Carpet Bugs – The Varied Carpet Beetle

Carpet Bugs – The Varied Carpet Beetle – The Varied Carpet Beetle (Anthrenus verbasci) is a recent newcomer to the north of England . having been largely found mainly in more southern counties but now pest controllers in Cheshire, Manchester and Lancashire are increasingly having to deal with this pest.

It is a very distinctive, easily recognised beetle that can be a serious problem in the household. It feeds on natural fibres and can damage anything of natural origin, woolen carpets, furniture and clothing.
The larval form is known as a woolly bear, a name it shares with the larvae of Pyrrharctia isabella or the Isabella Tiger moth.

A verbasci was the very first insect to be demonstrated to have a circadian and an annual cycle and to date remains a classic example of circannual cycles in insects.
The larval form of A. verbasci are roughly 4-5 mm in length. The body is covered in a pattern of alternating light- and dark-brown stripes. The body is usually wider at the back than at the front and also bears 3 pairs of hair tufts along its rear abdomen that can be used for self-defence

These can also cause problems for human beings as when they become embedded in human skin they can cause a reaction similar to a flea or bed bug bite so when checking for the possible presence of biting insects pest controllers also need to be on the lookout for larval casts of the carpet beetle.

Adult A. verbasci range from 1.7 to 3.5 mm in length. Their dorsal surface has scales of two colours, whitish and yellowish-brown. White scales are condensed along the lateral margins of the pronotum. In addition, their antennae are 11-segmented with a club of 3 segments
The varied carpet beetle has a very unusual life cycle for an insect, developing from larvae to adult in 1-3 years, depending on the environment in which it finds itself.

Larvae hatch from eggs in the spring, often they are associated with birds’  nests or around stored natural fabrics Larvae feed on natural fibres throughout their development, eventually experiencing a dormancy or diapause before completing pupation and emerging as an adult. Adults emerge between late March and early August, and feeding on pollen.

These pests cause both physical damage by their larvae eating fabrics and psychological trauma from the vast numbers of these pests which can emerge into living quarters.
When dealing with these pests it is important to check for the presence of birds’ nesting material and remove any nests and feathers etc from the affected area before treating the affected area.

It is important to note that in the U.K legislation affects the removal of birds’ nest, including sparrows and starlings which are the two common birds which have an association with A.verbasci so professional help should be sought to avoid falling foul of the law.

 Pest Control In Manchester & Other Large Cities by Ken Chadwick 

Big city pest control brings its own set of special circumstances which sometimes require a different approach to smaller and quieter towns.

Firstly the very logistics of working in a busy big city can be problematic, even the basics of parking your van near the customers’ premises can be difficult especially when equipment needs to be carried. This can lead to increased charges which have to be passed onto the customer and sometimes these can be substantial. 

Premises are often open seven days a week and even twenty-four hours a day thus leaving little opportunity for the pest controller to go about his work. 

This may not cause too much difficulty in routine preventative inspection visits but can cause extreme problems when infestation is detected in that often pesticides require premises to be vacated for a period of time.

 Big towns & cities usually have a large number of takeaways providing food to eat on the go and often will be littered overnight with uneaten food scraps providing food for rats, pigeons and seagulls which have now moved inland. 

Often daily waste collections mean that bagged food waste is put outside overnight thus encouraging rodents. 

Pigeons & Seagulls are obviously a nuisance with their noise and fouling but often will take food stuffs up onto roofs and ledges causing a build up of rotten materials which produce flies and maggots. 

Pigeons will often roost and nest in roof spaces for many years leading to a large build up of pigeon guano and often their droppings can make the walkways below slippery and dangerous.  

Most big cities have a varied ethnic mix with a variety of shops and restaurants supplying foods from all over the world. Often these foods are imported in bulk from countries where pests such as cockroaches are endemic and these pests are then brought into the U.K. hidden away in the goods and packaging. 

Perhaps the most difficult aspect of big city pest control is the resurgence of the bed bug which in recent years has seen numbers rise exponentially. 

A high transient population of visitors often staying in inexpensive, high turnover accommodation means that the bugs can spread quickly throughout a city and even expensive upmarket establishments are not exempt. 

The very nature of a bed bug infestation means that it is difficult and expensive to cure and news of infestation is often of interest to local press who will often carry a story about a guest being bitten, thus ruining the reputation of the establishment. 

Bed bug infestations require that the infested bedroom and those adjacent be treated thus losing revenue for the establishment.
