Moth bombs

[yaki]

No more Mr Nice Guy ! Look online for fumigation smoke bombs . Like a egg sized firework. You light a tab some sparks then it let's out a plume of fumigating smoke.
Open all wardrobes and drawers, close windows and doors , a towel around door bottom. Leave for a few hours.
Theres is also a spray to use from thd same supplier for residual effect
Toxic no doubt but its far better than cedar balls etc.

Before that empty all clothes storage, hoover and clear. If carpet, then a very thorough vacuum everywhere, in, under and behind! Then spray. If your issue is that bad, get a professional in to use the good 'stuff'. Then repeat! No used clothing in wardrobes as this attracts them too.
