Fly problems in your home or business

Flies in February

Flies in February usually mean you have Cluster Flies. Especially if flies seem to be coming from the loft area but they can come fro any cavity. They will use the cavity for hibernation purposes. They will not be breeding or feeding but hibernating. Harlequin LadybirdsHarlequin Ladybirds may also be hibernating along with the Cluster Flies.

Once a hibernation site has been chosen you will always get some flies hibernating there. How many depends of the success of any pest control treatments as well as how successful the flies were breeding throughout the Spring, Summer and Autumn. They have genetic memory where even though they have never seen or been to the hibernation site that there parents or great grandparents hibernated in, they go to hibernate at the same site. Before humans arrived on the planet and started building houses, these Cluster Flies and Harlequin Ladybirds would use caves or hollow trees as hibernation sites. Now humans have erected so many buildings these insects have as many sites as needed. This may artificial boost the population. Although PEST UK cover many towns in the South of England (including Alton, Ascot, Basingstoke, Bracknell, Camberley, Farnborough, Farnham’ Fleet, Guildford, Harrow, Henley, High Wycombe, Hounslow, Maidnehead, Newbury, Northwood, Ottershaw, Reading, Slough, Tadley, Thame, Thatcham, Uxbridge, Windsor, Winnersh, Woking & Wokingham) most of our calls regarding flies in February come from Hounslow, Bracknell and the Reading areas.

Flies in Lofts

February, March and early April is the time of year when people find flies in lofts or flies emerging from lofts. These are usually ‘Cluster Flies’ of which there are several types but the most common type looks slightly larger than a house fly but smaller than a Blue Bottle. It is important to understand that this type of fly will not be breeding or feeding, these flies in lofts are actually hibernating and the reason they are present at this time of year is because they are coming out of hibernation. This emergence process can take several weeks depending on the ‘natural’ weather as well as artificial sources of light and heat generated by a house. In late Spring, Summer and early Autumn the most common species of Cluster Fly is parasitic on earthworms, laying eggs in the soil which hatch into grubs that borrow into the soil and bore into an earthworm that they feed off.

Treating Flies in Lofts

PEST UK specialise in treating flies in lofts. We use either one or both of the following methods of insecticide control. 1. An insecticide is applied with a ‘fogging’ or ‘misting’ machine. This is ideal for lofts and gives a quick knockdown but the drawback is that it is not as residual as: 2. A residual surface spray. This is long lasting (up to 2 months inside on clean non porous smooth surfaces). Often both are used as loft surfaces are not really suitable for residual inside sprays. None of the treatments will eliminate the fly infestation but will reduce the fly population. As the survivors defendants come back to hibernate in the same place in the Autumn it is worth having a treatment to reduce fly numbers in the future.

False Widow Spiders, Pest Control Contract & Thorid Flies:
Recently we have had numerous enquiries regarding Steatoda nobilisvor False Widow Spiders. Most of these calls are just people panicking due to the media coverage. A few customers actually book up a treatment. Spider treatments are not unusual. Even though spiders are actually good to have in a house and garden (they kill flies) many people are frightened of them and due to this we carry out spider treatments. This involves applying a residual insecticide to walls, ceilings and around windows. This type of treatment is quite common in North America and Australia.

When I sent of the spider specimen to our lab to confirm its identity, I also sent a fly specimen for id. This turned out to be be a type of Thorid fly. the customer actually was having a rat problem in the sewer and these flies probably originated there and the repairs to the sewer to prevent rat access into the house may have opened up access to the house to the flies or the flies may have been using the same route as the rats into the building. This is the more likely scenario. There are many types of Thorid Flies but one species is called the Filter or Sewage Fly due to its habit of breeding on sewage filter beds.
False Widow Spider
This week we have won a contract at a large independent hotel in Reading, Berkshire. This is for rodents and bed bugs. We started another rat job at a very popular restaurant in the centre of Reading. This restaurant was over run with rats. I don’t really know how it stays open. A visit from an EHO would close it but the owners are very relaxed about it. I don’t think they realise that the place would get shut down in an inspection occurred.

