Using products containing borate-based active ingredients such as Niban or Magnetic Roach bait with boric acid and Nibor-D with DOT will help prevent bait resistance, writes Jamel S. Sandidge, PhD, BCE, Innovation Platform Leader, Pest Management Systems Nisus Corporation.
There are three things I like to stress concerning resistance:
Rotate insecticide classes, not just products. Active ingredients from different insecticide classes will have entirely different modes of action and be more effective in controlling physiological resistance. Here are some examples of products you do not want to rotate that are in the same class:

To combat bait aversion carry a variety of baits from different manufacturers that will contain different base ingredients. Before applying the bait to the entire structure, offer a few smaller bait placement to cockroaches to see if there is apparent behavioral avoidance.
Between the lack of light and the amount of potential clutter, safety glasses are certainly the first thing you think of when assembling your PPE, says Billy Tesh, president of Crawlspace Depot.
That’s a good question! While you wouldn’t want to choose just a single safety item in reality, there is one you should put at the top of your list, and that’s safety glasses. It sounds like such a simple thing, but the consequences of not using safety glasses can be permanent and tragic. And when you’re closing crawl spaces, eye protection is absolutely imperative. It’s often hard to see and that makes the chances of running into something that can injure an eye much greater. Also, crawl spaces tend to be messy places with ductwork, nails, insulation and all sorts of other surprises that can cause significant injury. Between the lack of light and the amount of potential clutter, safety glasses are certainly the first thing you think of when assembling your PPE.
Unfortunately, no. Safety eyewear conforms to a higher standard of impact resistance. While regular prescription glasses obviously offer a barrier to everyday events in our regular lives, that’s not their purpose. They can’t qualify as occupational “safety glasses” unless they meet the safety eyewear standards established by the American National Standards Institute (ANSI). The ANSI standards are also used by Occupational Safety and Health Administration (OSHA).
The two kinds of safety glasses are prescription (available from an eye care professional) and non-prescription (“plano”) safety glasses, then there are two classifications of impact resistance: basic and high impact. The choice of impact level depends on your occupation, and some activities require even more protection, such as side shields, goggles or full face protection. Wrap styles are popular for any activity that might need a side shield.
Many styles are available depending on your needs and personal preferences. Options include padding, magnification, over-glasses fitting, anti-reflective (AR) coating, polarized lenses, various patterns and lens tints. Eye professionals can even prescribe bifocals and progressive lenses as well as standard prescriptions.
The lens material is also important. Many people prefer polycarbonate lenses because they weigh less than half than glass and are also more impact resistant. Unfortunately, they’re softer than glass, so they’re more easily scratched. Anyone who wears regular glasses is aware of this problem!
If you choose eyewear protection with the highest impact standard, you can’t go wrong in just about any occupation. For crawl space work, in particular, we also recommend non-polarized glasses because you don’t need polarized lenses in a crawl space as there is no sun to create glare and sun hazes. (You might opt to have anti-reflective lenses to help with glare from the artificial lighting in a closed area, but they aren’t a necessity.) Almost as important as impact resistance for practical working conditions are anti-fog lenses. When you get into a crawl space, you’ll probably find your glasses fog up the minute you put them on! It’s not only frustrating, it’s dangerous.
Because we offer quality materials to close crawl spaces and we felt this issue was so critical, we now offer products from Edge Safety Eyewear. Edge takes pride in merging cutting-edge technology with contemporary fashion, providing the finest safety-rated eyewear on the market. They not only offer the best impact protection, but also premium anti-fog protection with their revolutionary Vapor Shield technology.
Edge’s impact resistance is phenomenal. It’s tested in independent laboratories for compliance with both ANSI Z87.1+2015 and Military Ballistic MCEPS GL-PD 10-12 – in fact Military Ballistic MCEPS safety standards simulate a shotgun blast from 33 feet!
Many Edge Eyewear models feature their unique Vapor Shield Anti-Fog technology. It’s so common to see technicians in a crawl space with glasses so fogged up that they can’t see. No matter how many times they stop to clean them, they just fog up again. So what happens? They remove the glasses and keep working! That’s a critical problem that now has an easy fix. This isn’t your Grandpa’s standard anti-fog. It’s a special application that is absolutely impervious to fog and recommended for “extreme” environments — like a crawl space!
In addition to their superior impact resistance and available Vapor Shield models, Edge has a wide variety of styles to suit individual tastes and fits — everything from lens tints to goggle kits. Edge offers unique features to fit the specific needs of different work environments and various facial structures. Their glasses also provide 99.9% UVA/UVB/UVC protection. We feel that adding quality safety products like Edge Eyewear helps complete our crawl space product line.
The Edge Caraz Safety Glasses feature clear lenses for optimal clarity plus an EVA foam gasket ideal when working in environments with high levels of airborne debris, dust or wind. The arms detach so that you can attach an adjustable head band to keep the glasses secured to your head regardless of your orientation.
The Edge Brazeau-Torque, Khor G2 and Dakura Safety Glasses are all designed to fit comfortably with a stylish look. The Brazeau and Khor G2 feature clear lenses with pristine clarity, so they are an excellent safety choice for indoor and low light conditions. The Dakura’s yellow tint provides slightly less light transmission than clear lenses when light is present, but items appear with more clarity. Technicians really like using these in a crawl space environment.
Cockroaches and infestations of these insects were the impetus for the birth of the pest management industry. Dr. Janis Reed, BCE, Technical Services Manager with Control Solutions, Inc. (CSI) answers some questions on cockroaches and cockroach infestations.
Cockroaches need 4 things to survive: food, water, harborage, and procreation. In my opinion, harborage removal/elimination is key for cockroach control. Typically, this means cleaning clutter, and then treating any remaining harborage.
Baits are popular because of their simplicity and overall effectiveness. In general, they have been so successful because of three things:
This can be boiled down to one word: Reproduction. Cockroaches’ ability to reproduce quickly is why they are successful. German cockroach females typically develop in less than three months from egg to adult. This generation time means cockroach populations can build rapidly. Additionally, a single German cockroach female can produce 40+ eggs per ootheca and she can make several of these egg cases in her lifetime.
Cockroaches commonly affect human health in two ways: allergens and spread of bacteria.
Cockroach cast skins (exuviae) and fecal material contain proteins that many people can be allergic to. If exposed for long periods of time or repeatedly, this can cause serious medical conditions, including asthma.
In food-preparation areas, cockroaches can physically move bacteria on their bodies. For example, the cockroach may be spending time in a sewer and then crawl across a clean kitchen counter, bringing dangerous bacteria with them in the process.
Cockroaches play a very important role as nutrient recyclers and detritivores (organisms that eat decaying organic material). When cockroaches feed, they help to replenish nitrogen in soil. This, in turn, feeds plants. If we had no more cockroaches, the effects on plants, soil and forests would be disastrous. While cockroaches are not welcome in our structures, they are beneficial insects in the natural world.
