Mosquito trouble is the worst for decades

Dr Alan Wheeler and Chief Officer Nellie Pouchie on Radio Cayman

(CNS): Mosquito and Research Control Unit Director Dr Alan Wheeler has blamed the worst mosquito problems for two decades on a number of natural factors, such as COVID-19 and Tropical Storm Grace, but not the management issues that have surrounded the MRCU over the last two years. Wheeler, who was appointed as director in July this year, said that they were working hard to tackle the surge in the black salt march species causing the current trouble.

However, the MRCU had been dealing with a number of problems under the leadership of Dr Jim McNelly, who led the unit from March 2018 to March 2021. He left under a cloud, after his staff sent a letter to the ministry claiming that, rather than the tried and tested methods of mosquito control that Cayman had deployed to significant success, he had switched to methods that had contributed to the widespread rise in black salt marsh mosquitoes and the disease-carrying Aedes aegypti.

When Dr Wheeler appeared on Radio Cayman’s For the Record last week, he apologised for the outbreak of the swamp species and described the activities currently underway. He said the surge in the marsh mosquito was largely a result of the reduced control efforts last year during the pandemic, high tides both last year and this, followed by back to back storms over the last month that created flooding in the wetlands.

One man-made problem impacting the control of swamp and marsh mosquitoes that Dr Wheeler did identify was development, which is cutting into the wetlands and breaking up the mangrove areas into smaller and smaller pieces. This makes the aerial operations to deploy the larvicide used to keep all of the native mosquito numbers that breed in the wetlands under control much more difficult.

He explained that spraying the disconnected reduced areas is much more difficult than spraying across a larger area, and as a result the MRCU was examining the possibility of using drones to control the reduced areas of mangrove on the western side of the island.

The MRCU is currently focused heavily on responsive control because of the current surge and has turned its attention away from researching new methods, but Dr Wheeler said they expect the black salt marsh to be under control by the end of this week.

He accepted that the situation had become worse over the last two years but said he believed that by next year things would be back under control. This year the unit has been concentrating on killing adult mosquitoes, but the most important work was the larvicide, which targets the eggs.

Dr Wheeler said his staff has been working flat out for the last six weeks. However, he said nothing about recent allegations that the unit continues to be plagued by staffing problems and a shortage of pilots and technicians to keep the two small planes in the air.

CNS has persistently asked for information about staff shortages, the number of pilots and succession planning at the MRCU but none of our questions have been answered.

    Fogging trucks out in Prospect last night. This morning I found a LOT of dead mosquitoes floating in the pool. And Thankfully no bees .. and didn’t get bitten on my walk! Finally able to go out without being bitten and worse, having mosquitoes follow me into the house and pester me for hours!

    I love hearing people say that the mosquitos that are biting are the “oxitec” mosquitos. There are 35 different species on this island.

    With no disrespect. One more year too get things up in running. Our people will have too stay in on lock down. Because of the angry pickersome mosquitoes and smoke from the fires in our communities people trying too help keep the mosquitoes away.

    Perhaps this is a result of their previous work? Don’t get all religious on me frothing at the mouth.

      Ok. Here is a more realistic suggestion. There was a tropical storm. It rained a lot. There was a ton of standing water. Mosquitoes lay eggs in standing water. Nobody has been spraying
      A week or two later you get swarms. Its not complicated. It has nothing to do with what happened years ago.

      Spot on comment! He has always been a major part of the problem in that department as he stirs up problems and creates conflict within. He has undermined the directors position for the past 10-15 years consistently and now that he finally holds the position he has bullied himself into he is making nonsense excuses…

      I concur.

      Grace should not even been mentioned in this. There is a systemic management collapse at the MRCU, mainly due to the reasons you mentioned. Wheeler is part to blame for creating chaos.

      There is no foresight and no planning.

      XXXX I understand, for example, the main pilot reached retirement age and was not granted renewal of contract. If true, a leader would rehire on a contract basis for continuity while a training programme is in place to eventually replace him. The retirement age didn’t just appear. It was known to be coming up. So this may have very well resulted in a stall of spraying by plane and therefore in part has contributed to the surge in mosquito population.

    Dr. Wheeler is spouting total BS!! Even though apparently Dr. McNelly was no prize, it appears this increase in mosquitos all over the island has happened on Dr. Wheeler’s watch!

    I’ve lived in my home for 29 years and enjoyed every evening outdoors without ANY mosquitos until the last 2 months! I’ve witnessed many rainy seasons and hurricanes (incl. Ivan) and never experienced mosquitos like this in my area!

    I posted a comment to CNS when Dr. Petrie left MRCU and surely my comment has come to pass!!

