September 9, 2017- What I'm seeing

Insects that I've been getting the most questions on lately are:


1. MOSQUITOES- why are they so HUGE?!
These are floodwater mosquitoes and I'm going to direct you to some great articles that were recently released to provide with all the details.  Click HERE and HERE

2. Hackberry psyllids are back!
Have you been seeing tiny fly-like insects piling up on your windowsill?  If so, you may have hackberry psyllids.  These are pretty common around here in the late summer into fall.  You can see my previous post on them HERE.

3. Floating masses of fire ants- EEK!
If you are in an area that was affected by recent flooding events or you are going to volunteer/ clean up in an area, then please be aware that fire ants can float on flood waters and have possibly moved into new locations.  Take precaution when moving debris!  You can read more on this HERE

Heartworms

I know that heartworms are not an insect (they are a parasitic roundworm), but they are transmitted by mosquitoes so I feel I am within my bailiwick.  So why write about heartworms now?  Today, on my google calendar I have scheduled that my dogs are to get their heartworm preventative.  This task was added to my calendar way back in 2015 and was set to repeat monthly without end.  I also set up my calendar to send me an email reminder on the day, so I don't forget to give my dogs heartworm preventative. I would encourage you to set a reminder for your pets to get their heartworm preventative each month.

large and small dogHeartworms, Dirofilaria immitis, live in the lungs, hearts, and associated blood vessels of various pets (dogs, cats*, and ferrets).  Other animals, such as coyotes, wolves, and foxes, can also get heartworm disease. D. immitis are spread through the bite of a mosquito (Aedes, Culex, Anopholes, Mansonia).

Adult female heartworms living within a dog release offspring, called microfilariae, into the animal's bloodstream.  When a hungry female mosquito comes along and gets blood meal, she ingests the microfilariae and becomes infected.  Under the right environmental conditions, the next 10-14 days can cause the microfilariae to become infective larvae.  At this point, when the infected female mosquito bites another dog (or cat, ferret, etc.) the larvae are transferred to the animal through the bite wound.  When a dog is newly infected, it takes 6-7 months for the infective larvae to mature to adulthood.  Once the adult heartworms mate, the cycle can begin anew.

Heartworms can live within a dog for 5-7 years.  Males reach 4-6 inches long while females can be 10-12 inches long.  The average number of worms in dogs is 15, but can number from 1- 250.  Symptoms depends upon worm burden (how many worms are within the dog).  Dogs with low worm burdens can be asymptomatic, while those with heavy burdens can have exercise intolerance, hypertension, and possible failure of the right side of the heart.

*Both indoor and outdoor cats can get heartworm disease.  Cats are not as susceptible as dogs and heartworms do not thrive within cats.

The best treatment for heartworms is PREVENTION!  Check with your veterinarian about the best preventative method for your dogs and cats.  Remember, we have mosquitoes year round here in Texas, so your heartworm preventative also needs to be all year.
