Greenmethods.com is a biocontrol shop that hosts a ton of information about typical greenhouse/indoor plant pests online to help you identify what pest you have and options for getting ride of it. If you have a greenhouse, they offer biological solutions for you and help you do it right. Carol Ford (Deep Winter Greenhouses) offers this sage advice: prevention is cheapest and best option - do not bring anything from the outside indoors, such as plants or tools that were used outdoors. While there's natural predator checks on outdoor populations, there's nothing like that indoors.
