According to the
product label,
Catalyst can only be used indoors and cannot be used in residential structures at all. We do not think
Catalyst would be an appropriate choice for you.
Orthene PCO pellets can be used indoors and outdoors for roach control. When using Orthene outdoors for roach control, it is only
labeled to be sprayed to a band of soil 6 to 10 feet adjacent to the structure, also to a height of 2 to 3 feet on the foundation where pests may be active or may find entrance. Orthene PCO cannot be sprayed out in the yard.
