Are bed bugs really a serious problem?

Bed bugs are on the rise all over the world, having increased 500 percent over the last three years in the U.S. alone. Pest control professionals report infestations in hotels, multi-family housing, apartments, and hospitals. Although mostly eradicated in the U.S. around World War II, the current resurgence is attributed to an increase in international travel and immigration combined with less frequent use of strong pest-killing products.

They hitch rides on luggage, backpacks, shoes, or any other mobile material. One may find them hiding in small cracks and crevices in human environments including along mattress seams, within box springs, bedsheets, nightstands, headboards, upholstered furniture, lamps, picture frames and luggage.

Bed bugs quickly move from one bed to another and prove especially difficult to control in hotels, apartments, dorms, or other buildings with a large number of beds. Bed bugs do not transmit diseases, but their bites can become red, itchy welts.

Are your mattress protectors fire retardant?

Our SofCover fabric received a "B" Classification to meet the American Standard ULV-O Burn Test requirements, which resists smoldering cigarettes. Our SofCover material was tested to CFR Title Part 1632 (FF4-72) Standard for the Flammability of Mattress and Mattress Pads – Ticking Substitution Procedure Part 1632.6. This federal mattress flammability standard requires that all mattress pads be cigarette-ignition resistant, effectively extinguishing three burning cigarettes before they burn the length of one inch.

Our KleenCover fabric received a "C" Classification.

Is there an MSDS for the ActiveGuard™?

Yes. Please see below. Also, please be aware that the incidence of any skin irritation is extremely rare. All reported incidences of irritation from permethrin over the past 30 years must be included in the reporting and required disclosure in the MSDS, regardless of the product.  ActiveGuard has been in use in Europe and Asia for the past 10 years and there are more than 100,000 liners in use.

Permethrin has been in use in military uniforms and outdoor clothing for decades and is in direct contact with the skin. 

The very few people that would be sensitive to permethrin would likely be sensitive to many other items like shampoos, conditioners, detergents and soaps.

What bed bug testing certifcation do you have?

Our Kleencover® and SofCover® materials in Superior, Ultimate styles have been independently tested by a board certified entymologist to offer reliable protection against both bed bug bite and escape. Our Boxspring Protectors also provide the necessary entrapment protection to keep bed bugs from getting in or out. Certification at this high a level required not only the right material, but also the patent pending zipper with "The Hook".

Testing was conducted with live bed bugs over a 4 week period to ensure effectiveness against not only bed bugs, but their unhatched eggs. To summarize, at the conclusion of the test period there were ZERO bed bug bites through the specially laminated material and ZERO bed bug escapes.  

To view or print the complete test results please see "Documents."

What is the difference between The Ultimate and The Superior since they are both Bed Bug Certified?

The "Ultimate" offers 6-sided waterproof and bed bug "bite-proof" protection and is available in specific depths to match the depth of your mattress: 9", 12", 15" and 18". If your mattress does NOT have pillow-top construction, warranty maintenance instructions may require you to both rotate and flip your mattress routinely - this can be accomplished with the Ultimate Mattress Encasement while remaining in quarentine. The "Superior" fully encases your mattress and provides waterproof and bite-proof protection on the top and along the side panels. A stretch-knit fabric is used along the bottom of the side panels and across the underside of the mattress allowing for penetration-and-escape proof protection and stretches to fit mattresses up to 18" in depth. If your mattress has a pillow-top construction, warranty maintenance instructions may include rotating , but not flipping your mattress periodically thus allowing for the option of the Superior.

Whether you choose The "Ultimate" or The "Superior" mattress encasements, we recommend encasing your box spring with the Stretch Knit Box Spring encasement and your pillows with the Pillow Safe encasements for complete protection and peace of mind.

ActiveGuardTM Dustmite and Asthma Atopic Dermatitis Research

ActiveGuard, under the name 'Z-net', is approved by the FDA as a Class I 510 (k) medical device.  Supportive clinical efficacy and safety data detailed within the published references below was germane to the issuance of marketing approval by the FDA. ActiveGuard Mattress Liners were invented by Philadelphian Sandra Shober and developed by a team of medical entomologists at the London School of Hygiene and Tropical Medicine. The product was introduced in Europe in the late 1990's and over 100,000 have been sold in Europe, Asia and the United States to kill dust mites for up to two years and to kill bed bugs in mattresses and box springs.

Why should someone use mattress protectors?

Our Superior and Ultimate mattress protectors save money, time and are effective. They.......

  • Protect and Salvage Your Expensive Investment In Bedding. A minimal investment in our mattress encasements can prevent the loss in the heavy cost to replace this value.
  • Address Early Detection of Infestation. By applying our mattress and box spring encasements before any signs of infestation, you will minimize the available areas to nest and lay eggs as well as provide the means for an easy detection of the presence of bed bugs.
  • Prevent Initial Infestation In Mattress and Box Springs. At least 70% of bed bugs colonize the mattress and infrastructure of the box springs. If there is an infestation, our encasement eliminates the opportunity for bed bugs to find a home.
  • Stop the Spreading of Bed Bugs. When trapped inside our encasement, bed bugs and hatchlings are subjected to starvation and prevented from escaping and spreading.
