We've had moths for a year in a 3-bed house. I notice ten or twenty of the fat blisters hanging about on the walls every night when I go to bed in our bedrooms at the mo. Don't know where they're coming from. They appeared when DH decided to reorganise all our books during Lockdown 1. We got Rentokil round today to quote for getting rid of them. They quoted £5.5k for five fumigation sprays, which have to happen once a week and we have to stay out for four hours minimum afterwards. Doesn't sound very safe. On the fourth week, they bring their 'heat pod', which all our clothes (family of 4), duvets, sheets, go into and it heats them to 60 degrees centigrade, for an hour.
I know moths are tenacious little bastards. But am I being unreasonable to think there must be a cheaper/less toxic way? NO - I have solved this problem without emptying my bank account and spraying my house with neurotoxins, here's how; YES - This is the only way, I speak from bitter experience.
