What Active Ingredients are in Ortho Home Defense Bed Bug Killer and How Do They Work?
The active ingredients in Ortho Home Defense Bed Bug Killer are designed to effectively target and eliminate bed bugs and their eggs.
- Bifenthrin: A synthetic pyrethroid, bifenthrin disrupts the normal functioning of the nervous system in insects.
- Imidacloprid: This neonicotinoid insecticide acts on the insect’s nervous system, causing paralysis and death, especially in pests like bed bugs.
- Prallethrin: Another synthetic pyrethroid, prallethrin has a quick knockdown effect on bed bugs, rapidly incapacitating them upon contact.
Bifenthrin: Bifenthrin is commonly used in pest control due to its effectiveness against a wide range of insects. It works by binding to sodium channels in the insect’s nerve cells, leading to uncontrolled firing of nerves, eventually resulting in death. This ingredient is particularly valued for its residual activity, which allows for prolonged protection against bed bug infestations.
Imidacloprid: Imidacloprid is effective at targeting the nicotinic acetylcholine receptors in the insect’s nervous system. By mimicking the action of neurotransmitters, it causes continuous stimulation of the nerves, leading to paralysis and death. Its systemic action means it can affect pests that come into contact with or ingest the treated surfaces, making it a powerful component in bed bug extermination.
Prallethrin: Prallethrin is known for its rapid action, providing immediate knockdown of bed bugs upon contact. It works similarly to bifenthrin in disrupting the insect’s nervous system but is often used in combination with other active ingredients for enhanced efficacy. This ingredient is particularly effective in areas where quick results are necessary, such as in homes experiencing a sudden bed bug infestation.

How Should You Properly Apply Ortho Home Defense Bed Bug Killer?
To properly apply Ortho Home Defense Bed Bug Killer, follow these essential steps:
- Preparation: Begin by removing all bedding, linens, and clutter from the infested area to ensure the treatment reaches all hiding spots.
- Application: Shake the bottle well and apply the product evenly along baseboards, carpets, and any other areas where bed bugs might reside.
- Targeted Treatment: Focus on cracks, crevices, and other potential hiding places such as furniture joints, bed frames, and behind headboards.
- Follow-Up: Allow the treated areas to dry completely before reintroducing bedding and personal items, and consider a follow-up treatment after 14 days for best results.
Preparation is crucial in ensuring that the bed bug killer can effectively reach the pests. Remove bedding and clear the area of any items that could obstruct the treatment process, as this allows for thorough coverage and minimizes the chances of bugs escaping the pesticide.
During application, it is important to shake the bottle thoroughly to mix the contents properly. Apply the product in a systematic manner, covering all surfaces where bed bugs may hide, as this increases the chances of encountering them and reduces the risk of re-infestation.
Targeted treatment is essential as bed bugs tend to hide in small spaces. Direct the spray into cracks, seams, and crevices where bed bugs are likely to be found, ensuring that you treat the bed frame, mattress seams, and any furniture in close proximity to the bed.
After applying the product, allow it to dry completely, which helps maximize its effectiveness. Re-introduce bedding only after the treated areas are dry, and plan for a follow-up treatment two weeks later to address any newly hatched bed bugs that may not have been affected by the initial application.
