A very poor experience with this company. Paid 421 for cockroach treatment which supposedly came with a 3 month guarantee. The technician visited and sprayed. A week later and still no discernible difference. Other companies provide spray, bait and traps for literally half the cost. I found the company unwilling to discuss the effectiveness of their treatment or provide any follow up advice or support. I have since decided to give up on them and use another company. Have telephoned today requesting cancellation of a future appointment and refund. Company has been purposely difficult and obstructive. Would definitely never use again. Avoid.
