Cedar Oil Pest Control

Wondercide BioDefense® is made of organic Cedar Oil and Hydrated Silica which dissolves the insect eggs and larvae. This eliminates the next cycle of insects from hatching. The aroma of cedar repels insects too, causing a pheromone interruption (only insects have these) and a flight response.  This means that insects will leave or be repelled by treated areas.

BioDefense Information Sheet


How Long Does it Last?

Like any pest control objective, it depends on the insect or parasite. For prevention & maintenance, this is the best cedar oil pest control on the market. Spray under sinks, in pantry, closets, bathroom, laundry room, cracks & crevices or anywhere insects reside. Spray around windows and doors. With routine outdoor treatment using Wondercide EcoTreat™, BioDefense® will protect indoors for 3-6 months or longer.



For parasite (flea, tick, bed bug, mite) control, use BioDefense® in a compression sprayer or ULV, Non Thermal, Tri Jet Fogger to eliminate the adult insects and the egg layer life cycle. You must treat all areas in the home and lawn to eliminate an infestation.   
Use often on pet beds and carpet to knock down the flea life cycle as your pet comes and goes from inside.  It's not harmful so you can't use too much. Approved for everyday use.

How Does BioDefense® compare to Chemical Pesticides?

It doesn't. Chemical-based treatments utilize water or petroleum distillates as a carrier for their active ingredients, most often Permethrins, or other formulations using primitive, nerve gas byproducts, commonly referred to as Pyrethroids. Wondercide's BioDefense formulation combines its proprietary cedar oil blend of Texas Red Cedar and a carrier created from melted quartz. Combined, these two ingredients create a new molecule that has superior penetration abilities, and provides instant kill to fleas, ticks, mites and bed bugs. Compared to chemical products, BioDefense provides instant death with a mortality rate that approaches 100% within seconds, by causing an immediate, systemic metabolic reaction that triggers a suffocation response in parasites. Cedar oil pest control is a biological, not chemical pest control.

For Best Results

Home owners can easily do it yourself with a hand held compression sprayer or by using a non thermal ULV fogger, available through Wondercide. The ultimate in flea, tick, mite & bed bug eradication is fogging with 1 gallon of BioDefense® per 1,500 sqft. Depending on the severity of infestation, additional treatment(s) may be required.  This product is safe for everyday use. If you have indoor - outdoor pets, consider using BioDefense® as an ongoing flea control preventative on pet beds, furniture & floors. Natural Cedar oil pest control is safe and effective.

Customer Reviews

  •   We are so amazed

    We tried every bomb, powder, and spray we could find and nothing worked. We've had a flea battle for a couple of years. I heard a radio ad about this and had to try it. We rented the fogger and bought 2 gallons of Biodefense. Our problem is history. We are so amazed and so thankful to have our lives back.

  •   Thanks!

    So happy to use a safe product that works! I was always worried about flea bombing our basement since the kids and the cats spend a lot of time down there but not anymore! Got rid of the fleas and we have happy cats again!

  •   Call me the Brown Recluse Killer :)

    I did some research with biodefense and brown recluses. I found a small spider and he stopped moving in about 15-20 seconds, was curled up in a ball and completely dead in about 45. Caught a good sized BR by the side of my house where I think they have been nesting in the basement window wells, that one took a good minute to die, but he was a tank. It definitely kills them and since I've been using it, I don't really see them around anymore. Good Stuff.

  •   I still can't believe how fast this works

    It had a strong smell at first but it went away in a few hours. We had fleas in our apartment and tried this smaller size before we spent money on the gallon (my husband was hesitant). It killed the fleas and we were so excited that we bought the gallon to finish spraying everything! I still can't believe how fast this works and how safe it is for our family. Many thanks from San Diego!

What's the difference between cedar and lemongrass?

For most Wondercide products, we offer various fragrance options. The most common Wondercide fragrances are lemongrass and cedar.

For Wondercide pest control products all products, no matter the fragrance, contain the same active ingredient—cedar oil. Cedar oil is what repels insects and makes our products effective.

No matter what fragrance you choose, your pest control product will contain 10% cedar oil. Since each product contains the same amount of cedar oil, all fragrances are equally effective at repelling and killing insects.

Why do we offer different fragrances?

We offer lemongrass and cedar fragrances merely to cater to different personal preferences. Oh, the freedom of choice!

Some people dislike the smell of cedar, and the lemongrass fragrance helps to lessen the cedar scent.

Most customers report that the lemongrass products smell “less strong” than the cedar options, and that the smell dissipates more quickly after spraying. However, not all customers can smell the difference.
