Do You Find Me Repellent?
Do pyrethroids repel bugs away? I have heard that, in some cases, ants will go around a treatment, sensing its residue. Is it possible for pyrethroids to serve as a repellent and not be actively killing bugs because they sense it there? I know active ingredients and dilution rates are factors that may play a role, but, in general terms, is the residual kind of like the repelling method that ...

School Is In On Insecticide Classes
Hey! Here are a couple of different questions. This might sound remedial, but are certain pests more susceptible to different chemicals? For example, are carpenter ants (or even ants in general) more susceptible to Suspend SC (deltamethrin) than Talstar (bifenthrin)? Are ants more susceptible to Suspend SC more than roaches are? Suspend Polyzone is a micro-encapsulated product, right? Is S...

Mixing Pesticides
Can I mix Termidor, Demand CS and Migrate when perimeter spraying around the outside of buildings? This is a large food manufacturing property with lots of grass and sometimes geese and other birds. I would like to "kill 2 birds with one stone" and save time over several applications.

Developing The "Green" Routes
I have been trying to come up with a solution for my need to get my foot in the door with green customers. I am strictly a chemical operator for the most part, although I realize green products include chemicals as well. My question is on a combination of a few green products and the application process, and I was wondering what your opinion might be. For carpenter ants in wall voids I could d...

Retail Pros and Cons
Pest Control Technicians are required to follow the "new" pyrethroid labeling. But, what percentage of insecticide is sold to "non" PCO's where the label directions are not actively enforced. My best guess is that more pesticides are applied by non-PMP's and I do not expect "new" labeling to reduce the level of active ingredients various agencies are concerned with, which in turn may bring more...

Pyrethroids - What Can You Do?
Hi Brian. I have abbreviated you question somewhat in the interest of space, but hopefully the intent is the same. I am interested in what you had to say recently about exterior applications of pyrethroids. You mentioned new wording that will be going onto Labels this year allowing broad applications to exterior surfaces of structures when that surface is directly above a porous surface, suc...

More Restrictions?
With the new laws of inside pest control what do you do with a big infestation? I'm talking roaches crawling everywhere, door frames, behind pictures, up high in corners of walls, you name it. Can't see how just treating the kitchen area and bathrooms is going to help.

When Broad Spectrum Goes Bad
When pesticides are applied to lawns and homes don't they knock out pretty much every living insect on the lawn, rather than preserve the non-invasive and 'good' ones? Is the lawn then some sort of field of poison (quite literally) for any beneficial insect? Are the chemicals designed to only kill roaches, etc? Do such chemicals exist? I kind of feel like myself and perhaps a lot of PMPs woul...

IGR Battles
Nyguard vs. Gentrol - I used to use Gentrol for German Roaches before Nyguard became available and I would see lots of twisted wings and deformities. I know that Gentrol "flows" along surfaces and into cracks. Does Nyguard have the same characteristics? I just don't see a lot of deformities like I did with Gentrol.

Is A Little Still Too Much?
I have been a PPO for a few years now. I always wear the proper clothing and PPE, but there are still times when I have come in contact with sprayed product, either from a gust of wind or what not. Should I be concerned about this? Should I be getting periodic check ups? Or, am I perhaps just a little paranoid? Thanks,

Knock, Knock. Who's There? Insecticide.
Insects can either excrete broken down pesticides or use their spiracles to keep them from penetrating as a defense mechanism against harmful substances. Can we assume that, sometimes, well done applications/treatments simply don't work because of this, considering that the right products and equipment were used?

What Makes It Residual?
Please explain to me how some of today's "residual insecticides" actually have a residual effect on bed bugs? I certainly have my doubts that there are residual properties of insecticides outside of DE or insecticide dusts that penetrate the exoskeletons of these bugs.
