Flea Treatments & Control

Most people have experienced a fleabite in their lifetime, as fleas invade any home regardless of how clean you keep your house. It is a common myth that fleas infest untidy homes, as this is simply not true. Please do not feel embarrassed if you have a flea infestation as it’s very easy to pick up an infestation as they can enter your home on guests, pets and many other ways. Once they are in the home they are very difficult to eliminate with DIY products due to the longevity of the flea life cycle. The flea life cycle progresses from egg to larva then pupa and finally an adult (known as complete metamorphosis). This life cycle can be completed if the conditions are warm and there is the presence of a suitable host which can be an animal but also humans. The life cycle can take approximately one month, using the cat flea Ctenocephalides felis as a guide. The pupal stage is significant because fleas can survive for several months in the absence of a host and in cool conditions before emerging when someone or something enters the undisturbed area again. This is common when entering a vacant rental property or empty property and a flea outbreak occurs although there is nothing present. Control of fleas in vacant properties can be challenging with typical treatments because a large portion of the flea population is still in the pupal stage which is encased within a silk outer layer which repels water. By the time you realize you have fleas they have already laid eggs around your home. There is normally a spike in activity during the months of August, through September and October. Fleas are attracted to heat vibration and movement which to them indicates a food source. They will feed on a source and then lay some eggs and so the process starts.

Adult fleas survive on blood, feasting on a host via piercing and sucking mouth-parts, this is what people commonly class as a flea bite. Flea larvae consume various organic fragments such as particles of food and faeces. The most important part of their diet is part-digested blood excreted by adult fleas. Therefore, vacuuming and cleanliness is an important part of flea management, as removal of the larval food source can be advantageous. Vacuuming also removes 90% of flea eggs, 50% of larvae and up to 95% of adult fleas, so hoovering is always an important part of the treatment and an underrated method in the battle against the flea. You must however remember to remove the hoover bag and dispose of it in an outside bin as soon as you have finished or empty a bag-less hoover in an outside bin or there is a good chance you will re-infest a room or even other rooms with fleas.

It is difficult to see fleas, due to their small size but you normally become quickly aware of their presence after receiving a flea bite. Fleas breed rapidly and need immediate professional treatment, as an infestation can become unbearable to live with. You can spend vast amounts of time and money attempting to rid your home or office of fleas to little success. This is because the longevity of the flea life cycle, and flea pupal can lay dormant for up to 2 years. You can do some self-help and the most obvious one is to regularly carry out a flea treatment on your pets. Just because they do not have fleas, does not mean you should stop treating them as this is when they become most vulnerable.

The Flea Treatment

Pest-Tech Ltd have a strategy for flea control and the first part job is to survey the property or workplace to establish what the extent of the building is infested with fleas, Identify the species of flea we are dealing with. If a flea monitor is deployed, then it will capture adult fleas and the sticky pads can then be submitted to an entomologist for reliable identification. Where host animals are present, we ask the occupier which areas are frequented by their pet, these are likely seats of flea activity.

Prior to the treatment we issue Pre-Treatment Preparation instructions to ensure the property is prepared as best to get the best results from the treatment. Firstly, would be vacuuming the premises, paying attention to floors and upholstered furniture. The purpose of this is to remove animal hair, organic debris and eggs, larvae, pupae and adult fleas. An added benefit of vacuuming is that the vibrations can trigger adults to emerge from their dormant pupal stage. Of course, this is when the adult fleas begin to contact insecticide deposits. Steam cleaning may be necessary as an additional measure in more dirty or challenging conditions. Vacuuming efforts should be focussed under furniture, chairs, sofa cushions, cracks and crevices in floors and along walls, all wall-floor junctions, as these are areas typically frequented by host animals like cats and dogs. Take care to dispose of the contents of the vacuum cleaner securely and in an outside rubbish bin to minimise the risk of transferring fleas throughout the property. We request the bedding to be removed and placed in the wash (60 degrees) to deal with any fleas etc on the bed. We ask the owner to ensure access to as much floorspace as possible, so the whole area can be treated this includes removing clothes lifting shoes and moving any other items to free up floor space. We recommend that concrete and tile floors are swept and washed. Any clothes that have been on the floor are to be placed in the wash the same as the bedding. Pet bedding should be washed or disposed of to remove fleas and all other stages of. We ask that if the owner has pets then they are advised to treat their animal with a relevant flea control product. This provides the greatest chance of total control as both the residence and host have been appropriately treated.

The flea treatment entails a spray treatment with a high-quality residual insecticide within the guidelines of the label directions. An insecticidal fog mist will also be used to get into all the cracks and crevices to agitate the adult fleas to get them moving about into the path of the treated areas Insecticide residues should be left undisturbed for as long as possible to ensure maximum residual activity. The key point regarding insecticide use is to follow product label directions.

If you have a flea infestation and you would like to talk about having a treatment carried out, then please give Pest-Tech Ltd a call and we will be able to help you.

The larger capacity bag-less vacuum cleaners are not disposed of as frequently and securely as the more traditional bag cleaners with the loose contents, tipped into the kitchen waste bin, rather than a small old-style bag being tied up and disposed of in an outdoor bin. This is not to say that vacuuming is a bad idea in flea management as long as you discard the contents in a bin outside. Remember to use a HEPA filter vacuum cleaner to prevent the re-circulation of insect fragments which may cause allergic asthma.
