- Rodents are implicated in 55 human diseases. In Texas, murine typhus is on the increase with nearly 3/4 of all U.S. cases in the southern part of our state.
- Over 100 pathogens have been associated with house flies, including Campylobacter and the deadly E. coli O157:H7, and possiby community-acquired MRSA.
- Although it's been hard to connect cockroaches with outbreaks of human disease, the German cockroach has been shown to be a carrier of at least 60 species of bacteria, fungi, molds, helminths, protozoans and viruses.
- Cockroaches have also been implicated in causing asthma, especially in pre-school aged children. In older people, definitive evidence shows that cockroach allergens exacerbate asthma.
- Mosquitoes may be the worst, with their frequent association with virus transmission, heartworm (in dogs) and other disease.
I've discussed WNV before in this blog, partly because we have had a number of cases in my Dallas community, but also because WNV is typical of many mosquito borne diseases which pop up periodically in the U.S. I am convinced that our industry can and should be doing more for the public with regard to mosquito control. Although most mosquito control is (appropriately) conducted by county and city health departments or mosquito control districts, PMPs can play an important role in the fight against mosquito-borne disease. Here some of my thoughts on how you can help.
- Train your technicians to be on the lookout for mosquito breeding sites when conducting inspections of residential accounts. No one thinks their backyard is the one breeding mosquitoes. It's always the next-door neighbor or the creek down the street. In one study done by the Dallas County health department a few years ago, 25% of the folks who called the health department to complain about mosquitoes had mosquitoes breeding in their own backyard. I know from experience that it's easy to forget to turn over the wheelbarrow or put away the kids' toys before rain or irrigation water can sit and breed mosquitoes. Having an extra set of trained eyes looking over the yard every month can make a significant difference.
- Educate your customers about mosquito control. How to recognize and report problems, explaining the importance of repellents, and reports on the local mosquito situation in your community(maybe through a newsletter, your website, or monthly bill inserts) can be a much-appreciated service and increase your value to your customer. A lot of people forget about mosquitoes after the spring tides of floodwater mosquitoes ebb, but now as the summer heats up the risk of mosquito-borne disease actually increases.
- Consider including mosquito control among your summertime pest control services. In addition to backyard fogging prior to outdoor events, residual sprays applied to mosquito resting sites (via sprayer or backpack ULV blower) can be very effective. Of course larvaciding in some locations can be helpful also.
- Refer your customers to the Mosquito Safari website for more information about mosquito control and how to find mosquito breeding sites in their own backyards.
