New Mosquito From Asia

In the long line of non-native insect species to invade North America here is another destructive one, the tiger Mosquito. Here in this popular Mechanics article you can learn a little about this new species and its new dangers. It is carrier of multiple pathogens, or mosquito borne illnesses, namely “West Nile virus, St. Louis encephalitis, and Chikungunya—a virus similar to the one that causes Dengue Fever.”
In these last two months of the Summer and through the beginning of Fall it is important to wear insect repellent when you go out into wild lands or parks. Also it is important to keep standing water on your property to a minimum. With many of the new federal laws that have been enacted this year our local Vector Control and your local pest control provider are having a harder time controlling mosquitos in particular, so it falls to each and every one of us to be very careful when we go outside. It is especially important to protect the very young and very old as they are more susceptible to these diseases. Always remember, an ounce of protection can prevent the need for a pound of cure!

Eucalyptus Wars

Here is a rather lengthy but interesting article on Eucalyptus trees and non-native insect species. Eucalyptus, while common to California, is not native and is under insect attack. The questions being raised in this article are many and varied. It provides a good perspective for the issue for and against their being saved.
The bigger question raised is, “Is someone intentionally sabotaging Eucalyptus trees?” This is very interesting to think that insects could be used as bio-terrorists. Think about it, someone could attack the US by just introducing species of insects to attack our food production, scary. This all makes what we do here at PacWest that much more important. Pesticides and Entomological research can help protect us against this type of attack, but this is not fool proof. In any case, the article does debate whether we should even be spending money on this issue and in all respects it is very balanced. We hope you enjoy this as another in a series of non-native insect species blogs.

New Pest Regulations

As of July here in California your Pest Management Professional (PacWest Exterminators included) is required to follow new rules when applying pyrethroid insecticides. First of all this is big news because pyrethroids make up most of the chemicals we use throughout the year. For the past decade they are some of the most popular class of active ingredients here in the US. Why you may ask, well because they meet two of the biggest qualifications for an effective pesticide. One, they are highly effective at killing most insect populations and have a wide range of effectiveness. Two, they are not highly toxic to mammals; this low mammalian toxicity level is prized in the professional community as it keeps our risk of future health issues relatively low.
If they possess little threat to mammals then why are they being restricted? The simple answer is they are very toxic to amphibians and to microbes. These two species make up a large portion of the swamp land and wetlands here in California and across the country. In an effort to be responsible and protect the water these regulations have been enacted to prevent pesticide runoff. These regulations apply equally to Professionals and do-it-yourselfers. If you use any pyrethroid (almost all they sell in Home Depot or Lowes) you must follow these guidelines. There is a helpful site listed here for you to learn about these guidelines and to help you apply responsibly. It is As always, PacWest is doing all we can to follow all of these guidelines for our customers and their homes. If you’re wondering why we’re treating your home differently than last year then now you know why. We are being more responsible for you, your children, and our environment.
