This chemical solution effectively kills indoor and outdoor insects in as fast as 24 hours.

Discovered centuries ago, bed bugs are nocturnal parasites that feed on human and animal blood [1]. These insects can live for months even without feeding on blood. Once they have found a food source, bed bugs will continuously feed on their host and reproduce.

If you’ve already tried everything and the home remedies to get rid of bed bugs didn’t work, another alternative is a chemical treatment like the Ortho Home Defense Insect Killer. This chemical solution effectively kills indoor and outdoor insects in as fast as 24 hours. 

What is Ortho Home Defense?

Ortho Home Defense is a chemical product designed to kill insects that invade homes, from ants to bed bugs. The solution contains an active ingredient that can kill pyrethroid-resistant bed bugs and their eggs, which are the most difficult to eradicate.

Through Ortho Home Defense, you can ensure that your home is protected from insect infestation by spot treating the areas they hide in, such as bed frames, mattresses, baseboards, cracks, and crevices. Also, it doesn’t only eradicate insect problems but acts as a barrier to keep them out of your home. 

What’s the Active Ingredient in This Bed Bug Killer?

What's the Active Ingredient in This Bed Bug Killer?

Ortho Home Defense contains Bifenthrin. This active ingredient is a neurotoxin and insecticide, directly affecting insects’ nervous systems and killing them. In short, once bed bugs get in contact with Bifenthrin, they will eventually die. 

While bed bugs don’t spread disease to humans, their bites are irritating and itchy, which may cause insomnia or lack of sleep [2]. This means that eradicating your bed bug problem is necessary before it worsens.

If you’ve tried many solutions to get rid of bed bugs and none of them works, the Ortho Home Defense is very efficient as it contains a generous amount of Bifenthrin.

How To Use It

If you’re to treat a bed bug problem or eliminate insects infesting your home, follow the steps below on how to use Ortho Home Defense indoors:

  • Identify the infected areas.
  • Shake the product well before applying.
  • Place the spray nozzle into an indoor setting.
  • Hold the sprayer 12 inches from the surfaces needed to be treated.
  • Apply the product in a 4-inch band in the interior of your home, where insects are commonly found.
  • Spray the product until slightly wet but not soaking. 

For outdoor application, follow the steps above but apply a 12-inch band on the exterior perimeter of your home, especially on areas where insects are commonly found.

Yes, Ortho Home Defense is effective as it contains an active chemical that instantly kills insects. However, the product’s effect may vary depending on what type of insect you’re trying to eliminate. In addition, the proper application should be considered since it can affect the product’s efficacy.

If you’re applying the product a bit far away from infected areas, it may not completely kill insects. Temperature and weather should also be considered during application as they can lessen the effect of the chemical once diluted by rain or burned by direct sunlight.
