A new beginning:

Here we are with a new mosquito trapping season fast approaching. We are planning on starting our surveillance monitoring a week from today. But we have been working continually since the “end” of last season actively identifying potential problem areas and working to minimize potential mosquito impacts.

A quick note about last year: testing done via the Department of State Health Services (DSHS) identified 5 positive mosquitoes out of all the traps that we placed last year. We were also notified about 4 human cases of the fever form. The City of Plano placed more than double the amount of traps than any other municipality in Collin County and we will continue to expand our trapping as necessary to make sure we are identifying all potential areas.

Just last week, we deployed 2000 mosquitofish (Gambusia affinis) into a few areas of the city (http://www.nbcdfw.com/news/local/Plano-Testing-Mosquito-Fish-in-Golf-Course-Ponds-253458431.html). This is just part of our Integrated Mosquito Management plan and is the 4thtime we have done this is the past 2 years. We are planning on doing this again in September based on areas that we identify that could use the fish help as a biological control mechanism.

Now is the perfect time to get a head start on minimizing potential mosquito habitats in and around your home. Check flower pots, gutters, toys, or anything else that could hold water for more than 10 days. With everyone’s help, we can continue to keep down not only mosquito numbers, but WNV as well!

As fall draws near:

Posted on September 20, 2013 at 12:00 AM by Ryan Janowski

This week, the week of September 16th through September 20th, 10 traps were placed at various locations throughout the city. Approximately 120 mosquitoes were shipped to DSHS for arbovirus testing. We are starting to note lower trap counts as the night time temperatures start to drop.

We were again notified by the DSHS that a trap that was placed in the 75074 zip code came back positive for WNV. This marks the 5th positive mosquito sample this season. We sprayed the area where the mosquito was isolated as well as the Balloon Festival areas in accordance with our Integrated Mosquito Management Plan this previous Tuesday. We were also notified by Collin County that a 4th human case, within the 75025 zip code, has come back positive in Plano. All human cases to date have been the less dangerous fever form of the virus. Please check the website for further information like the spray map as well as the FAQ’s that are posted and if you have any  further questions, don’t hesitate to call the Environmental Health Department. We do again want to remind everyone that if your area is due to be sprayed, you can opt out of the spraying by calling the Health Dept. We are continuing our habitat and larval assessments throughout the City of Plano.

With the numbers that we are currently trapping and the time of year that we are actually isolating WNV is more in line with what we would still consider a normal WNV “season”.  At this point, we are planning on doing continual surveillance, larviciding and habitat assessment into October. Once nighttime temperatures are consistently in the 60’s, the mosquito populations start to slow down. Once temperatures start to reach into the 50’s consistently, mosquitos will go into a sleep mode and begin their over-wintering process.  

Please keep an eye out around your house to minimize mosquito habitat and breeding. With everyone’s help, we can continue to keep down not only mosquito numbers, but WNV as well!

September has arrived:

Posted on September 4, 2013 at 12:00 AM by Ryan Janowski

This week, the week of September 2nd through September 6th, 5 traps were placed at various locations throughout the city. Approximately 150 mosquitoes were shipped to DSHS for arbovirus testing.

We were again notified by the DSHS that a trap that was placed in the 75074 zip code came back positive for WNV. This marks the 4th positive mosquito sample this season. We are planning to spray the area where the mosquito was isolated this Thursday, the 5th starting at approximately 10 pm in accordance with our Integrated Mosquito Management Plan. Please check the website for further information like the spray map as well as the FAQ’s that are posted. If you have any questions, don’t hesitate to call the Environmental Health Department. We do again want to remind everyone that if your area is due to be sprayed, you can opt out of the spraying by calling the Health Dept. We are continuing our habitat and larval assessments throughout the City of Plano.

With the numbers that we are currently trapping and the time of year that we are actually isolating WNV is more in line with what we would consider a normal WNV “season”. Typically, positives are isolated around August and September and the season tends to wind down sometime in October. At this point, we are planning on doing continual surveillance, larviciding and habitat assessment into October. Once nighttime temperatures are consistently in the 60’s, the mosquito populations start to slow down and die down.

Please keep an eye out around your house to minimize mosquito habitat and breeding. With everyone’s help, we can keep down not only mosquito numbers, but WNV as well!
