Bedbugs: why the cheapest quote should worry you most
Bedbugs are the pest where cutting corners costs the most. They hide deep in mattress seams, bed frames, skirting boards and behind headboards, and they have developed resistance to many common sprays. A single quick spray visit typically kills the exposed insects, scatters the survivors into adjacent rooms and leaves the eggs untouched, which is why the infestation appears to vanish and then returns worse within weeks.
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.
