• Common Arizona Pests

  • Spiders

    The Arizona brown recluse spider (shown), and the black widow are the most common "harmful" spiders commonly found in Arizona.  Most spiders are harmless to humans.  In fact, spiders are considered beneficial because they feed on insects. Outdoors, spiders serve an ecological purpose.  When they're found indoors, however, spiders build unsightly webs, often with leftover dead insects in them, which far outweighs any benefits they may offer in keeping the number of pests down.   

  • Fleas

    Fleas are pests to both humans and their pets.  Fleas can infest homes and businesses even if there aren't any pets present, however. Coyotes, feral cats, bats, squirrels, and rats can also bring fleas to your doorstep. Fleas are found throughout Arizona, but not on a large scale here in the Valley of the Sun.  Fleas go through a complete metamorphosis after hatching from eggs.  They need a high level of humidity which we generally don't have until the monsoon season. 

  • Ticks

    Ticks can be a real problem in Arizona.  You may have never had a tick problem on your dog or other pets, but if you take a trip up to the mountains to get away from the heat or visit a dog park, then you will be dealing with a tick problem in your home.Certain ticks carry diseases such as Rocky Mountain Spotted Fever and Lyme Disease.  Ticks should be dealt with quickly if they're found in your home to avoid any chance of catching these serious diseases. 

  • Cockroaches

    There are many varieties of cockroaches that we have to deal with in Arizona.  The American cockroach is primarily an outdoor roach that occasionally finds its way inside by crawling or flying.  The Oriental Cockroach can be found both inside and outside.  All they need is a dark moist area such as under your sinks in the kitchen or bathrooms, or outside near an irrigation box, or near a drip line.  The German Cockroach lives only inside homes and is often found in the kitchen or the bathroom. 

    Cockroaches thrive in areas that have a food or water source such as your cupboards, the dishwasher, microwave or oven, or basically anywhere there are crumbs, grease or anything edible. Cockroaches can cause damage as they spread filth from unsanitary areas such as sewers, garbage disposals, the trash, etc. 

    Cockroaches can spread filth to food supplies, prep areas, dishes, and utensils and they can also carry diseases.  Cockroaches can also breed at an alarming rate.

  • Silverfish

    Silverfish can be found anywhere in your home.  They can eat almost anything that contains protein or carbohydrates such as sugar, beef extract, and dead insects, but they're not limited to those foods.  They can also each starch, paper, some synthetic fibers, glue and paste.  

  • Earwigs

    Earwigs, sow bugs, and pill bugs (roly-poly bugs) are found around decaying vegetation, but they can also find their way into your home. The species most commonly found in Arizona is the European Earwig.  European earwigs are easy to spot by the large pincers on the end of their bodies.

    arwigs serve some ecological benefits ad they eat scales and aphids, but they can also feed upon your garden plants as well.  In addition to the damage they can cause to your flowers, fruits, and vegetables, earwigs can enter homes and other buildings during the summer months.  While they aren't as harmful as other insects can be, earwigs do give off a disagreeable odor.
