Wasps in February

At PEST UK we have been receiving an unusually large number of enquirers regarding wasps in February. This is unusual as wasps in February should still be in hibernation. It may be that the uneasily warm Winter weather has effected their hibernation cycles. It is only the Queen Wasps that are alive at this time of year. All other forms of wasps (the Drones and workers) die off in the Autumn and early Winter. Any wasp nests now are ‘old’ nests and are not active nor will they be inhabited. We often get calls from people wishing to have old wasp nests removed and of course we will do this but generally it isn’t needed and serves no purpose. The Queen wasps that are present at the moment do not inhabit a nest in fact they will attempt to start a nest in the Spring once they come out of hibernation (usually April, depending on the weather).

Treatment for Wasps in February

This can be done but treatment for wasps in February is more complex than treating a wasp nest in the Summer. This is because a wasp nest is in a fixed location and can’t move and the wasps are fully active so an application of insecticide can wipe out a wasp nest in a matter of hours. Dealing and treating sing Queen wasps in February is a bit different. First the Queen wasps will be spread out over a wide area and secondly the metabolism of the wasps will be slow, leading to a slow uptake of insecticide and dining may take a while. So a wasp treatment in February will reduce but not fully eliminate the wasp problem and may take some time to work. It may also be slightly more expensive as insecticide may be applied to a wider area, probably using an insecticide fogger, an insecticide smoke generator, a residual insecticide spray or a combination.

Will the extremely warm Winter of 2015/2016 affect the 2016 wasp nest season? Do wasps & warm winters

It is often assumed (wrongly in my opinion) that very cold weather will kill hibernating Queen Wasps. The reason I don’t believe this is that the same species of wasps we have in the South of England are also in Scotland, Scandinavia and Northern Europe. That said cold weather in late or early spring may have an effect. The worst time for Wasps in regard to very cold weather is in the Spring. If the weather is mild enough, it could lead to early emergence from hibernation by the Queens, and they will lay eggs. If there is then a heavy frost, it will kill the eggs and any grubs that may have hatched (these are not designed to hibernate as the Queen Wasps are). If the cold weather starts early in the Winter then this may prevent the Queen wasps from feeding and building up reserves to survive the Winter in hibernation. The worst enemy regarding the weather is severe fluctuations in temperature.
Wasps & Warm Winters
Queen wasps can be a nuisance in domestic situations as they emerge from hibernation, either at the correct time (March/April) or any time before this when they can be affected by artificial light and/or heat generated by a house.
PEST UK can treat Queen wasps by applying a residual insecticide to the areas where they are coming from. Typically this may be in the loft or other dark cavities that suit queen wasps to hibernate.

Wasps coming out of chimney

If you have bees or wasps coming out of a chimney it may be that you have had a wasp nest in the chimney the previous year, it may just be Queen wasps hibernating in the chimney or worst case scenario it may be that you have an established honey bee nest in the chimney.
Wasps coming out of chimney
What can I do about Wasps coming out of the chimney in Winter?

There are no ‘active wasp nests in the Winter. This is because each wasp nest dies off in the Winter leaving fertile Queen Wasps as the only survivors who leave the nest, disperse over a wide area and hibernate. Chimneys, lofts and other cavities are often chosen as hibernation sites. it must be stressed that the Queen wasps are acting individually, there are no active wasp nests in the Winter. You may never ‘cure’ the problem completely but the application of a residual insecticide up the chimney applies with a pressure duster will relieve and sometimes solve the problem. PEST UK can do this for a reasonable price.
Bee Control by PestUK
What can I do about Honey Bees coming out of the chimney in Winter?

This is far more difficult. One of the main differences between Honey Bees and Wasps is that a Honey Bee nest will live for many years and be semi dormant in the Winter (in both cases of hibernating Queen wasps and semi dormant Honey bees) artificial heat and light may ‘pull’ them out of hibernation and lead them into dwelling areas. As a temporary measure a residual insecticide can be applied to the chimney in the same manor as for Queen wasps coming out of chimney but to completely eradicate a Honey bee nest is a difficult task. It has to be done when the temperature is high enough for the nest to be completely active and usually has to be carried out from the roof using 2 people and a roof ladder etc. PEST UK can do this at a cost of £135.00 + VAT.
Tackling a Honey Bee Swarm in a Chimney
If gas appliances are venting into a chimney and you suspect there is a wasp or bee nest in the chimney then you must stop using the gas appliance that vents into the chimney immediately. If you continue to do so the the consequences could be fatal.

