Treatment Process

Please allow a minimum of 14 days to action a secondary treatment unless otherwise stated by your pest controller. You may still see wasps during this time.

Do not leave for longer 21 days to contact your pest controller.

Don't worry if you are still seeing wasps, as long as you're seeing a decline then the treatment should be working as expected. It can take up to 14 days for a colony to die off completely. Some are much faster and die within 2 hours whereas more complex issues might need additional treatments which will incur additional costs. Please note, (see size chart below) If the nest is reasonably small and accessible it may be dead within a couple of hours however, if it is a medium to large nest and / or in an awkward location it may take notably longer to die off.

Weather can affect treatments - during rain your appointment may need to be changed, equipment used to administer insecticides can clog and treatments can be less effective. Light rain and drizzle should be fine.

If you have any queries during this time please text message your pest controller and he will call you back ASAP as he will likely be on another job. If wasps are getting into your property please read through the sections called Pests in your property and Risk reduction

UK law has changed considerably, stronger insecticides previously available are no longer. Depending on size and location of the infestation and to eradicate the nest fully a number of treatments may be needed. If the actual nest is visible we can use other solutions which are guaranteed in one visit.

What to Expect

Initial treatment

During treatment wasps can be highly aggressive with many swarming, the majority of wasps defending the colony will stay close to the entry point but some will try to find the source of the attack and defend. It is strongly advised to stay indoors whilst the treatment is carried out and to keep a safe distance from the nest. Keep windows, doors and vents closed.

These wasps are likely to stay close to the entry point for a while. This can be hundreds of very aggressive wasps depending on the size of the colony.

This is the normal flow of treatment phases

Next Couple of Hours

During the next couple of hours worker wasps will return from foraging, increasing the number of wasps collecting at the point of treatment, this is due to distress pheromones released by the wasps. The defending and returning foraging wasps are highly likely to be far more aggressive

There should be a good decline of wasps seen on the outside of their entry point as they either die off or return to normal duties now the initial threat of the pest controller treating the nest has passed. As an example the decline should be around 80% or less of initial activity

You may still see wasps for a few days but reducing - if there is zero decline after 4 to 5 days text message your pest controller and they will call you back ASAP. Please text rather than call as we can get extremely busy and maybe on a roof. A further treatment may be required.

After a few days to 2 weeks

As the days go by there will be a considerable decline in wasp activity and there should be no sign after 2 weeks. Do not worry if you see the occasional wasp, this is usually due to foraging wasps from other nests investigating as they are attracted to the smell of the dying nest.

It is also important to note that from time to time eggs hatch and new wasps will emerge however, the insecticide stays active for a longtime - these newly hatched wasps should soon touch the insecticide and die off.

After 2 weeks

If after 2 weeks you are still seeing a number of wasps coming and going then you will need a further treatment which will incur an additional cost.
If only one or two wasps then it may just need a few more days

Monitor the area

Monitor the area for a few days only if at a safe distance - do not monitor if you are unsure of your safety - there should be a notable decline.
To avoid future invasions it is advised to seal entry holes to the nesting area but only when wasps are not prevalent. Wasptec can advise on prevention.

DO NOT SEAL WASPS IN.

If wasps come into the house, seal access points to keep wasps out, such as sides of attic hatches, gaps 2mm or more (occasionally smaller), air vents, holes around piping, gaps in flooring, anywhere where a chink of light which might shine through and be a likely entry point. Check ceiling lights and loose fixtures amongst others. Wasps can chew through certain materials.

Keep people, children and pets away as wasps can attack, particularly when feeling threatened. A sting can cause allergic reactions. In some cases anaphylaxis, which can be fatal. In the event of an emergency contact 999 ASAP.

Additonal Work

After treatment of a wasp nest, a quiet period often occurs as the treatment affects the wasps. However, survivors may return for several reasons:

Surviving Wasps: Some may have been outside the nest for longer than normal during treatment. Shut in homes, sheds etc
New Wasps: Remaining larvae can mature, causing renewed activity. No treatment available will kill the eggs and they can still hatch. However these new wasps will soon be contaminated by the insecticide.
Pheromones: Other wasps may detect pheromones (smells) indicating there is a nest present.
Nest Size: Larger nests will take longer to fully eradicate. If conditions are right and there's space to build the nests can grow to huge structures. The size of a car is not uncommon.
Treatments

The insecticide will still be active. In most cases the emerging wasps will touch the insecticide and die off

You must allow a minimum of 14 days before actioning an additional call out for the treated colony unless otherwise stated by the pest controller. Repeated treatments may be necessary for complete elimination and incur additonal costs.

Be Safe

Secondary Nests - Robber bees?

It is not uncommon to have a number of nests on your property. These can emerge over the course of the season. If additional nests are found on the property at the time of visit we can treat at a good discounted rate subject to location, size, accessibility etc .

However, wasps start building in conjunction with the queen emerging from hibernation, so wasp nests can be constructed over a 2 month period. New nests are charged at the normal rate.

Text message your Pest Controller

Remove the Nest

A treated wasp nest will have traces of poisons surrounding and within the nest, these toxins can remain active for a long time and it is advised to have the nest removed. Contact Wasptec. Nests may also be attached to electrical wiring which could be compromised leading to potential fire hazards. Having the nest removed can also help reduce the risk of secondary wasp nests as they have a smell that can attract other wasps.

Wasps in your Property

While we appreciate wasps in the property can be very disconcerting there are things that you need to do to reduce the risks of them entering.
We strongly advise you to read through the section called Pests in your property and Risk reduction

Wasps Under Roof Tiles

If you have wasps under the roof tiles the likelihood is that the felt under the tiles has been damaged leading to possible water ingress. Wasps will chew through the felt in order to enlarge the colony. It is strongly advised that after treatment to have a roof inspection, this will involve removing the roof tiles. This can be costly as scaffolds may be required but can save thousands if water penetrates walls, ceilings etc.
