better at night

hi, I bought a sofa (floor model) at a big furniture store…got home; wash it down,vacuum it and found a little pet hair;  about 2 weeks later i just started getting ichy on the arm and legs(don’t know if it is all in my head as i am dark skin and i don’t see any bumps) so today i decide to do some deeper vacuuming and find some animal hair and i don’t have pets.and i don’t know how to go about checking for fleas? please can u help me?
