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.
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.
