k, i work for a pest control company, and for $150 we can treat the house, 2 step
process done 10 days a part, or...

you can go to "do it yourself pest control" and get a 2 cans of Ultracide
1-Vacum and mop well first
2-pull all the pillows off chairs and sofa
3-Just spray in a sweeping motion, start at the back of the house and work towards the door. (you have to be gone couple of hours after)
you have to get all the crack and crevices of all the furniture as well as at the baseboards. Spray everything, carpet, hardwood floors, ceramic, whatever. Pets bedding also. Pay attention to the legs of the furniture.
Won't take long at all.
4- vacum EVERYDAY (if it is a canister, dump it into a ziplock and take to the trash outside, if it is a bag, throw it away every other day)
5- 10 days later, do it again and keep the vacuming up for 10 more days after that.

One can should do it per treatment unless you have more than 2000 sq ft.
then you will be good to go... gl

P.S. if you have birds, fish, snakes, or lizards in the house lmk, i will tell you what to do with them before you treat
