suspected of being infested are stored. Prior to spraying, remove all foodstuffs, shelving paper and utensils.

packages should be destroyed.

Wasps (Outdoor): Apply Orthene PCO Pellets as a spot application at 0.5% to 1.0% to the nest, nest
entrance and surrounding areas where the wasps alight. Wasps are generally less active early and late in the
day, so it is advisable that nests should be treated during these times. Do not apply with low pressure handwand equipment.

Ants, Fire and Harvester (excluding carpenter and pharaoh ants) in mounds within a treated
perimeter – In order to control a mound or nest, a drench treatment is necessary. For mound drench
treatment, dissolve 1 packet (1.4 oz.) of Orthene PCO Pellets in 9 gals. of water. Apply 1 gal. of mix to
each mound by sprinkling the mound until it is wet and treat a 4 ft. diameter circle around the mound.
For best results, apply Orthene PCO Pellets in the early morning or late afternoon when ants are most
active. Mound drench applications made under prolonged hot and dry conditions may be ineffective due to
the location of ants deep within the nest.

NOTE: Grass in treated areas may be injured. DO NOT treat a mound more than once per season.

moderate pressures (up to 35 psi) using a coarse fan tip. For spot treatments, no individual spot will exceed
