Frequently Asked Questions

Select a question below to find the answer

Who makes PROOF®?

Proof was developed and is made by Terramera PlantScience in Washington state. Terramera is dedicated to creating plant based bio-pesticides that are non-toxic and are more effective than synthetic chemical pesticides.

What is PROOF?

PROOF is a plant-based bed bug spray that leverages the natural defences of the neem plant to kill 100% of bed bugs and their eggs.

How is PROOF different or better?

It is the only EPA-approved product that kills 100% of bed bugs and eggs and keeps working for weeks. (Including hidden pests, and pesticide-resistant bed bugs and eggs).

What do you mean by 100% Effective?

In scientific studies conducted by independent labs, PROOF killed 100% of bed bugs and bed bug eggs that were sprayed directly. In these studies, PROOF even killed 100% of bed bugs and their eggs that were not sprayed directly but were only exposed to surfaces treated with PROOF.

Why do I need PROOF?

Bed bugs are now in every state in America with 67% of pest control professionals having treated hotels or motels for bed bugs. US travellers abroad are even more likely to come into contact with these pests. If you travel, you need PROOF 100% Effective Bed Bug Protection.

What if I already have Bed Bugs?

PROOF kills bed bugs and eggs. The 3oz spray is packaged to help you prevent bringing them home. If you already have an infestation, bed bugs are a tough pest to get rid of and will need many bottles of this stuff.

Contact us and we’ll help you find someone reliable.

Where can I use PROOF?

PROOF can be used on a variety of indoor surfaces, fabrics and materials including suitcases, travel bags, box springs, mattresses, linens, under and around beds, bed frames, headboards, night stands, curtains, blinds, carpets, rugs, and upholstery and anywhere bed bugs hide or their eggs may be found.

How long will PROOF work?

When used as directed, PROOF will continue to kill bed bugs for up to 2 weeks and bed bug eggs for up to three weeks.

What’s wrong with unregulated natural products?

Unregulated products have not been scrutinized for safety or effectiveness by the Environmental Protection Agency. Product claims are similarly unsubstantiated.

Can I spray PROOF directly on clothes and luggage?

When using PROOF, we recommend spraying both the inside and outside of your suitcase to give maximum protection. You should spray until the surface is damp, but not wet. Let the surface you spray dry before placing your clothes inside the bag.

We have sprayed PROOF on clothing and this does provide added protection but can cause mild staining on some fabrics, so please do a test spray first. We have not had any issues with staining on clothing that has contact with surfaces where the PROOF that has dried before contacting the clothing.

Regarding the safety of exposure to skin, we have not seen any issues with this. The active ingredient we use in Proof is organic Cold Pressed Neem oil. All other ingredients in PROOF are food grade. In developing Proof, we use the only EPA registered cold pressed neem oil. This is the purest and highest quality of unmodified neem oil. Neem oil has a long history of safe use in products like cosmetics, soaps, shampoos, toothpaste and skin lotions. There are many neem based toothpaste or skin products currently available in retail organic stores.