    Dr. Wheeler, please get these mosquitos under control quick, WITHOUT subjecting us to ANY MORE dangerous chemicals or… give up the post!!!

    Typical mismanagement for a little third world island. Get used to it. It is only going to get worse as the money runs out. There is no functional Mosquito and Research Control Unit on island and there will not be until the UK steps up.

      Since you always want the U.K. to “step in” maybe you should just “step out”.

        Maybe we should rather have the USA step in then? Or maybe the Taliban for that matter?

      • Anon says:

        I think, the point is, not that the UK presents some sort of nirvana, more that they are too hands off when they should be ‘hands on’ forcing the politicians to serve the people and not themselves. Staffing will always be an issue here for specialist roles BUT there is NEVER any urgency to get critical roles filled. Maybe the politicians should be paid on performance. It might make the civil service act. Quicker.

        I think the island would be better off if you and your “kind” step out. I didn’t say they were the best, but they are your keepers. Wait a year and see what they will have to do to save Cayman islands from the human virus that is destroying it now.

    I’m sorry to say but the concept of controlling mosquitos through spraying chemicals and larvicides all over us is outdated, unsafe and has to change. Genetically modified mosquitos is the future. Miami knew this when they head hunted Bill Petrie away from Cayman. This is the exact correct use of GMOs. Give me a sterile male mosquito over carcinogenic and teratogenic chemical sprays any day.

    Someone needs to do an FOI request for the stats on mosquitoes caught in the MRCU’s traps over say the past 5 years, and the changes in techniques / chemicals made in the same period.

    I heard they counted 19k mosquitoes from a single trap in West Bay in a 24 hour period a couple of weeks ago. COVID my ass!

    I smell total BS excuses. MRCU workers were considered essential workers, no need to blame the pandemic (very convenient though). A more plausible excuse was runway resurfacing, but he failed to mention that and preferred to blame others. High tides occur every year so that isn’t valid either. Seems like the new director wants to blame everyone but himself!

  22. Anonymous says:

    The horrible mosquito outbreak of the last three years coincided with the appointment of the previous Director. That cannot be a coincidence.

    But what is so puzzling is that MRCU is a critical Govt agency. Why did the previous PPM Govt allow it to go off the rails? Will the new PACT Govt take urgent steps to resolve the situation?

    You would think that every Govt since 1966 would have put MRCU to the top of the list for funding and resources. Grand Cayman is totally reliant on this agency for the health and comfort of local life and the viability of the tourism industry.

      This is the problem in many government entities- they ignore problems until there is a crisis. I was walking on South Sound last week after 7 pm and it was like walking into a nest. My ears were bitten, my legs, etc. I have lived here for more than 25 years and I have never encountered any thing like this. It is alarming how Government ignores our urgent concerns.

  23. Anonymous says:

    The fact that CNS has been unable to get answers to basic questions is, in my opinion, a clear indication that the MRCU management is being less than fully honest about our mosquito control problems. This does not reflect positively on the current MRCU leadership and management and it would reasonably cause one to conclude the the MRCU continues to lack the leadership needed to get our mosquito problems under control.

      It’s always been that way, I recall asking Mr. Petrie about chemicals used in their control of mosquitoes both historically and present. He clearly avoided naming any and said whatever they used and were using were safe.
      Being opaque about these things only breeds mistrust. I wonder if anyone at DOE, DEH, Water Authority, or MRCU is actually doing any soil/surface water testing to see how long chemicals they use stick around?
      I understand there are risks and benefits to using insecticides but to be cloak and dagger about it does not help the public weight those risks.

    What does covid have to do with this. The planes could fly, same way the RCIPS operations carried on. And actually saying they have been flat out for six weeks?? With one plane grounded because they finished a pilot (who is Caymanian, so not sure what the contract issue is) – all smacks of mismanagement under the current watch.

  25. Rodney Bar says:

    I do believe that the good doctor needs to understand that he works for us. The taxpayers and voters of the Cayman Islands.

    When re[resemtatives of the people, such as the press ask questions, they should receive answers. And the answers should be provided promptly and completely, with supporting data. Not just excuses and vague run-around responses.

      Well. The storm left a lot of standing water. Where do you think mosquitoes come from?

        Where do you think larvicide comes from? It takes a few days for a mosquito to emerge from standing water.

          How many days if the water is sitting not standing?

          I think that it’s very easy for all you armchair quarterbacks to sit here and complain. I think anyone with a brain would realise that it would be impossible to get larvicide into pools of water covering the island that quickly. Even if the MRCU was being run competently. And we all know it isn’t. But to suggest that the storm isn’t a cause of this is pretty dumb.

        Every storm, even just a tropical wave, produces plenty of standing water.
