All About Contact Killers
TERRO® Contact Killers
For immediate knock-down of ants, spiders, wasps, hornets, stink bugs and other unwanted insects, TERRO® offers a variety of spray, granular and dust products that kill pests on contact. Most of these contact killers also provide long-lasting residual control.
TERRO® aerosol sprays with Pyrethrin and Permethrin provide dual protection against insects. Pyrethrin spray provides instant knockdown and Permethrin spray delivers long-lasting residual protection for up to 12 weeks. TERRO® contact killer ant and spider sprays can be used as a general surface, spot or crack and crevice treatment to all non-food areas where insects crawl and hide. Spray on trails, nests and points of entry to kill pests on contact and provide residual insect control. When possible, spray directly on the pests.
TERRO® Ant Dust contains Deltamethrin, an insecticide that kills insects on contact and through digestion. The Deltamethrin rapidly paralyzes the insect’s nervous system, providing a quick knockdown effect. The Ant Dust kills ants (including fire ants and carpenter ants), boxelder bugs, cockroaches, crickets, firebrats, spiders, ticks, wasps, silverfish and other insects on contact, and provides long-lasting protection up to eight months.
The powerful insect killer granules in TERRO® Ant Killer Plus kill pests on contact and provide long-lasting residual repellency. Use the granules as a perimeter treatment around the foundation of your house to keep ants, cockroaches, fleas and other insects from entering your home.
Expert Contact Killer Tips
Use TERRO® spray, granular or dust contact killers with long-lasting residual control to create a barrier around your house. Scout out insect infiltration hot spots around the perimeter of your home. Check the foundation for cracks, gaps and holes. Look around windows, gutters, dryer vents and AC units.
Inspect Your Yard
Spiders are often found in woodpiles, heaps of dead leaves or anywhere debris builds up. Use a TERRO® aerosol spider killer and spray these areas. In addition to spraying, removing debris around your home will lessen the possibility of any unwanted guests coming in.
Wasp's Nests: Know When to Spray
To reduce the chance of getting stung, the best time to spray a wasp or hornet nest is at dusk or dawn, when the insects are least active. After spraying the nest, wait at least 24 hours before removing the nest.
Outdoor Spraying Tips
When using TERRO® spray contact killers outdoors, be sure to point the spray nozzle away from your face, holding the can on a slight downward angle. Spray infested surface, spraying as many insects as possible. For best results, spray when the air is calm.
