Jul 13, 2012 – The MOA of Foggers

QUESTION:

Do spiders breathe in foggers? How do foggers work?

ANSWER:

We can answer this on two levels, the method of “breathing” by spiders and other arthropods and the way that foggers and mists actually affect the arthropod pest. The first is on breathing by bugs, and spiders have a somewhat different setup than insects do. Insects usually have “spiracles” that are small openings along their sides or somewhere else on their exoskeleton (on maggots they are on the end of the abdomen). These allow air to move into the body of the insect so that the air then is transported passively through smaller and smaller tubes to each area of the body, supplying the needed oxygen throughout. Some aquatic insects will have gills that remove the oxygen from the water, as with dragonfly larvae. 

Spiders and scorpions have “book lungs” under their abdomen, and these are large folds that lie within a pocket, more or less like thick pages in a book. This maximizes the surface area that is in contact with air (oxygen) and surrounding the book lungs will be large quantities of the spider’s blood, allowing the oxygen to move into the blood for transport throughout its body. So, neither spiders nor insects nor any other arthropod “breathes” actively in the manner of vertebrates. We actually pump the air in and the waste products out, and anything in that air (dust, vapors, droplets) gets pulled into our lungs as well. Particles and droplets are far less likely to move through the spiracles or into the book lungs of spiders, so getting the tiny droplets of a fog or a mist into a spider is not likely to happen. This is what foggers emit – droplets – and they may be very small in diameter but they are droplets nonetheless. 
However, some insecticide active ingredients will vaporize to leave the vapors in the air, and this may be part of the mechanism of pyrethrum. Even though the droplets have evaporated the vapors remain to some extent, and thus we get some repellency to flies from the use of aerosol misting devices set up over doorways. For most other active ingredients we should not expect that vaporization, and the droplets from foggers go up into the air and finally settle down onto horizontal surfaces below, with the active ingredient still in that droplet and thus settling only on that surface once the water or other diluents evaporate. The tiny droplets from foggers go only where air movement carries them while they are still aloft, and for the smallest of droplets this could take an hour or so. But, they are incapable of entering sealed areas such as wall voids, drawers, sealed packages of food, closed closets, etc. This is why fogging the air is not going to control an infestation of food pest insects where the larvae are living and feeding inside closed packages of food.

Jul 10, 2012 – Scorpions – Who’s To Blame?

QUESTION:

Friends of ours own a rental property in an area with scorpions. The renter’s neighbors filed a formal complaint with the homeowners’ association that scorpions are “nesting” in the yard and are responsible for the complainants’ problems. First, do scorpions nest? Second, as pest control operators are we legally responsible for any issues that arise from scorpion problems such as medical bills, etc?

ANSWER:

Well…………..a couple of interesting issues here and I am likely to tread very carefully on any advice about legal matters. But, in my opinion if someone (in this case the complaining neighbors) feel so strongly about this and feel their complaints are not resolved they may resort to a lawsuit, and in a lawsuit the attorneys are going to involve as many people as possible in an effort to get as much of an award as possible for their clients. If you are charged with eliminating pest presence on a property then yes, it is very possible that someone is going to claim that you have failed to do what you were contracted to do because those pests continue to be present on that property. And, therefore, valid or not you may become involved and told that you should feel obligated to pay for any losses suffered by people, and then of course those dandy “punitive” damages of pain, suffering, loss of sleep, etc. 

So, here is the question? Are there any scorpions living on the property of your customer? It is very easy for disgruntled neighbors to start pointing fingers at other people when they have problems, and rental properties may be subject to this even more where neighbors may not be pleased by having renters near them. Feel happy that this so far has gone only as high as the HOA, and you need to work with them to resolve it, including educating the HOA folks on scorpions, their danger or lack of danger in your area, and the ways that they can be prevented or eliminated. I believe that you should perform a very thorough inspection of your customer’s property to determine if, indeed, there are any significant numbers of scorpions living there, and personally I believe you also should be given the right to inspect the properties of the complainants to see if they themselves are harboring these terrifying bugs. (That was a bit of sarcasm). 
Who knows but that this may become an opportunity for you to pick up some additional customers if you handle it diplomatically and professionally. Obviously you have people living there who have zero tolerance for scorpions, and perhaps many other bugs, and by educating the folks who live in that area on the arthropods present there and the choices for managing them you may be able to defuse this crisis. (Again, sarcasm). The important thing is to show quickly that you take this seriously, but that you want to handle it properly by ensuring that these beneficial (not sarcasm) arthropods are actually living in and near these homes and that you have found where they are harboring. Scorpions may not “nest” in the sense of social gatherings, but attractive hiding places could have multiple scorpions in them. Be aware that one inspection tool is UV light. At night you can use an ultraviolet flashlight (Univar sells these) to search for the scorpions, which fluoresce when exposed to that light. 
Bottom line as I see it is that you cannot escape some level of involvement if upset people wish to sue for damages. This is just a reality of what our industry does. And, upset people are more likely to believe that they are actually being harmed and will seek medical attention for anything they believe is related to the concern. So, jump in now with your legitimate desire to resolve this amicably for everyone, but showing that the property you are working with is or is not the epicenter of the Great Scorpion Invasion of 2012 is important.