Harlequin Ladybirds & Cluster Flies:
At PEST UK we have experienced more calls concerning Harlequin ladybirds in the past 8-9 years. This is because mainly due to their hibernation habits. This species tends to be more numerous than the native ladybird and hibernated in greater numbers similar to Cluster Flies. We used to get calls from customers concerning the native ladybird as these hibernate in groups as well but they usually hibernate in smaller numbers in window frames where they would be a nuisance to people. There hibernation sites are rarely buildings while the Harlequin Ladybirds nearly always chose buildings to hibernate in. As with Cluster Flies the hibernation process takes time and Harlequin Ladybirds and Cluster Flies will often hibernate together. The Ladybirds may go into the hibernation sites then come out when the weather warms at midday or sunny periods. It is not thought that Harlequin Ladybirds do any damage except for displacing the native Ladybirds. In fact they may do some good with all the aphids they eat.

Harlequin Ladybirds were introduced into North America in 1988 and are now the most widespread lLadybird on the continent. There are currently 46 species of Ladybirds in the UK. Control for Harlequin Ladybirds from a domestic pest control point of view can only be done in buildings and on external walls and window frames. Treating on plants should be done with a garden insecticide labelled for the purpose although as this would kill native ladybirds as well it would be pointless as it would make no difference to the numbers coming into hibernation sites as they will come from a large catchment area. Treatment may involve a fogging insecticide treatment and the application of a residual insecticide to walls, ceilings, windows, window frames as well as external walls and window frames. Types of treatments may vary depending on individual circumstances.

WaspFly Traps:
One of the strange situations that is seen at this time of the year is holes in the ground with a mass of wasps buzzing round but no nest. This is the work of badgers. Badgers will dig up wasp nests and eat the grubs. They seem to eat virtually all of the nest s well. As this mainly happens in late Summer and Autumn I am assuming that this is when the nest contains the highest meat content. The reason for this is that this is the time when the largest grubs/pupae are in the nest, the Queen and Drone grubs. These grubs are the last ones that the nest will produce. The workers construct large cells into which the Queen lays eggs and to the diet the workers feed the grubs they turn into fertile females (Queens) and Drones. All worker wasps are actually infertile females. The nest at this time of year probably has the most protein content as these grubs are much larger than worker grubs and the nest is at the largest size it is going to be. The badgers must be immensely tough to dig up and eat a wasp nest. Doing this would kill most animals.

Badgers have increased in numbers over the past few years, this can be seen by the amount of dead badgers seen by the side of the roads and it is sad but probably necessary that they are being culled to prevent the spread of TB in cattle. To me all killing is a necessary evil but man has changed the environment and if we are to eat and live disease free then controlling other animals must be done. Why protest about killing badgers? I don’t see larger demonstrations about killing rats. These are clever sociable animals but there are no marches with children and old people with rat masks on happening.

Wasp/Fly Traps
Disposable Wasp Bag from PEST UK
I have been testing wasp and fly traps recently and found that so far the trap that catches the most is the bag type trap. This out performed the fly bag trap in wasps and flies by about 50 times as much. Test is still on going. We sell and instal the traps at PEST UK.

Flies & EFK’s:
Flies are not simple pests to deal with. For a start the control will depend on the type of flies. Many flies are not attracted to the Electronic Fly Killers or EFK’s. These machines are are favourite of the food & pest control industries. Food premises like them in many cases because they look good and are seen as a modern way to deal with flies. From the pest control industries point of view they provide a source of income from sales & servicing. Unfortunately the two main types of fly that have the potential to cause disease, the House Fly and the Lesser House Fly are not attracted to the uv lights in an EFK. Some will go in by accident but just in the same way they might go to a normal light. If situated in the wrong place theses machines may cause moths and flies to come into the food area from outside. They should not be situated near windows or open doors. There is now a move in the food industry to use the EFK’s with glue boards rather than an electric killing grid. The reason for this is that the electric killing grid will cause the flies to explode and there is a risk that parts of flies ma end up where they are not required!.With the glue boards the flies get stuck and no parts are lost. The disadvantage of these is that they are more labour intensive than the electric killing grid machines, they generally need servicing four times a year (glue pads replaced) instead of one a year.

