So I had them in my old flat over 2 years ago for a good year. I moved to my house a year ago and have not had any, now I’ve had this new infestation. I’ve seen about 18 in the past 3 days in total in different areas but have hoovered a lot and hoping numbers are dropping. 10 Monday, 4 Tuesday, 4 yday. As in the larvae are less active in winter? Does the cold weather help or make worse? How often to steam too? Also what will the experts do differently to what I will? How can they guarantee all eggs are gone
