Come on rain!

Well, here we are again with another week of lower mosquito populations than is typical for this time of year. We are continuing to trap throughout the City of Plano and are even deploying some of our CDC light traps to take a look at the mosquito populations that don’t typically carry West Nile virus as well. The light traps are designed to use a small light bulb and a CO2 source, dry in this case, to attract mosquitos. We are seeing very favorable numbers in these traps as well. There is some West Nile virus activity going on in 3 counties in Texas however. Always be using the 4 D’s (Dress, Dawn/Dusk, Defend, Drain) while outdoors to minimize the risk for West Nile virus.

Have a safe and happy 4th of July!

Its quiet, too quiet…:

So far we have been trapping for about 3 months now in locations throughout the City of Plano. We have seen very low numbers of mosquitos in our traps which is very encouraging. The general line of thinking here is that with the number of hard freezes that we had this winter, coupled with a moderate spring and seemingly later start to the hot weather, this summer has pushed the mosquito season back by a little bit. The numbers we are catching now are what we typically see early in May. But this doesn’t mean that we can keep our guard down! Always be using the 4 D’s (Dress, Dawn/Dusk, Defend, Drain) while outdoors to minimize the risk for West Nile virus.

A few quick notes: We are starting to place some of our CDC light traps out to get a general idea of what comprises the total mosquito population area as far as different species are concerned. The trap that we use to collect the mosquito that could potentially carry WNV is known as a gravid trap, designed to catch egg laying females. The light traps are designed to catch a more wide variety of mosquitos because it doesn’t rely on female mosquitos coming in to lay eggs. It uses CO2 and a light source to attract mosquitos into the net.

Trapping has begun:

Your Environmental Health Department has begun trapping throughout Plano with our gravid surveillance traps. Thus far we have only caught a handful of mosquitos. This hopefully will bode well for the rest of the season. The low numbers that we are seeing are probably due to the number of hard freeze days that we experienced this past winter. The primary species of mosquito that carries West Nile Virus in the DFW area “hibernates” when the temperatures get about 50*F. They look for places that they think they can survive the winter. With the number of hard freezes that we have had, and with the late freeze especially, the mosquito numbers could very well be knocked down a bit. Now, this doesn’t mean by any stretch that there won’t be mosquitos or that more won’t come back. But, with your help in minimizing potential habitat, we can have a great effect on the mosquito populations.

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!
