#2: My Detailed Review

1. Ultra-fast-acting formula

Ortho Home Defense Dual-Action has a quick knock-down effect (kills within minutes) against bed bugs and other crawling insects – and thus it can be classified as an ultra-fast-acting insecticide.

The insecticide is both a contact-killing and spot treatment formula. Therefore, this will ensure that the bed bugs won’t come back to your living spaces.

However, Ortho Home Defense has high potency which means that it might not be very safe around kids or pets. Therefore, you must clean the sprayed areas sometime after treating your home for bed bugs.

2. Odorless and Non-staining on clothes and Furniture

Ortho Home Defense will be safe to use on your furniture since it will not damage or stain the finishes for the furniture in your home.

Further, the spray may be considered odorless but has a little smell that most humans and pets will not find to be irritating. Also, it comes in both travel and regular sizes that are convenient.

Despite being super powerful against household bed bugs, this spray won’t have a negative effect on the environment including producing dangerous fumes.

However, some fabrics or clothes might not be compatible with this spray and thus you might need to undertake some cleaning after bed bug treatment.

3. Exterminates even Pesticide-Resistant Bed bugs

If you’re dealing with bed bugs that have developed immunity against various pesticides (like noted by National Geographic), then Ortho Home Defense is an excellent solution for you. 

From the onset, Ortho comes out as a highly reliable manufacturer of pest control solutions. Equally, this roach spray brand will kill even stink bugs, dust mites, and fleas.  

#3: My Experience:

1. Is Ortho Home Defense kid and pet Safe? 

Ortho Home Defense and its active ingredients are EPA-registered and are thus safe to use around for yourself, your kids and pest such as cats and dogs. However, don’t use it around aquatic life like fish. 

However, I actually haven’t experienced many people who’ve been poisoned by Ortho Home Defense. However, realize that deltamethrin may be neurotoxic or irritate your skin. 

I found this spray great for safely treating covering of the traveling luggage as a spot treatment. Further, it’s safe for treating mattress seams, furniture, and carpets.

In summary, Ortho Home Defense will be safe to use around your kids and pets, but you must not use it near aquatic life like fish. 

2. Has a 2-weeks residue effect

Ortho Home Defense (dual-action) has a long residue effect of about 2 weeks. Further, some other customers note that this spray formula will have 7-10 days or residue effect. 

However, the manufacturer also recommends that you spray regularly. For example, Ortho states that you begin with the daily application before going to 2-3 times spraying per week. 

Finally, you can now spray weekly or once every 2 weeks. Therefore, you can use the bed bug spray to both protect and kill the pesky pests.
