Emergency Bed Bug Heat Treatment High Ongar CM5
High Ongar (CM5) is a Epping Forest village with period cottages, converted farm buildings and detached family homes. Heat treatment clears bed bug infestations in a single visit — adults, nymphs and eggs — without leaving chemical residue or damaging original timber.
Bed Bug Exterminator High Ongar — How We Work in CM5
On a typical High Ongar job, two technicians arrive with Acrotherm EC85 heaters, ducting and FLIR thermal cameras. The property is brought up from ambient to a sustained core temperature of +141 °F, held long enough to penetrate mattresses, sofas, skirtings, floor voids and the wall cavities common in CM5's older stock. Eggs, nymphs and adults die in the same visit. There is no spraying, no residue, and nothing to re-spray a fortnight later.
