Ultra Low Volume is a fumigation method from what I can google up.

ULV stands for Ultra Low Volume and in essence is the same as the less used ULD ultra low dose. It is the current method of space spray (fogging, bombing) which applies a material to aspace. It is also referred to as micro gen as the particles are in the 5-15 micron range. It is better than older types of fogging as due to particle size they can waft around like cigarette smoke or natural fog riding air current. Due to the application method structural applications are almost always of a non residual nature, in other words contact kill. You must be careful with pilot lights and other similar issues. All people and pets must be out of the area which needs to be vented prior to re entry. Fumigation on the other hand utilizes gases that can penetrate into cracks and void areas. Fumigants are deadly gases and must be used by trained professionals.

ULV applications, for the most part, will not be effective for bed bugs. In certain situations (treating a wall void for instance) it may hold some value but to use ULV to treat for bed bugs will typically not get rid of your problem.

Oh yeah got carried away and missed the forest from the chainsaws. ULV is with few exceptions not a recommended tool for bed bugs same as bombs. We also have learned better tactics with roaches and a number of other pests. However in food processing and some other areas they are still vital tools.
