You should seal the house tight by closing windows and turning off ventilation ( heat or A/C). Then remove any animals from the house and put all food away in cupbboards. Place a newspaper under each bug bomb and try to have one bug bomb per room.
Seal up all food containers or put them in the fridge. Have all closets, cabinets, and doors open so that bug killing chemicals can reach those areas. Have your pets outside.
Remove all food, or put it in the refrigerator. Remove all pets and people from the house. Check the label for more specific details. Follow directions carefully.
Prepare to stay off-site overnight; take pets with you; put open food containers in refrigerator; make airtight seal as much as possible; budget two hours for thorough cleanup afterward.
