What to know
Bed bug treatment is structured to address all life stages, but eggs are the most resilient. Professional products kill exposed bugs and many eggs, but some eggs hatch 1 to 2 weeks after the application. The follow-up visit is timed to catch the newly hatched nymphs before they reach maturity and start a new cycle. Your role in the 2 to 4 weeks after treatment is to monitor, avoid spreading any survivors, and keep the scheduled follow-up. The most common cause of recurrence is moving items from a treated room to an untreated room during the post-treatment window. Bed bugs and eggs can survive in clothing, luggage, books, and small items for weeks. Keep everything from the treated rooms in those rooms until clearance is confirmed. If you must move items, bag them in sealed plastic and dry them on high heat before moving.
If you see new activity after treatment, do not apply DIY products. Contact us for the scheduled follow-up visit or, in some cases, an additional visit at no extra cost if the recurrence is within the contracted scope.
Stay in treated rooms
Keep all treated items within the treated rooms until clearance is confirmed. Do not move unwashed clothes, books, or soft furnishings to other rooms.
Monitor for new bites
New bites in the first 1 to 2 weeks may be from bugs that were already feeding before treatment. Bites after 3 weeks may indicate recurrence and need a follow-up visit.
Maintain mattress encasements
Keep the mattress encasement on for at least 12 to 18 months. Any bugs that survived inside will starve and die without a host to feed on.
Keep the follow-up appointment
The follow-up visit is when we confirm clearance or schedule additional treatment. Skipping it is the most common cause of full recurrence.
Practical action plan
- Keep the affected rooms undisturbed for the first 24 hours after treatment. Avoid moving furniture, vacuuming, or cleaning surfaces.
- After 24 hours, you can resume normal activity in treated rooms. Continue using the mattress encasement.
- Continue monitoring for any new bites, faecal spots, or live bugs. Take photos if you see anything and send them to us before the follow-up visit.
- Avoid moving items from treated rooms to untreated rooms for the full 2 to 4 week post-treatment window. If you must move items, bag and heat-treat them first.
- Attend the scheduled follow-up visit. Our technician will inspect harbourage zones and confirm whether the infestation is broken or whether additional treatment is needed.

Frequently asked questions
Is it normal to see bites after treatment?
Bites in the first 1 to 2 weeks after treatment are usually from bugs that fed before the application and the bite reaction is delayed. This does not mean treatment failed. Bites after 3 weeks or new live bugs in treated rooms indicate that some eggs hatched and need follow-up treatment.
When can I wash the bedding again?
You can wash bedding 24 to 48 hours after treatment. Use hot water and high-heat drying. The encasement should stay on continuously for the full 12 to 18 month period regardless of washing.
What if I see one bug after treatment?
A single surviving bug does not mean failure. Take a photo, send it to us, and we will advise. In most cases a targeted spot treatment during the follow-up visit handles it without restarting the program.
Can I prevent bed bugs from coming back?
Yes. After clearance, the main prevention steps are inspecting luggage and soft furnishings after travel, avoiding second-hand soft furniture without heat treatment, using mattress encasements long-term, and being alert to early signs in high-turnover rental properties. We can advise on a monitoring plan for properties with recurring exposure (Airbnbs, hotels, service apartments).
