Mosquitoes are not particularly mobile and often stay within a few hundred feet of where they originally hatched. After the application, adult mosquitoes carry the chemicals back to their breeding grounds until breeding sites are completely eliminated.  

Your lawn needs 1 to 1-1/2 (3-4cm)" of water weekly. Mother Nature provides water, but she sometimes needs help. To determine the need for supplemental water, look for these telltale signs of oncoming drought stress:

  • Areas of the lawn especially near concrete or asphalt (sidewalks and driveways), under large trees and on slopes, take on a dark, silvery or smoky blue-green haze. In extreme cases the lawn appears yellowish.
  • Footprints or lawnmower wheel marks don't spring back shortly after they are made.
If your lawn shows symptoms of drought, water it immediately regardless of the time of day. Under normal circumstances, early morning is the best time to water your lawn so that the leaves can dry slowly and naturally without too much evaporation, and instead with most of the water penetrating the soil. Regular, fairly deep watering is better than daily light sprinklings. Deep watering and allowing the lawn to dry out between watering will force the roots to penetrate deeper in search of moisture.

While a one-time treatment is effective in temporarily reducing mosquito populations, monthly treatments are required to continue the extermination cycle. 

EPA and state departments (usually the State Department of Agriculture) register or license pesticides for use in the United States. EPA receives its authority to register pesticides under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). States are authorized to regulate pesticides under FIFRA and under state pesticide laws. States may place more restrictive requirements on pesticides than EPA. Pesticides must be registered both by EPA and the state before distribution. The United States has one of the most stringent pesticide regulatory systems in the world. The safety and effectiveness of each product is thoroughly evaluated by agency toxicologists to ensure products meet strict safety standards. In most cases, pesticides are subject to more testing than pharmaceutical drugs. Professional applicators are highly trained and adhere to all state regulations concerning pesticide use. The pest management products that are available to the homeowner (at any hardware, department or grocery store) for use on lawns are virtually the same products that commercial lawn care companies use. Like other products used in and around the home such as paints, cleaners, medicines and fuels, pesticides should always be used responsibly, and only when needed. When used and stored according to their directions, they present a low risk to the safety of people, pets and the environment.

Mosquitoes tend to rest on the underside of leaf surfaces, in dense plant material such as trees, shrubs, hedges, grasses & under structures like decks, porches, and stairways. 

Remove mosquito habitats. Two stages of the mosquito lifecycle require water. Eliminating sources that collect standing water such as old tires, clogged gutters, bird baths or areas where puddles are formed effectively reduces mosquito breeding grounds. 

No. After the product is applied it is broken down quickly by soil microbes and other means into harmless substances - water, carbon dioxide and humus. This occurs within a short period of time, generally less than thirty days.

The EPA regulates the use of pesticides under the authority of two federal statutes: The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and the Federal Food, Drug, and Cosmetic Act (FFDCA). EPA scientists and analysts carefully review test data to determine whether to register (license) a pesticide product or a use and whether specific restrictions are necessary.

Weed Man’s weed control products are tested, approved for use and applied by licensed, trained professionals.




When applying, we always recommend that a customer waits approximately 30 minutes until the treated areas have dried. As soon as the product has dried, you can go back to enjoying your outdoor space.

One application will be effective for approximately 30 days.

Although water is a common breeding ground for mosquitoes, it would be environmentally irresponsible to treat these areas. For this reason, we maintain a safe distance from any water sources when applying our mosquito control treatment. 

Yes, Weed Man professionals follow the preventive IPM approach. It is contemporary, responsible and ensures a healthy lawn and environment. Weed Man professionals have been using this approach for many years.

Many dog owners get frustrated by the spots their pets leave on the lawn by going to the bathroom there, but there aren't many ways to avoid this other than training your dog to only go in one particular area of the lawn. The problem is that the high quantity of salt in the animal's urine essentially burns the turf. If this problem really bothers you, veterinarians offer some medicines that reduce the amount of salt in animal's urine and will at least minimize the problem.

Mosquito treatments whether they are natural based treatments or synthetic-based treatments are evaluated for safety from the US Environmental Protection Agency. These registered compounds are safe and effective when they are prepared and applied according to their labeled use. Prior to their approval for use, scientific risk-assessments are performed by the EPA, using all available data. From such assessments, acceptable safe residue levels are established which is often six orders of magnitude—one-millionth—of levels that could be harmful. However, we do recommend that children and pets be kept inside during spraying, and for a minimum of 30 minutes after the application has been completed. 

You need to respect anything applied to your lawn. Obviously, you want to be aware of when an application is made to your lawn, and that's one reason why we post signs in your yard when we apply. You should then wait at least until the application dries before going on the grass or letting the pets out, and that can be 15 minutes or 24 hours. Be sure to ask your local Weed Man for the drying times of specific products. It's important that you know that these products have all been carefully screened and are regulated by the United States Environmental Protection Agency. On top of that, we as lawn care professionals have a broad range of products to choose from, and at Weed Man we focus on selecting the ones that are most friendly to our applicators.

Many people fear things that they know very little about. In fact, people naturally have a tendency to fear anything that is man-made, especially chemicals. However, many people do not recognize that there are things that occur in nature, including natural chemicals, that can be just as toxic as or even more harmful than man-made substances. It is important to recognize that it is the dose that makes the poison. All substances can be toxic (including water) depending on the dose.