Wasps in January

At PEST UK we are still getting calls from customers with pest control problems concerning wasps and wasp nests. Usually this involves people getting Queen wasps coming into rooms from the loft or other cavities where old nests were and/or Queen wasps have chosen these sites for hibernation. The unusually warm weather coupled with artificial light and heat can make Queen wasps think it is Spring and time to come out of hibernation.
Wasp Nests January
What can be done about Wasps in January?

One solution is to apply a residual insecticide and /or an insecticide applied through a fogging machine. This kills wasps but rarely will this type of treatment eliminate the wasp problem immediately as the metabolism of hibernating wasps is very slow which means once they come into contact with insecticides it may take some time to die. The other reason is that hibernating wasps are spread over a wide area and the insecticides applied may not reach all areas of a loft or cavity. Having a wasp treatment will also reduce your chances of getting a wasp nest or wasp nests the following year. Queen wasps come out of hibernation March-April and start a nest into which lay lay eggs. The eggs hatch into grubs which are fed by the Queen wasp and then they pupate and hatch into worker wasps. The population increases from just the Queen wasp in April to several thousand by mid July.


Prices for treating wasps in January start at £65.00 + VAT, depending on the size of the house and the area that needs treating.

Wasps – Advice from the BPCA

Wasps coming into rooms from lofts are a common problem in the winter. This usually means that there has been a wasp nest, or even multiple nests, for quite a long time, and the wasps in the nest are now dying out. It is not uncommon for wasps to have a nest in a loft, and complete their whole cycle undetected – starting in the spring and finishing in late autumn/early winter.

Why do I have Wasps Coming from the Loft in December?

Wasp PEST UKThe reason is, that although a wasp nests only lasts a year and will die out if left alone they produce new queens for the following year. These Queen wasps have mated with Drone Wasps (the males) from other nests in the Summer and leave the nest in late autumn/early winter to hibernate. Each nest can produce hundreds, and in large nests up to a thousand, Queen wasps for the following year. These Queen wasps leave the old nest and disperse over a wide area. They hibernate, but can cause problems because artificial light and warmth in a house can confuse them and draw them into living areas.

Treatment for Wasps Coming from the Loft in December

Wasp Control from PestUKPEST UK can apply an insecticide ‘fog’ to the loft area as well as a residual insecticide spray to areas inside rooms (usually walls & ceilings) where wasps are being seen. This type of treatment will reduce the problem but does take time to work as the wasps’ metabolism is very slow so the uptake of insecticide can take some time (2-3 weeks). All the insecticides used by PEST UK are virtually harmless to all mammals.


Price for Treatment of Wasps Coming from the Loft in December

Price for a fogging/residual spray treatment is generally £65.00 + VAT for up to 3 bed house.

Wasp – Information by the BPCA

Wasp PEST UK The cold does affect wasps and severe frosts can kill adult wasps (Queen wasps are resistant to frosts once in hibernation) but generally the cold weather just slows down wasps and can even extend their life. The reason for this is that the lower temperature will slow down the metabolism of the wasps so they don’t suffer ‘burn out’, unlike wasps in the height of summer when they may be active for over 15 daylight hours and then still work fanning the wasp nest at night to keep it cool. Worker wasps  working in hot conditions are thought to have a lifespan of 6-8 weeks whereas wasps operating in lower temperatures and shorter days will live much longer. When the days are colder and shorter wasps may remain inactive for days at a time, only becoming active once the days become warm enough. This process cannot continue forever, and eventually the whole nest (apart from the ‘new’ Queen wasps) will die out.

So, does cold kill wasps? The short answer to this question is ‘No’!

Cold weather wasp problems arise when the wasp nest is in a house and it becomes affected by the artificial conditions of heat and light supplied by houses – without this artificial stimulation the wasp nest would pose no more problem. These artificial conditions can draw wasps out of nests and into contact with people. Wasps that are ‘pulled’ out of a nest in these conditions are more likely to sting people, and in fact we find that more people get stung by wasps from October to December than in the height of summer.

Wasp NestPEST UK can treat wasp nests or the areas in a house afected by wasp problems in cold weather, either by treating the nest directly and/or applying a residual insecticide and/or ‘fogging’ insecticide treatment to give relief to the wasp problem. It must be remembered that any inserted treatment when insects are cold takes much longer (wasp problems treated in December may take 2-3 weeks to work.

