What are common pests in Denver?

While pests are all over, the hot spots for different species differ. The following pests are common in the Denver area, and these are some signs of an infestation:

• Rats: You may have a rat problem if you see a rat, hear scratching in your walls or ceiling or find droppings about half an inch long. Rats also create entry points for themselves by gnawing through walls, doors and food packaging.
• Flies: Everyone sees the occasional fly buzzing around their home during the summer months, but if you see more than usual, there’s a good chance you have an infestation. Flies leave feces that look like clusters of black dots and often appear near kitchen sinks, high shelves and around trash. Another sign of an infestation is the presence of maggots, which are fly larvae, in waste.
• Snakes: Snakes are more active during warmer seasons, nesting among overgrown grass, rock piles, wood and debris. Shed snake skins and snake eggs point to infestations. To test if you have a snake infestation, sprinkle flour on the ground where you suspect they're nesting. If you see snake trails in the flour, you know it's time to contact a pest control company.
• Moths: Common moths that invade homes include clothes moths and pantry moths. Clothes moths target wool and cotton, leaving behind tunnels, trenches, silky furrows and small tubes, which are larvae casings. Pantry moths penetrate plastic food bags and create webbing in pantries. Ripe fruit, light and fermented sugars attract moths.
• Mice: Mice that have gotten into your house might dart by quickly or leave rice grain-sized droppings. Mice characteristically give off a distinct musky smell and damage household items by chewing through them. They build nests from found materials and shredded fiber. As mice prefer tight spaces, you may hear scratching sounds inside your walls or ceiling.

How can you prevent pests in your Denver home?

Fighting a pest infestation can be difficult, so preventative measures are the most effective strategy to prevent future problems. Though infestations often require expert intervention, you can take action to keep pests out before they make their way into your home.

Schedule regular preventative pest control

Bugs and small animals can cause serious issues in your home and health if not addressed quickly. Talk to a pest specialist about preventative measures to stop pests from entering your home. Their recommendations may include sealing off access points, placing traps or applying pesticides around the area.

Cover, seal or eliminate food sources

As pests are typically looking for food, making food difficult to access will keep them from invading your home. Food should be a minimum of half a foot off the floor and a small distance away from the walls. Make sure to keep sinks, food storage areas and counters clean and sanitized when not in use, and dispose of food scraps and other trash consistently. Maintain the areas around your trash cans and dumpsters.

Keep up with yard maintenance

Tall grass, leaves, standing water and trash create ideal habitats for insects and small animals. Maintaining a debris-free yard and regularly mowing your lawn and trimming foliage are among the easiest ways to prevent an infestation from taking hold. Should you need expert lawn care assistance, check whether national lawn care companies such as TruGreen cover your location.

Seal off pest entrances

Closing off small entry points will help keep insects and small animals from infiltrating your home. Rats can maneuver through holes as tiny as half-inch in diameter. Inspect your roof and siding for holes, and be sure to seal off damaged window frames. Some pest control companies specialize in keeping pests out.

What are questions to ask your pest control provider?

To find a pest control service with the proper qualifications for your individual needs, ask the following questions during the hiring process.

Are your technicians properly licensed and insured?

Under the Federal Insecticide, Fungicide and Rodenticide Act, the Environmental Protection Agency (EPA) governs the use of pest control chemicals. Moreover, the EPA requires restricted-use pesticide applicators and their supervisors to hold certifications in line with the agency's standards and the laws of the affected states, territories and tribes.

Colorado pest control technicians must pass an exam to get a Commercial, Limited Commercial/Public or Private Applicator License issued by the Colorado Department of Agriculture.

What treatment schedule do you recommend?

The treatment plan a pest professional recommends will vary based on the severity of the infestation, the location of the property, the specific treatment method and the particular pest type. In most cases, pest control companies advise against relying on a one-time treatment to get rid of household pests, as there will likely be insects at different stages of their life cycles that may have laid eggs in hard-to-spot locations.

Pest specialists often suggest recurring treatments, some of which may be only done in the warmer months, while others occur across all seasons. As a proactive measure, they might also recommend preventive treatments every two or three months to stop infestations from getting a foothold.

How long will it take to get rid of pests?

How long it takes for your pest problem to disappear will vary depending on the infestation nature and severity, as well as the insect's life cycle. When the pest control professional applies the first treatment, you may notice a decline in activity, but pests could resurface after hatching, requiring further treatments. On the other hand, you might see increased activity after the initial treatment, as it can force pests out of hiding. Fortunately, this should subside within a few days' time.

Can I remain in my home during pest control treatments?

You can stay in your home for some stages of the pest control treatment, such as when the professional is sealing holes and cracks. But if a pesticide is used, it may need several hours to dry, and you'll have to stay in another location while it dries.

Certain treatments can be especially time-consuming like termite fumigation. The pest control provider erects a tent around your home, which is left in place for three days to apply the pesticide. During this period, you'll need to stay in a hotel or other accommodations.

Are your treatments safe for my family and pets?

An experienced pest control professional can gauge the right amount of a product to use, the time needed for it to dry and when children and pets can safely return to the treated location. Before beginning any treatment, your service provider should inform you about what should be removed from the area, including plants, food and animals.

Do you offer any “green” pest control methods?

Some pest control providers offer green solutions for treating an infestation. This involves using products that don't impact the environment as much as conventional chemical approaches. Eco-friendly pest control methods may include sealing off areas where pests can gain access, capturing rodents or applying pesticides made from natural sources.

What do I do if pests come back?

Many pest control services have guarantees and warranties in place if pests return before a certain date. Companies may offer a one-time treatment or ongoing treatments to resolve a stubborn pest problem. Ask your service provider what options they offer.
