before starting clean/disenfect the area. make sure you have good air circulation. it should be pretty obvious if pests are there (sun leaves looking chewed on, ect)
On top of making sure everything is clean before you start DONT BUY SHIT POTTING SOIL,ive found all kinds of shit in junk no name brand potting soil,you name it ive found it in cheap soil,make sure the soil you use has been steralized.
Try not to touch other plants and if you end up doing so, change your clothes before going into your grow area. If you're really worried, maybe you can put sticky traps on the floor of your grow closet., but those things are tiny and they'll probably find a way to get in regardless. Where will the grow be...bedroom? If it's not in an area where people are constantly around, maybe you can use this: ProZap Insect Guard | Pest Control
