First is a Bumble Bee then a Honey Bee a Hornet and Finally, a Wasp. It is clear to see the differences between them. If you have wasps, then read on.

How Long Have Wasps Been There?

Wasps normally begin building the nest in the spring between February and May. The exact times are dependent on the kind of weather and temperatiures we have experienced and this of course varies from one year to the next.

For the most part it is fairly accurate to assume that most (definitely not all) nests are started in April and double in size every four weeks. So by July, most nests are the size of a good sized football and by the end of the September have fully matured, and are the size of a beach-ball.

The first layer of cells might raise a dozen wasps and the third or forth layer of cells could contain a thousand or more that hatch in quick succession. This is why people often say that the nest has just appeared, because hundreds of wasps hatch within days of one another.

How Big Will The Wasps Nest Be?

The physical size can vary in different ways and for very different reasons.

The first reason is species. We have nine species of social or paper wasp in the UK and five are found in Bristol. The Tree Wasp and Median Wasp are large wasps that produce nests the size of a football in structures, trees, shrubs and hedges etc.

The German Wasp and Common Wasp produce colossal nests in cavities like lofts, holes in the ground, lawns and garden sheds etc, that can be the size of a car! They are sometimes called lawn wasps.

Finally the European Hornet prefers cavities like those found in bird boxes and attics. These nests are similar in size and appearance to an upturned bucket.

Not all wasps nests are of uniform size and shape. Some nests are built to fit around the space constraints imposed on them by the structure they are in, so we see every conceivable shape from heart shaped, to flat and the downright weird. Nature at its best.

How Many Wasps Are in A Wasp Nest?

Again this will vary with species. Tree wasps, hornets and median wasps will normal have nests with no more than a few thousand insects at most. The German Wasp and Common Wasp produce huge nests that can contain tens of thousands of wasps and if disturbed can prove fatal.

What Will Happen if You do Nothing?

Sometimes times, absolutely nothing. But a large nest has the potential to quickly get to big for the space in which it was built and this will encourage the wasps to try and increase the size of the cavity by excavating it with their powerful mandibles.

This sometimes brings them through ceilings and walls with the worst possible consequences for anyone in the room. When this happens at night, they are often drawn to the light of bedside lamps and night lights waking the occupants from their sleep in absolute terror after being stung multiple times in their sleep! This is not a rare occurrence, we see it EVERY year.

Is Wasps Nest Control Dangerous?

No - at least not at first. A can of wasp killing foam, dust or spray will quickly overwhelm a small nest and you should remain sting free.

Once a wasp nest reaches the size of a small football the tables quickly begin to turn back in the wasps favor. It's not the wasps in the nest that are the problem, more the wasps that are returning, and many DIY wasp control attempts have ended in disaster when returning wasps have attacked from behind!

It should also be noted that a loft space is not a good place to attack a wasps nest because it can be dreadfully impracticable to escape from quickly, especially if you split a large nest and are swarmed by hundreds of wasps at once. This how people get killed, falling of ladders, falling through ceilings and down stair wells. It's just mot worth the risk.

How Are Wasps Nests Controlled?

Most nests found in cavities are treated with an insecticidal dust delivered via pressurized equipment to deliver the dust deep into the nest or its surroundings and entry point. The dusts used by professionals are many times stronger than those sold to amateurs!

Aerosols are also used to subdue large numbers of "flying" wasps, especially where they start to swarm. They are a great backup for high risk nests or treatments in confined or sensitive spaces.

Oil based, pesticide sprays are highly effective in subduing nests but run the risk of causing damage to items surrounding the nest so are not that popular professional.

Wasp Killing Foams are commonly used by amateurs and can be great for nests that ARE NOT inside cavities. Covering an accessible nest with foam can work well but it does not subdue the wasps quickly so you might get badly stung!

How Long Does a Wasp treatment Take?

Some nests are treated in minutes, others can take over an hour. The clearer the access, the faster the treatment. Don't get caught up with time! the dusts used professionally rely on the wasps as a vehicle.

The treated wasps take the chemical into the heart of the nest giving a systemic kill. It can take an hour for wasps to return to the nest and a further ten minutes for them to come into contact with the chemical and die. Temperature, wind speed and rain will all take a toll treatment times.

As a rule a pest control operator will average about twenty minutes on site, but the result is whats important, and a safe and effective one at that. All our treatments are usually guaranteed.

What Safety Precautions Should we Take?

Everyone who could be affected should be informed and all windows and doors should be closed for at least a few hours following treatment. Telling neighbors, especially those with pets and young children is a must, because treated wasps will spiral to the ground.

Wasp control dust can also drop out of treated cavities, especially when treating vertically and this can drift onto neighboring properties, water features and persons etc. So being prepared keeps every one safe and free of accusations and upset.

What Will We See?

Immediately after treatment wasps returning to the nest will cluster at the entrance. Clustering wasps can cause alarm, but it shouldn't as it's quite normal.

When clustering doesn't happen, chances are the treatment will have failed. Once each wasp is exposed to the chemical, it will die within minutes.

Most of the wasps die off site as they fly away, sometimes completely white, covered in the dust.

What Happens After a Wasps Nest is Treated?

Within an hour of the nest being treated you should expect almost complete cessation of activity. If the wasps seem more active than ever, it might require another treatment.

In colder weather, wasps that hatch from cells in the treated nest might appear in random places around the building and again this is normal. If this problem persists for more that 21 days, chances are the treatment has not worked, but more likely you have another wasp nest!

Can Dead Wasps Still Sting You?

NO! The sting can still pierce the skin, but cannot deliver venom.

Why Don't You Remove Wasp Nests?

Removal of wasps nests removes the very chemical that could prevent future nests developing. The dusts used have a shelf life of three years, so will continue killing for many months at the very least.
