Case Studies

The problem

Parakeets have been causing havoc in a large development of flats above the main shopping district in Feltham, Middlesex.

After resident had complained about noises above their bathroom ceiling. Cleankill Pest Control received an enquiry from the site manager and carried out an inspection.

Ring-neck and Monk parakeet numbers have increased in recent years and are successfully living wild in London and the South East. Classified as agricultural and horticultural pests by Natural England in 2010, these birds do still enjoy the legal protection afforded wild birds despite becoming a menace in some places.

The solution

Raised flooring in office buildings - designed to create space for ducting and cables - provides the perfect space for mice. They can move around the building without being seen and then emerge through openings such as risers used to house electrical sockets.

Cleankill responded to a call from a customer with offices near London Bridge after staff saw mice running around on the carpet.

To help establish the extent of the infestation, a motion-sensitive camera was placed under the floor near one of the risers for two and a half days.

Cleankill Director Clive Bury explains: “We needed to find out whether it was a random problem or an on-going infestation. The floor area was extensive – around 400 square metres – so we chose two locations for the cameras.”

A rat trying to hide

Make sure your building is well maintained and drain pipes are capped off is the warning from Cleankill Environmental Services to London premises managers.

The managers of a commercial office building in Holborn, London, called in Cleankill after staff complained of noises coming from behind a wall.

Cleankill technicians were horrified to find a large colony of rats was coming in and out of the building through an uncovered drain that led directly into the London sewer network. If the problem had been left any longer the rats could have entered the building in large numbers and caused extensive damage to cables and pipes as well as contaminating everything they touched.

Filter Flies in London

Many office blocks in London have restaurants and shops on the ground floor which can present additional challenges to FMs if tenants do not take steps to keep their areas hygienic and pest free.

This was the case with an upmarket Italian restaurant in central London. Cleankill was called to deal with a serious fly infestation which was spreading through a void into the toilets and then into the eating areas. They were identified as filter flies – small flies about the size of fruit flies – commonly found at sewage farms which provide the ideal breeding conditions.

Bed bug

When Cleankill was called to a bed bug problem in South Kensington, London, technicians found one of the worst infestations they had ever encountered.

The building they were called to was made up of bedsits which all had sitting tenants. One of the bedsits (an area of approximately 14 feet by 16 feet) was occupied by a man in his mid-70s who lived in one room with his bed, wardrobe and armchair – all of which were heavily infested.

Cleankill technicians believe that the bed bugs had been in residence and spreading around the bedsit for several months. The tenant eventually reported the problem, when he had had enough, to his landlord who called Cleankill for help.

When it comes to conserving heritage, Cleankill has the knowledge, expertise and equipment to treat historic artefacts carefully, sensitively and effectively. So we were delighted to help the Bluebell Railway team when they called us to solve a serious infestation of Common Clothes Moth (Tineola bisselliella).

After allowing a major pest control company a year to sort out a mouse problem, the final straw came for a department store when a creature jumped from a suit pocket in front of a customer.

Part of the problem was the building’s construction: six floors of suspended ceilings – perfect hiding places for mice and other rodents - and a large number of cupboards stacked high with stock. Mice were living and breeding in the ceilings and cupboards unnoticed.

At night mice would run riot and in the morning staff would find trails of droppings around the store, including the restaurant and food preparation areas. Mice were also living in redundant equipment.

One of Cleankill’s more unusual pest control contracts involved delivering an industrial freezer to a clothing warehouse which was infested with clothes moths. The clothing retailer discovered a clothes moth problem in the warehouse where the company stores samples of its clothing ranges from previous years, when the samples were found to be damaged. Urgent action was needed to stop any further damage. The retailer called Cleankill to solve the problem.

Spraying the clothes with chemicals was not an option and Cleankill had to quickly devise a solution that would stop the problem as quickly as possible and prevent any further damage.

Cleankill was proud to be in charge of the pest control at two high-profile sites during London 2012.

At the equestrian site in Greenwich, Cleankill looked after the pest control at all of the food areas, including the concessions, marquees and all the kitchens – including the ones for the athletes.

The pests that were of particular concern and needed prevention measures in place included mice, rats and garden ants. Bait stations were installed and sticky pad insect detectors placed in appropriate locations. Visits were carried out by technicians every ten days in the run up to the games and during the Olympics.

Cleankill was also called in to provide pest control services for the food areas at Eton Dorney – the Olympic venue for rowing.

The Cleankill team was called in to solve a serious bed bug problem in one of the largest blocks of flats in London. 

Thirty out of 600 flats in the block in South London had been infected and it was a case of finding the source of the problem before treatment could start.

Cleankill staff searched the flats and found an extremely serious infestation in the very last one they checked.

Sales Manager Mike Williamson said: “It was absolutely horrendous. The man who occupied the flat had literally become immune to the bed bugs and the bites and was living side-by-side with them. It was the worse infestation I’ve seen in 15 years and the problems in the other flats were linked to this one particular flat which was the hub.”
