New York City is launching the latest salvo in its never-ending war on rats.     City officials are ramping up efforts to teach regular New Yorkers how to make their streets, businesses and gardens less hospitable to rodents — in other words, to see their neighborhood the way a health inspector would.

Insects are often blamed for many things and more often that you can imagine, strange shaped objects are identified as some “weird bug”.  I could write a book on the strange things that come across my desk that a homeowner is convinced is an insect (I once had a sweet lady send me dried up spagetti, certain her kitchen was infested with worms).  But not every small object is is an insect. Lately, I have had several individuals send me small, oval shaped objects that have been found… Read More →

Bee swarm on a tree, they can also be found on playground equipment, park benches and other structures.

Fleas Fleas are ectoparasites and females require a blood meal to produce eggs. After feeding on a host, females can produce about 30-50 eggs per day. Eggs fall off the animal and into carpeting or other areas of the home or outside in areas where the animal frequents. Larvae feed on organic matter as well as partially digested blood excreted by the adult fleas. After fleas pupate, they usually hatch out of the cocoon in about 2 weeks, but they can remain dormant for up to 5 months… Read More →

Texans, be on the lookout for an invasive beetle to ash trees: The Emerald Ash Borer. The Emerald Ash Borer has recently been found just outside our doorsteps in Colorado in late 2013.  In fact, the Emerald Ash Borer may very well already be in Texas, as most experts believe there may be as many as three years time between introduction and detection! Emerald Ash Borers lay their eggs in the crevices of the bark of the Ash and the larvae hatch and burrow into the outer sapwood of the Ash… Read More →
