Bedbugs: why the cheapest quote should worry you most
The gold standard is heat treatment: raising room contents above roughly 45 to 50 degrees Celsius for a sustained period, which kills adults, nymphs and eggs in one pass, including inside furniture where no chemical reaches. It requires specialised heaters, careful monitoring, and preparation such as removing heat-sensitive items, so it costs more than spraying and sits at the upper end of residential pricing. Chemical programmes can still work, but only as a series of two or three visits spaced to catch newly hatched insects, combined with mattress encasements and thorough vacuuming.
When comparing bedbug quotes, be suspicious of any provider promising a one-visit chemical cure at a rock-bottom price. Ask whether the price includes follow-up visits, whether heat is available, and what the warranty says about reinfestation. In shared buildings, mention the problem to building management, because treating one unit while the neighbouring flat stays infested rarely holds.
