I sent him photos as I didn't know what I was dealing with. He said
You wont get rid of these with cleaning and shop bought sprays I'm afraid. You will need at least two professional treatments to get on top of this.
In response to your questions;
How far apart are the two visits? We aim for 7-10 days apart. Do you pay in one go? Ideally yes, we require upfront payment via credit/debit card, however, if budget is tight you can pay for one treatment at a time but please remember that you will need to complete the treatment program for it to be affective.
What's actually involved? – The textile pests detected on site requires a course of insecticide treatments, our highly trained technician will apply a water-based insecticide to the carpets in the affected areas. The technician will follow up with an additional two treatments (7-10 days apart) to break the breeding cycle and gain control of the pests. Please note that the treated areas will need to be vacated for a minimum of 3 hours after each treatment.
Please ensure that all carpeted areas are thoroughly hoovered, paying particular attention to beneath furniture and the edges of the rooms, prior to each treatment. Regular hoovering, including beneath furniture and the edges of the rooms, will help to maintain control of the pests and prevent the level of activity reaching its current levels in the future. Where possible, all clothing in the effected rooms should be either washed on a hot wash above 55 degrees, chemically dry cleaned, heat treated, or placed in a freezer for a minimum of 48 hours.
We can do weekend visits but it’s an extra £75 per visit, so we try and do it Mon-Fri between 8am & 4pm. You will need to vacate for 3 hours.
The technicians do have a sign written van I’m afraid. This is obviously a concern for many people, however, please remember that most people use us at some point in their lives and we do a wide range of pests including woodworm so nobody really knows what you are having treated.
