I plan on moving to an new apartment in a couple of weeks. I checked on my furniture today and saw a lot of spiders and spider webs all inside the storage unit. I wrapped my mattress and pillows, but not the couches or chairs. I'm worried that spiders might be living inside of the couches. I want to use Raid Fumigator I'm the storage unit twice on the day I move into my apartment so I won't move any spiders in also. Is fumigating the storage unit the best option besides getting an exterminator?
