Bug Bomb crawl space Help Me Please

I am having a bug problem with roaches, ants, ect...

I think it would be a good idea to release a bug bomb in the crawl space. I think it would be eaiser & more effective to bomb.

I have never done this before & was wondering what I need to do. For example, what about the chemical that will collect on the furnace & culligan unit? My drinking water goes through the unit.

House is brick & fairly tight where does the chemical Ventilate?

How much chemical will make it into the house from the crawl space?

What should I do?

single level 1200 sq house. I have a storm cellar which connects to the crawl space under the kitchen and a portion of the living room. The cellar is brick and concrete and connects to a slab with half walls opening up under the house. On the slab sits the utilities: water heater, furnace, and culligan unit.

also about spraying the house. I have never does this.

What I would like to do is spray in the gap of my storm windows & around my base boards.

Will the chemical damage my home? The wood frame of the storm windows? Or the hard wood floors of the home?

What about making the dog sick. She always runs around the kitchen when we are cooking and sniffs.

What about the chemical odor in the house?
