How to spot a bed bug infestation early
Bites in lines of three, tiny blood spots on sheets and a sweet musty smell are early warning signs. Catch it before the population doubles.

Full report, thermal logs and a 6-month written guarantee.
Specialist industrial heat equipment tuned for Essex's mix of period cottages, semis, new-build flats, HMOs and hotels — raising and maintaining temperatures throughout every affected area, from mattress cores to skirting voids and cable trunking.
We inspect beds, mattresses, sofas, skirting boards, sockets and wardrobes, then discuss infestation history and any rooms needing special attention.
This must be completed the day before our initial assessment. Remove aerosols, candles, medication, batteries, electronics, plants and delicate plastics. Clothing, bedding and furniture stay in place to be heated properly.
Industrial heaters, air movers, ducting and thermal monitoring are positioned carefully to circulate hot air into every void and harbourage point.
Temperature rises gradually so heat penetrates deep into furniture, mattresses, gaps and structural voids where bed bugs live and breed.
Thermal imaging cameras monitor every area in real time, detecting cold spots and confirming lethal heat levels are reached and maintained throughout the property.
The property is held at treatment temperature for a set period. Adults, nymphs and eggs must be exposed to lethal heat long enough to be fully controlled.
Technicians move and rotate furniture, mattresses and cushions to eliminate cold spots and ensure complete heat coverage on all sides.
Key harbourage points are checked again after treatment. Findings are recorded and post-treatment guidance is provided before we leave.
A small number of dying bugs may appear briefly. Bites can continue for 2–3 weeks due to delayed skin reactions. Do not move items between rooms.
Live video evidence is required for any follow-up claim. Our team reviews the footage, advises on next steps and arranges further treatment under guarantee terms.
We're RSPH-trained and fully insured — with unmarked vans, discreet arrival and same-week availability across Riffhams and the wider Essex area. Every job is verified with thermal imaging and backed by a 6-month written guarantee, so you know the infestation is finished the day we leave.
