CimeXa Dust Review

If you’ve made your way to this page you’re probably doing some search into CimeXa Dust and wondering if it’s a good fit for your pest control needs. Let’s take a deep dive into everything there is to know about CimeXa Dust in this review so you can know if you need it and how to best apply it.

What is CimeXa Dust?

CimeXa Dust is non-repellent, low-toxicity engineered silica dust. It’s a white, odorless powder that’s very fine and lightweight.

It shares some similarities with diatomaceous earth, but as we will find out it’s actually much more effective.

CimeXa is sold by the bottle or bucket, and can be applied as any other powder would be. Most people would use a duster for application but it can depend on your specific needs and application sites.

How Does CimeXa Work?

CimeXa Dust works at the physical level rather than chemical level. Bugs come into contact with it and the dust destroy’s exoskeleton by absorbing moisture and oils. This causes bugs to rapidly die from dehydration, often within 24 hours.

CimeXa does not repel bugs. You want bugs to come into contact with CimeXa because that’s how it kills the bugs. Often times bugs will carry CimeXa Dust on their exoskeleton and transfer it to other bugs they come into contact with giving it great effectiveness.

What Does CimeXa Dust Kill?

CimeXa Dust kills a wide variety of insects. Most any bug that crawls and has an exoskeleton, CimeXa will kill. This includes bed bugs, spiders, fleas, ticks, lice, roaches, ants, firebrats, silverfish, drywood termites, mites and more.

Most often, people turn to CimeXa when dealing with interior pests like bed bugs.

How to Use CimeXa Dust

CimeXa Dust is typically applied with a handheld duster around the desired treatment areas. For bed bugs, this means cracks and crevices of floorboards, baseboards, furniture, mattresses, box springs, and more.

You have to understand the biology of the bug you’re up against so you know which areas you need to effectively get the powder into in order to kill the population.

In order to spread the powder, most people use a handheld duster. A handheld duster gives you pretty good control over how much powder to apply at once, and also lets you really shoot into crevices that bugs may love to live in.

For more fine control of the dust, you can dip a dry paintbrush into some of the powder and brush it as needed. This can be very useful for applying to areas where a duster would be overkill.

Finally, CimeXa Dust can also be mixed with water at a concentration of 4 oz to 1 gallon, and sprayed from a sprayer.

How Effective is CimeXa Dust?

CimeXa Dust has been well studied on its’ bed bug killing ability and found to be extremely effective.

One study done in 2016 found that 100% of bed bugs continuously exposed to CimeXa Dust died in just 36 hours, compared to 14 days for bed bugs exposed to the more common and cheaper alternative, diatomaceous earth.

Another study done in 2017 found some results that were both good and bad for CimeXa.

The good: bed bugs that came into contact with CimeXa killed over 95% of bed bugs within 24 hours and had a 100% mortality rate after 4 days. This was better than any of the 5 alternatives tested.

The bad: bed bugs seemed resistant to travel onto the CimeXa Dust and spent less time on the dust than 3 of the alternative products. That being said, the 3 alternative products where bed bugs were much less likely to crawl on killed anywhere from 30-90% of the bed bugs after 4 days so they were less effective after contact was made.

The conclusion I would take away from this is CimeXa is still a great option to use, you just want to be sure to apply it where you suspect the bed bugs are living because eventually they’ll be forced to move across the dust to feed or find water, so death will be certain eventually.

How Safe is CimeXa Dust?

CimeXa Dust is classified as being low-toxicity. Relatively speaking, it’s safer than most chemical alternatives. There are no protective requirements for the product listed on the label, but you may want to use gloves, a mask, and goggles when applying it.

Getting CimeXa onto your skin would cause it to dry out, so it’s recommended you rinse it off if anything comes into contact. The dust would irritate your lungs and eyes if it came into contact, but there’s no other known issues or side effects of using CimeXa Dust.

CimeXa Dust is labelled for use around pet bedding areas, so it’s safe for homes with pets as well. It is not known to be a water pollutant, hazard to wildlife such as bees, birds, and fish, and not known to have any harmful effects to humans such as causing cancer or developmental issues.

Who Manufactures CimeXa Dust?

Rockwell Labs researches and manufactures pest control products in Kansas City. In 2012 they released CimeXa Dust, which has been found to be a big improvement over other popular dusts from bed bug control.
