PPC117 | Ask the technical team
Wasp numbers, expanding foam, qualifications framework and wildlife crime reporting all feature in this issue of Ask the BPCA technical team.

SPEED READ
- The wasp season has been terrible, but it’s not likely that hornets are the cause
- A qualification framework has the potential to elevate the pest control sector to higher levels of professional recognition
- Expanding foam must be used with caution
- Wildlife crimes should not be reported to BPCA but to the WIIS.
Have European and Asian hornets had an effect on wasp numbers this year?
The wasp season this year has been terrible and the most likely cause is the weather.
Bad weather will delay the emergence of queens in spring and, when they do emerge, there’s likely a reduction in food source (small invertebrates) for the queen to be as productive.
European and Asian hornets are known for their predatory behaviours and competitive interactions.
However, the quantity of confirmed Asian hornet sightings in the UK at the current time is probably too low to make any real impact on nest numbers just yet.
Of course, disruptions in the natural balance of our ecosystem, such as the arrival of an invasive pest species, does highlight concerns about the potential ecological consequences in the future.
Is expanding foam safe to use for pest control proofing?
Expanding foam can be used for pest control proofing, but it must be used carefully and by the manufacturer's instructions.
Some expanding foams may contain chemicals that could be harmful if not handled properly, so it's essential to take necessary safety precautions when using them.
It's also important to consider the specific pest you target and whether expanding foam is the most effective and safe control method.
Expanding foam wouldn’t prevent rodents from accessing the hole without using a material such as wire wool in conjunction with expanding foam.
Always be careful when using wire wool around electrics as this carries a fire risk. Expanding foam labels must be read carefully and you should avoid use in areas of potential ignition, such as around boilers.
We already have qualifications - why have a new framework?
You're right, we do - we have the BPCA/RSPH Level 2 Award in Pest Management as our default entry-level qualification. But it's up for review (like all Ofqual qualifications), and unfortunately one or two qualifications don't make a framework.
We have the opportunity to set the bar a little higher and make some new higher-level qualifications for everyone looking to develop their careers, skills and knowledge.
We can make our qualifications less about passing written exams and more about measuring competency. We're practical people, so sitting a three-hour exam can't be the best way to assess new techs.
Crucially, it will also make the industry a more appealing option for people looking at starting new careers. A proper framework will show what the sector has to offer in terms of upward mobility/career progression, which is a huge factor in people’s decisions when it comes to choosing jobs.
We also know how tough changes to the industry through legislation have been. A qualification framework can contribute to the industry's professionalisation by setting consistent standards for pest control practices.
We believe this will enhance the industry's reputation and credibility, ultimately leading to increased trust from the government.

Where can I report a wildlife crime to? You or CRRU?
You wouldn’t report wildlife crimes to either us or CRRU, neither organisation deals with those. You would report them to the Wildlife Incident Investigation Scheme (WIIS).
WIIS investigates incidents in the UK involving wildlife, such as illegal poisoning, shooting, or trapping of protected species.
WIIS works with other organisations, including the police, to gather evidence, identify perpetrators, and prevent further harm to wildlife.
The scheme plays a crucial role in enforcing wildlife protection laws. If you need to report a crime, you can call freephone 0800 321 600.