In my opinion EFK’s should only be used after the area has been fitted with fly screens on the doors and windows.

I used to carry out a residual insecticide spray every three months to a chip shop in Tilehurst, Reading. They had this instead of EFK’s and it worked exceptionally well. I used Demand CS which is a slow release insecticide, ideal on walls and ceilings. The customer was exceptionally pleased with the result and had this treatment for many years until the site changed hands. They did say that towards the end of the 3 month period flies would start to appear so we removed a Spring spray so the Summer/Autumn season had a spray every two months.

To summarise, EFK’s have a place to in fly control, they look good but have a limited effect compared with other methods of control and prevention.

Cluster Flies:
At last the weather has got slightly warmer. This brings insects out of hibernation. One of the first to make a difference to a pest control company are Cluster Flies. These flies gather in cavities to hibernate for the Winter. They are not feeding or breeding but are only interested in hibernating. As man has erected buildings there are now unlimited ‘cavities’ to use as hibernation sites. Remarkably once a site has been chosen it is used every year. It is thought that the site location is passed down through several generations by Genetic memory.

The flies that come out of hibernation in the Spring only live a few weeks so it is thought their descendants go back to the same hibernation site, but this cannot be proved one way or another unless some one does genetic testing on the flies. There are several species of cluster flies the main one in the South of England being parasitic on earthworms. Flies normally prefer one side of the building (often the south side). Once they have left the hibernation site they mate and the female lays eggs in the soil which hatch into grubs that burrow into the soil and find an earthworm which they feed on. Once developed they leave the earthworm, move near the surface to pupate where they emerge as adult flies and the cycle continues.

It is thought that wet Summers lead to Autumns with high populations of Cluster Flies due to the availability of earthworms. The wetter the soil the nearer the earthworms are to the surface which makes finding them easier for the newly hatched grubs. Another common species throughout Berkshire, Hampshire, Surrey, Oxfordshire and South Buckinghamshire is one that breeds in cattle dung. This can lead to localised problems with cluster flies near farms with dung piles.cluster-fly

09012013388 09012013390 0901201339009012013392Past few weeks have been more of the same with the exception that there seem to be some Cluster fly jobs coming through. This is earlier than last year. I have just taken a call from a regular customer who had Cluster Flies last year in mid February but now has a problem (9th January). The recent flooding has increased the number of rat jobs that were on a slight decrease after the flood of jobs caused by the cold weather in early December. We have some decent size pigeon netting and spiking jobs coming up shortly. The general demand over the holiday period was very low. PEST UK was shut for longer than usual over this period due to holidays. We normally only close Christmas Day, Boxing Day & New Years Day but this year we also closed Sunday 23/12/12 and Sunday 30/12/12.

Paul went to service a contract we have at a block of flats in Slough and found the bin area overflowing with rubbish (see photo’s). Rat control is not just about putting poison down. The food source has to be addressed & as in this case the rats food source is plentiful so they will not be at all interested in eating poison bait. Even if some do they will not consume enough or feed on the poison with enough frequency to make any difference.

Had another strange job today was a lady whose daughter had a kitten that had lived at her boy friend’s house. The kitten died & the lady was getting bitten by some thing. This is quite common, all cats at some time in their lives support some fleas but if they are treated & the house hoovered on a regular basis, the fleas won’t bother humans (they often prefer women & children to men). So this seemed a straight forward case, until I asked more questions. The lady was getting bitten at night (indicating bed bugs), had bites not only on the lower legs (this indicates fleas) but on her arms & torso (Bed bugs) also the daughter & boyfriend were not getting bitten at the boyfriends house where the kitten had lived. No fleas or bed bugs have been seen. Treatment is being held off for now, I have advised to look for more evidence such as adult fleas or ‘spotting’. Spotting is small drops of partly digested blood secreted by the Bed Bugs after feeding.