Grass clippings should be left on the lawn when mowing. "Grass-cycling" is a natural and environmentally beneficial practice. Grass clippings are about 90 percent water by weight. Because they are high in protein they should be left on the lawn to decompose and add nutrients to the soil. Grass-cycling also reduces waste and conserves landfill space. It is only necessary to remove lawn clippings if they are long and will smother the lawn.

Although shade is a good thing, especially in the summer, it can be a significant limiting factor for lawns. Turf grass will respond to shade by leaf elongation and decreases in stand density. There may be instances where turf should not be attempted because of the low light intensity. Here are a few things you can do to help your lawn: mow a bit taller, overseed with a shade mix including grasses like creeping red fescue, keep leaf litter picked up, selectively prune dense trees to allow more filtered light to enter, and manage watering to avoid over watering and increasing disease incidence. Some types of trees, i.e. Silver Maples and Black Walnut, can be toxic to Bluegrass, making it difficult to grow Bluegrass under these trees.

Proper watering and mowing are the two biggest concerns. You need to mow at least once a week during growth periods. When mowing, sharp mower blades are extremely important. Rusty or dull blades rip the grass instead of cutting it, providing opportunities for problems, such as diseases, to infest the lawn. As for irrigation, you don't want to over water because that will set the grass up for disease problems as well. At the same time, underwatering stresses the turf and creates opportunities for weeds to grow. Be sure that your sprinkler system covers the lawn well and irrigates deeply to encourage deep root growth and makes the turf less susceptible to drought. Lastly, as your landscape develops, keep an eye on trees and shrubs and make sure they remain properly pruned or thinned to allow sufficient light to reach the lawn.

The experts at the Environmental Protection Agency extensively evaluate all pest control products. 2,4-D, the product that is commonly used for weed control is among the most highly tested products in the world. The product has been used on lawns, golf courses, parks and other turf areas for thirty years. When applied by trained technicians and according to label directions, it provides effective control of broadleaf weeds without posing an unreasonable risk to humans, pets or the environment. At least twelve independent scientific panels have reviewed both the toxicology and epidemiology data packages of 2,4-D in the last ten years. All have concluded that no cause and effect relationship has been established between 2,4-D and cancer and/or that the continued use of 2,4-D poses no unreasonable risk to man or the environment. Copies of the reports can be seen on the internet www.24d.org. Consequently, 2,4-D has been the most researched herbicide on earth with thousands of studies having been performed on it in the last 50 years. Before a pest control product is applied to a turf area it is diluted according to product label directions. For example, commonly used weed control products are most often highly diluted with water before being applied by a professional applicator.

Please follow your Weed Man professional's written instructions and remain off a treated lawn until it has dried – or, as an extra precaution, for 24 hours. This will reduce the potential for contact with the material to practically nothing. When the material is applied to a lawn, it dries very quickly to the target area. Once the product has dried on the surface of plants, it becomes practically impossible to remove any residues from the surfaces.

Your lawn should be mowed regularly at a proper height. This means that your lawn may require mowing more than once a week during peak growth and only once every two weeks during periods of slow growth. Since the root system of a grass plant grows proportionately to the above ground parts of the plant, a longer cutting height results in a stronger, deeper root system.

One big reason is that you're hiring an expert who can diagnose problems. We can tell you whether or not the problem with your lawn is a disease, an insect or simply a lack of water, and that can be challenging for you, the homeowner, to do alone. In addition, when you hire Weed Man, you're buying a guarantee for results, and that's not always the case when you're buying products right off the shelf. We can offer our customers this type of commitment because we know we're applying the right amount of the right products at the right time, and do-it-yourselfers can't be sure of that. We'll keep coming out until the lawn meets your satisfaction. Plus, putting down the right product at the right rate and at the right time is especially important for many lawn problems, including crabgrass, and in some areas of the country, you may have to apply an herbicide twice to get control. We'll make sure that happens.

Unfortunately, lawn care is not like switching on a light and having the grass stay green all year. Just like people, lawns need continual feeding. There are fertilizers that feed over longer periods of time, but we're accomplishing other things as well with our visits. For example, we want to see if there are any dry spots or weed problems that need to be kept in check. In addition, some weeds appear in the spring while other weeds show up in the fall, and we need to control them all.

Mowing properly is essential for maintaining a quality turf throughout the long haul. This includes not only the optimum height but also regular frequency with a sharp blade to ensure both a clean cut and minimizing the chance to shock the grass by taking off too much at a time. Removal of no more than 1/3 of the leaf blade at one time ensures this. To get back to the question, a lawn that is mowed below optimal heights will see reduced vigor as a result of its decreased ability to manufacture food. Lower mowing heights also diminish the root system, thus reducing its ability to take up water and nutrients. Proper height and mowing frequency will result in a denser and healthier turf that is more likely to withstand stresses coming from disease, heat, traffic, and weed infestation.

We have specific tasks we are doing on each visit. Our equipment is calibrated to provide the proper rate, our vehicle is fully loaded for our day’s work, and we are well-organized, resulting in an efficient use of our time. We will be many more times efficient than the average homeowner because of the above as well as the fact that we do this every day. When we are out on the lawn, we inspect the turf for potentially damaging insects, weeds, or diseases. We also note your cultural practices and leave information for your review. In addition to the inspections completed upon each visit, depending on location, a free mid-summer inspection is completed with a written report left for review by the homeowner. The value you are receiving is in the good results and information. Satisfaction guaranteed – and, hopefully, through good communication up front, a realistic expectation of the results has been presented to you.
