of infested areas and treatment with residual insecticides.


Poultry Mites
Poultry mites are a particular problem in poultry units but are often found in birds nests. When the chicks are in the nest the population will increase. When the birds leave the nest the mites no longer have a food supply (blood) and will find their way into buildings and attack the first warm blooded host it finds (often humans).

Storage Mites
Storage mites are many and varied. They occur frequently in grain stores, animal feed, flour mills, and cheese stores. They are also a pest in the confectionary industry infesting sweet factories and bakeries. Products contaminated by mites will be rendered unusable.

House Dust Mite
The house dust mite has been implicated in causing dermatitis, rhinitis, respiratory tract irratation and intestinal upsets. They are also implicated in the cause of asthma. House dust mites feed on skin scales which are constantly shed from the human body and accumulate in beds and furniture.

Control is achieved by a combination of reducing humidity, treatment with an acaricide and in the case of house dust mites, extensive vacuuming and cleaning.


There are many varieties of stored product moths including the Clothes Moth, Warehouse Moth, Rice Moth, Flour Moth and Indian Meal Moth. A major pest of stored products and commodities, moth larvae can cause considerable damage to textiles, grain, cereals, nuts, dried fruit, chocolate and tobacco. In addition to the damage caused by feeding, moth larvae can contaminate products with webbing and frass (droppings) and can even lead to blocked machinery and ducting.


As with many pests, prevention is preferable to control. This can be achieved by using a variety of traps and lures to monitor moth levels and provide early warning of a potential moth infestation. Control can be achieved by integrating insecticidal treatments with good hygiene.


Psocids, or 'Booklice' are small soft-bodied insects found in warehouses, food manufacturing premises, granaries and museums, as well as domestic and retail premises. They infest organic matter such as stored food, plaster, leather, woodwork and paper/books. In domestic premises they are often found infesting damp surfaces, such as bathrooms and newly plastered walls.

Control is achieved using residual insecticides and by insuring that infested areas and thoroughly aired and dry. Use of a dehumidifier may be of some benefit.


Often recognized by their snout-like 'rostrum', Weevils are a serious pest of grains and cereals. Primarily pests of stored gain (e.g. on farms), Weevils can also infest warehouses, commercial kitchens and domestic properties where they feed on grains, cereals and pasta. In commercial kitchens and domestic properties, Weevils are often introduced on infested products or packaging.

Weevil levels can be monitored using traps and lures and stored grain can be protected using special grain protectant chemicals. In kitchens and domestic properties, control is achieved by removal of infested items and treatment with a residual insecticide.
