Orange Guard Home Pest Control: Caution[1]

Contact spray first, repellent second

The label sells Orange Guard as a contact killer, so the spray has to wet the insects or their hiding spots to work. It also claims the treated area keeps repelling insects for weeks.[1]

For fleas, the directions call for treating pet bedding. The label does not give directions for spraying the pet itself.[1]

Where it is used

Indoors, spray insects directly from 8 to 12 inches away and saturate the area until visibly wet. Use the stream setting on roaches and to reach into cracks and crevices.[1]

Treat kitchens, pantries and the spaces under cabinets and appliances where insects hide. Wait three minutes, then wipe up the excess with a damp sponge or cloth.[1]

Outdoors, spray the home's perimeter generously to form a barrier, plus doorways, window frames and cracks where insects get in.[1]

Saturate ant trails and nests, and spray garbage cans, manure piles or other infested spots until they are visibly wet.[1]
