Pesticide Safety

If the only information I had on pesticide safety came from the newspapers and television, I would be too scared of these chemicals to ever be working with them daily as an exterminator. I certainly can’t blame the general public for their concern about pesticide safety.

However, I get my information on this subject not from the media, but from entomologists and toxicologists; in other words, people who actually know what they are talking about.

I unknowingly learned the basic tenet of toxicology in college freshman year when I found out that it takes more beer to get a 200 pound person drunk than it does to get a 100 pound person drunk. The dose makes the poison. This discovery, by the Greeks over 2000 years ago, remains the basic tenet of toxicology to this day. It is all based on body weight. Everything, in large enough quantities, is poisonous, and nothing, in small enough quantities is poisonous.

The pesticides in use today are diluted until they are only effective against something that weighs as much as a bug. They are biodegradable, so they don’t “build up.”

I have been learning about pesticide safety for over 20 years, because this subject impacts me much more than the general public, as I handle the pesticides in their concentrated form. My customers only have their homes treated with the diluted pesticide. If I ever determined that I was putting myself in danger by my choice of employment, I would get out of pest control and find something else to do.

As far as I can determine, and I have been looking for over 20 years, there are NO scientific studies that have ever found any of the commonly used pesticides harmful! But, you may ask, what about all of the scientific studies that the newspapers and television headline all the time? One of two things:

1. Either they are later determined to be invalid by additional studies (but these stories are never “headlined,” or even reported at all; or

2. They are found to be intentionally designed to reach a pre-determined outcome and therefore, were never actually “scientific” studies at all.

In my studies, I have collected numerous articles by scientists about pesticide safety and of the hoaxes by “environmental” groups designed to scare the public and raise vast amounts of money in the process. Please contact me if you would like copies of some of these articles.

How to Choose a Professional Pest Control Company

Do you need a professional pest control company?

Some pest problems can simply be tolerated or ignored. This will depend on your personal level of tolerance. Some people can accept a few ants or spiders in their homes, others cannot. It becomes a personal choice as to whether a professional pest control company is required. Other pests are economic pests in that they cause financial damage. Economic pests may require a professional pest control company to eliminate the problem.

What is a nuisance pest?

Many household pests (such as ants, earwigs, and boxelder bugs) are classified as nuisance pests; they do nothing except bother you. The fact that they bother you may be reason enough to want to get rid of them. Some pest problems can be self-treated with good results, especially nuisance pests. If the self-treatment doesn’t work to your satisfaction, you can always call a professional exterminator. 

What is an economic pest?

Termites, carpet beetles, bees and wasps are classified as economic pests. They can cost you money through damage and/or doctors bills Economic pests generally should be treated by a professional exterminator. 

Are there pests that should not be treated by a professional exterminator?

Some pests, such as sowbugs, pillbugs and millipedes simply cannot be treated chemically. There is no way to prevent them, so you have no choice but to put with them.  Thankfully, the problem is usually of short duration;

Some pest problems, such as lice, are classified as medical problems and cannot be treated by professional exterminators. Contact a physician in these situations.

Is a contract or a single job required?

The kind of pest that you have will determine if you need a one-time job or a contract for periodic treatment. Many residential pest problems can be treated on a job basis, that is, just one treatment. Spiders,mice, wasps, beetles and some other pests can usually be controlled this way, although you may need a job every year or so. Ants, on the other hand, can only be eliminated with regular service, which is best supplied through a contract. If you anticipate several jobs a year (earwigs in the summer, yellow jackets in the fall, and mice in the winter, for example) a contract may be more economical.

Other reasons people ask for a contract are:

  • peace of mind (we don’t have any problems and we want to keep it that way);

  • preventative (we live in a wooded area and we don’t want to wait until we get a problem); or

  • personal preference (we move a lot, and every time we move into a new house we always hire a pest control company)

What types of contracts are there?

Residential contracts are sold as:

  • Monthly – 12 treatments over a 12 month period, once a month

  • Quarterly – 4 treatments over a 12 month period, at the beginning of every new 3 month period

  • Semi-annual – 2 treatments over a 12 month period, at the beginning of every new 6 month period

  • Tri-annual contracts – 3 treaments over a 12 month period, at the beginning of every new 4 month period

Why would I want a monthly contract?

Pesticides used in homes are biodegradable, usually lasting only 3 months.

If a pest control company treats your house on a monthly basis, and treats the same areas of the house each time, they are putting a layer of active chemical over an existing layer of active chemical. This does not make the pesticide stronger, faster or more effective. It only wastes time, money and chemicals.

Sometimes, a pest control company treating on a monthly schedule will treat a different part of the house with each treatment. Perhaps the kitchen and bathrooms one month, the basement and garage the next month and the outside on the next treatment. Thus, it takes three months to treat most of the house, and some areas never get treated at all.

Your choice comes down to a matter of economics. A monthly treatment (usually about 10 minutes in duration) costs about 1/3 of a quarterly treatment (for example, $50.00 a month vs. $150.00 per quarter.) Pest control servicemen have to produce a certain amount of money per day for the company ($600.00, for example). Therefore, the monthly serviceman has to treat 10 houses per day to make his quota, while a quarterly serviceman has to treat 4.

    Why would I want a quarterly contract?

    A quarterly service schedule decreases the number of appointments per year from 12 to 4, a convenience factor for the customer. It also matches the break-down time of the pesticide. It allows plenty of time for the serviceman to completely treat the house (usually first floor, second floor, basement, garage and the outside.) The thoroughness of this treatment therefore gives superior results AND companies that treat quarterly usually provide free call-back service between quarters!

      Which professonal pest control company is right for me?

      One great way to choose a pest control company is to get a referral from a friend or family member who is satisfied with their pest control company.

      Alternatively, you can call or look at the websites of several other pest control companies and compare what they have to say. Information contained on the Barrington Exterminating Company website will help you evaluate the programs of other pest companies. It is suggested that you find out:

      • Whether the pest control company is a national, regional or local company

      • If it’s a family business or large corporation

      • How long it has been in business

      • Its affiliation with national or state pest control associations, chambers of commerce or local better business bureau

      • Its areas of specialty (for example: termite specialists, residential specialists, bee and wasp experts)

        The Barrington Exterminating Company hopes this information assists you

        in choosing an appropriate pest control company.
