All treatments have their benefits. Surface and Aerosol sprays have a long residual effect and continue to work long after they're applied. Heat treatments can provide a quick knockdown of all activity in the premises. All methods have pros and cons so a tailored approach is always best.
Q: HOW LONG DO THEY LIVE?
The lifecycle lasts for about 65-90 days, with the female adult moths living for about 30 days and potentially laying up to 300 eggs. The larvae that hatch from the eggs do the damage, as the adult moths themselves, known as 'millers', pose no threat to your knitwear.
