Ants come in many varieties from sugar ants to black ants to red ants to pharaoh ants to carpenter ants to fire ants. If you have ants at your house, you likely will know they are there no matter which variety they are.

In general, ants are subterranean – in other words, they live underground. They come above ground during the day to search for food and return underground at night.

One problem with ants is people often don’t know the difference between an ant and a termite. Luckily they are easy to tell apart in their adult stage. The ant has three distinct body parts whereas the termite has only two distinct body parts.

Unfortunately when an ant colony gets too large the send out a group of winged ants to start a new colony. These flying ants are not highly coordinated and tend to land on anything they hit. In our years of pest control in Colorado, we find over and over that the winged ants land on the chimney of the tallest house in a neighborhood and swarm down the chimney and pour out the fireplace into the living space. We have received many phone calls from panicked homeowners with flying ants in their living room.

To fix this problem, simply light a small fire in the fireplace. This will eliminate the ants in the chimney. You can then treat the living area with any over the counter pesticide labeled for ants. If you are still concerned you can cover the outside of the chimney with black plastic and duct tape. Just don’t forget to remove the plastic before winter sets in.

Bed Bugs

Bedbugs (or bed bugs), are becoming more common not only locally in the Denver area, but in the entire United States, and even worldwide. Do you travel? Are you concerned about picking up bedbugs on your trip and bringing them home? Unfortunately this happens all too often, but there are things you can do to reduce your risk,
such as:

  • Check into your hotel, get the key to your room and go check the mattresses before you carry your luggage up to the room. – to check the mattresses, pull back the bedding, including sheets and any mattress covers, and look closely at the seams around the mattress. If you do not see any bugs or anything that looks like an insect egg, you are good to bring your luggage into the room.
  • If you get home and are still concerned you may have picked up bedbugs on your trip, do not bring your luggage into your house. Instead, you can remove the clothing from the luggage into a bag and take it to a laundry, (keep in mind you still need to leave the luggage in a very warm place (eg: out in the sun) for several days to kill the bedbugs in the luggage. Or you can contact our office to get a technician out to provide a service that would eliminate any bedbugs from your luggage before you take it (and the bugs) into your home.

Clover Mites

CLOVER MITES are a very small insect – the size of the head of a pin or the dot of an “i”. The problem with them is, if you have one, you have thousands. They tend to move in one big mass. You can tell if you have an invasion of clover mites, because they are a small red dot and if you squish them they leave a red streak.

You usually see these small mites in spring and sometimes fall. They do not bite or infest plants, but they do leave a stain when squashed. They eat clover, grasses and other types of plants around a yard. They live in lawns, however they do not like water, so when the sprinkler water hits them, they move away from it, usually toward the house. These mites molt and lay eggs in the rocks and bark around a house or building. Most often you will see clover mites on the windows or sliding glass doors, on the warmest side of the house and occasionally they will get into the house, covering a portion of a wall or curtain.


In Colorado the most common cockroach is the German Roach. The German Roach is 1/2 to 5/8 inches long when mature. They are light brown to tan with fully developed wings. Roaches are found mostly in kitchens and bathrooms where there is food, water and places to hide. Cockroaches feed on all types of human food as well as pet food, toothpaste, soap, glue, etc. They are most active at night when they forage for food and water. If you see roaches during the day, this indicates a huge population. The German Cockroach can grow from the egg stage to the adult stage in a little as 36 days. The adult roach lives 100 to 200 days.


Crickets are loved by some people for their music, and hated by others for their noise. If you have crickets outside your home, they usually aren’t too much of a bother, but it doesn’t take them long to find their way inside and once they do, few people can tolerate their noise. These insects are nocturnal, so most of their chirping starts in the evening and can go on all night long.

The common house cricket, known also as the field cricket, is generally black or brown in color. They are 1 to 3 inches long with their antennae. Crickets are scavengers and generally feed on decaying plants. They will bite humans, and while their bite is painful, they generally will not break the skin. You can often find crickets for sale in pet supply stores, since they are used as food for other pets such as snakes, frogs, lizards and such.


ere are many varieties of flies, but the three that seem to cause people the most problems are the

  • House Fly – 1/8 to 1/4 inches long, Black to dark brown. Life cycle is approximately 7 days. They lay their eggs in organic material and feed on a range of food from excrement to solid food. These flies usually prefer soft to liquid food.
  • Blow or Bottle Fly – 1/8 to 1/4 inches long, Metallic blue, green or yellow. Life cycle is 15 to 20 days. They lay their eggs on meat or fish, but also on organic material. They feed on organic material, mostly meet.
  • Fruit Fly – 1/8 inch long, Yellow-brown to dark brown. Life cycle is 8 to 10 days. They lay their eggs on the surface of fermenting fruit or vegetables or areas where moisture and yeast are abundant. These flies feed on fermenting fruit or vegetables and are common around browning bananas.

What the customer can do: Some fly control can be done by the customer, such as removal or clean up of trash cans, compost areas, diaper containers and exposed fruit. Complete and thorough sanitation is necessary to eliminate fly infestation.

What we, the pest control company, can do: We will try to locate the harborage area, such as trash receptacles, compost, or decaying yard material. We will spot treat such areas and possibly locate fly sticks in inconspicuous areas. We may recommend a vector system for commercial locations depending on the extent of the problem.

Miller Moths

Miller Moths are the most common moth in Colorado.

The miller moth comes from the army cutworm. The larvae of these cutworms are in the crop fields of eastern Colorado and western Kansas. When conditions are just right, the larvae hatch and millions of miller moths begin a flight to the mountains of Colorado.

Unfortunately along the way, they stop at our houses, and often become an overwhelming nuisance. Miller moths do not bite or eat fabric, but they do get a dusty substance all over anything they touch. They are attracted to lights and will swarm around them. Many people leave their porch lights turned off in order to keep some of the millers outside. If your house is log or has any wood siding, wood decks or is surrounded by pine trees, you will likely have a higher infestation than houses without these features. While it’s true the miller moths will only last a short period of time before they resume their flight west, they can be overwhelmingly annoying while they are around.


Mosquitoes are one of the biggest nuisance pests in the world. Colorado has always had problems with mosquitoes both on the plains and in the mountainous regions. Pest control companies must have certain licensing by the Department of Agriculture to treat for mosquitoes, but there are products you can use and steps you can take to reduce the infestation on your property.
