Ortho Home Defense Insect Killer for Lawn & Landscape Ready-To-Spray

Ortho Home Defense Insect Killer for Lawn & Landscape - Common Insects Treated

Ants

Fleas

Ticks

Spiders

Ants

Ants are common pests throughout the world. They are a nuisance, largely because of the annoyance caused by their presence - constructing mounds in the lawn or invading the home from the yard in search of food.

Fleas

Adult fleas are no larger than 1/8 inch long. They are reddish-brown, wingless insects that are laterally compressed, so they look as if they are walking on edge.

Ticks

Although ticks are commonly thought of as insects, they are actually arachnids like spiders and mites. They have 4 pairs of legs and no antennae. They lie in wait for a passing deer, pet, or person to walk near the shrub or grass they are perched on.

Spiders

Spiders can be found throughout the country. If you have the occasional fly or gnat in the house, chances are you’ll also have spiders in the house. Spiders live on bugs, but not enough to be considered for pest control.

Chinch Bugs

Cutworms

Mole Crickets

Sod Webworms

Chinch Bugs

Adult chinch bugs are about one-fifth of an inch long and black with white wings folded over their backs. Chinch bugs feed on many kinds of lawn grasses, but St. Augustine grass and Zoysia grass are favorites.

Cutworms

If you see spots of brown grass and birds pecking at your lawn, you could be facing a cutworm infestation.

Mole Crickets

Mole crickets can be twice as long as their singing cousins - and their tunneling can ruin your lawn.

Sod Webworms

Sod webworms are the larvae of lawn moths. They live in the root level of your lawn and munch up the grass leaves. At root level, you’ll see small white tubes made of silky web. At dusk, you might even see the worms themselves.

Fast Action & Effective Insect Killer
5 Stars
Fast Action & Effective Insect Killer
The Ortho Ant and Insect Killer is a fast-action and efficient solution towards killing insects.I had (past tense now) a massive ant invasion in my basement's boiler and hot water heater room for the past few weeks that grew worse over time. The ants dug up holes and mounds of sand first by the hot water heater, then the boiler. They were having a party convention of sorts! I purchased the Ortho (granular version) last week, and it arrived yesterday. I immediately applied a portion towards the hot water heater first, within a half-hour, a motherload of ants, now including the queen ants with the wings, started coming up from the holes and sand running around berserk! I applied a lot more Orthro to the sand areas. Within one hour, all the ants were dead, except a few stragglers.I understand that this product is intended for outdoors, but you may need to wear a mask when around this product if you have indoor basement insects as I did. The collective smell of this product is not for the human respiratory system.Check out my video for evidence that if you have ant and insect problems, this is the product to get!
