Rain, mosquitoes and fire ants
By John Ford

Following the rains of the past two weeks, it will be several days before low-lying areas in Kleberg County become dry.

There will be standing water for an extended period in some locations. It is safe to say that two pests will take advantage of the soggy conditions, mosquitoes and fire ants.

Mosquito populations will explode and make it unbearable for humans and animals, especially during the evening hours.

Foggers and other types of products are available and do provide some relief from the pest.

However, there are some simple steps that can be taken that reduce populations around the home.

 Eliminate containers such as tires, buckets, cans and bottles that collect and hold water.

 Discard old pieces of plastic that collect water, empty plastic wading pools and store indoors.

 Empty and scrub bird baths, clean pet and livestock watering pans and troughs frequently.

 Fill holes or depressions in trees with sand and make sure that there are no leaky outdoor faucets.

 Keep weedy and grassy areas mowed.

Of course when discussing mosquito populations one must mention West Nile Virus.

Horses, donkeys and mules seem to be most susceptible to West Nile.

Horses should be on a regular vaccination schedule. Horsemen with questions about West Nile vaccination or the virus should consult with their veterinarian.

If possible, house animals at night in stalls that offer protection from mosquitoes.

Fire ant activity is also on the increase.

After this wet weather, problem mounds are appearing, even in those lawns that the Texas two-step method of fire ant control has been practiced.

The rains have also moved mounds and it is not unusual to see colonies floating in ditches and runoff water.

Problem mounds can be treated with granular products containing an insecticide that releases into the soil, usually when drenched with water.

Sprinkle the recommended amount of product around and on top of the mound. When directed on the label, sprinkle 1 to 2 gallons of water over the granules with a watering can.

Sprinkle gently to avoid disturbing the colony and washing the granules off the mound. The other option is to use a liquid drench that is applied directly to the mound.

As with granules, 1 to 2 gallons of water is needed per nest. When applying insecticides, read and follow the label directions.
