Fleas

Roughly 80 species of fleas can be found living in Colorado, which is among the largest number found in any state; however, flea infestations around the home and on pets are not nearly as common as in other areas of the United   States.  Colorado’s typically dry climate is not favorable for the immature stages […]

Duff Millipedes – No, they are not tiny caterpillars or larvae

We receive countless calls every year about tiny caterpillar or worm like insects crawling along walls and window sills inside of homes.  Due to their minuscule size of only about 1 mm as an adult, duff millipedes can be difficult to identify.  Often mistaken for the much larger larval stage of dermestid beetles (carpet beetles), […]

Solpugids – a.k.a Sunspiders or Windscorpions

Relatives of arachnids like true spiders and scorpions, solpugids (or sunspiders as they are more commonly called) have 4 pairs of legs, large jaws and long, leg-like pedipalps (mouth parts used for manipulating food and climbing smooth surfaces).  Their oversized jaws and quick movements tend to frighten those that encounter them.  Sunspiders powerful jaws are […]
