Explain What Actually Happens When a Wasp Nest Is Removed From Your Roof

There is a wasp nest in the eaves, an unhelpful amount of internet advice, and a callout fee that varies wildly by postcode. This explains what treatment actually involves, how long until it's genuinely safe, and when DIY is fine versus a bad idea, so you book the right thing once.

**Explain the process in stages:**
1. What actually happens during professional removal, from arrival to treatment
2. How long it takes for the nest to stop being active, and what "safe" actually means during that window
3. What DIY options exist, and honestly, when they are a bad idea
4. What to do about the nest itself afterwards, and whether it needs removing physically
5. What to check before booking, including treatment guarantees