Wasps BPCA

There are several reasons why it is beneficial and less dangerous to have a wasps December treated. It is true that a wasp nest will eventually die out naturally but last year we were still treating active nests in the last week in December! If you do decide to leave a nest to die out then you are more likely to get wasp nest(s) next year. A nest will produce hundreds (in some cases thousands of fertile Queen wasps. If a nest is treated then the vast majority of these Queens will be killed and so reducing the risk of that nest causing new wasp nests the following year. The Queen wasps leave the nest as it dies out. They then hibernate for the remainder of the year and come out of hibernation in April to seek out a site for a new wasp nest. Each Queen wasp will start her own nest.
Many people get stung by dozy wasps at this time of year. They get lost and because it is colder and the days are shorter they are more likely to be attracted to artificial light and food sources which brings them into contact with people. Many people get stung by wasps that have crawled into clothes or bedding. If you don’t have a wasp nest treated then it is like that dozy and dining wasps will be seen for some time.

BPCA Information Wasps

At PEST UK we often treat active wasp nests in December. Can cold kill wasps? Not usually, it is usually old age. In fact cold weather can actually extend a wasp’s life, not kill wasps. In colder weather the metabolism of the wasp slows down so they are not doing as much which extends their life. Like putting something in the fridge. A worker wasp in the Summer lives 6-7 weeks but later due to lack of daylight hours coupled with cold weather this can be doubled. An example of cold effecting another insect is the Cluster Fly. A hibernating fly can live 4-6 months where as an active cluster fly in the Summer may only live a matter of weeks.
German Wasp
Is a nest worth treating in cold weather?

More people get stung in the Autumn and early Winter than in the Summer. The reason for this is that the worker wasps are dozen and find it harder to get away and are more likely to crawl into places where they come into contact with people (in clothes or beds for example. In the Autumn the worker wasps are also more likely to be feeding on fruit which brings them into contact with people again. In early Summer the workers concentrate on collecting caterpillars, flies and other insects to feed the new grubs in the wasp nest.

It is true that if you leave a nest it will eventually die out naturally. The wasp nest actually starts to shut down in August, this is when grub production ceases. The last batch of grubs are the Queens and Drone wasps (these are the only fertile forms of wasps, the Queens being the females and the Drones the males, the majority of the population of a wasp nest are the workers who are all sterile females). These Queen and Drone wasps mate with Queens and Drones from different nests. Once these Queens and Drones have been reared then the workers do not have to collect food for the grubs, this affects their diet and behaviour. The food they collect for grubs is a protein meat diet consisting of caterpillars, grubs, flies and other insects which are mashed into a paste then fed to the grubs. In exchange the grubs produce a sweet substance which the workers like, this encourages the worker wasps to feed the grubs. This process ends once the Queen and Drone grubs are mature. Worker wasps now start feeding directly on sweet substances. This change of diet corresponds with the fruit season. Wasps feed on ripening fruit, get drunk and bold and more aggressive.People are more likely to be stung by wasps in the Autumn than at any other time. The other two main issue with wasps in October and November are light and temperature. Wasps are attracted to light and as the days get shorter artificial light becomes a big attractant which brings them into close contact with people. Lower temperatures make the wasps dozy and liable to crawl into areas where they can sting people.
German Wasp
So, is it worth treating a wasps nest in October – yes, because not only do you reduce the risk of getting stung you also reduce the risk of having another wasp nest(s) the following year.

BPCA Wasps

Wasps can be a real problem during summer in the UK. Between May and November we get many reports of wasp nests that need to be treated.

Wasp stings can be potentially fatal to people who have allergies, and even for those who don’t they can cause a painful sting. Unlike bees, wasps can sting multiple times, and they will attack if their nest is threatened. They are also able to communicate a sense of danger quite quickly, and when threatened, it is a matter of seconds before an entire swarm appears from within the nest to tackle the danger.

This is why it is best to get the experts in. As this short video show, we make it look easy, but that’s because we are trained and we have the correct protective equipment, and the right treatment.

Once a nest has been treated the worst of the problem is solved, but it is a good idea to leave the nest in place for a few days, so that wasps who were not in the nest will be able to return to it and succumb to the treatment. If the nest is removed too quickly, these wasps can hang around the area for days after the nest has disappeared.
