"The inspection was scheduled promptly, the inspector did a careful and thorough job. He provided a somewhat dire assessment on the ant issues (I knew that we had a problem), provided a full suite of things which the company could tend to to extend the life of the interior wood structure and exclude pests for the longer term. Their use of all natural chemical control was a big plus. We signed a contract and the technician came a few days later. Unfortunately, the birds were "in" on that cool and rainy day so we decided to leave them to his second visit to complete the treatments/exclusion. The technician was polite, tidy, and willing to answer questions. On the second treatment day, the birds were out and the exclusion process was completed. They guarantee the work done for a year with the promise of return to address any issues. It is too early to assess the longer term run at this point but so far, so good."

Pest Control FAQs, answered by experts

The time and number of treatments required for an exterminator to get rid of roaches depend on factors like the roach type, infestation severity, and extermination method. For small infestations, a single treatment may be sufficient, showing results within 1 to 3 days. However, most cases require several treatments and take about 2 to 8 weeks to resolve completely. Severe infestations can take up to 6 months to fully eliminate.

In general, mouse droppings can remain infectious for 2 to 3 days at room temperature. Through their urine and feces, rodents can spread harmful diseases to humans. Common infectious diseases include hantavirus, salmonellosis, leptospirosis, and LCM.

However, depending on the specific virus and environmental conditions, mouse droppings can carry viruses for shorter or longer periods of time. For example, Salmonella can survive in mouse droppings several days and even weeks.

Mosquito fogging should be done every two days during the first week of treatment. This level of frequency helps to interrupt the mosquito breeding cycle and prevent them from laying eggs in your yard. After the first week, mosquito fogging can be reduced to a schedule of once a week.

Whether a one-time spray treatment to control mosquitoes is enough depends on multiple factors. Often, you’ll notice a big difference after one application. However, mosquitoes are likely to return if you don't reduce attractive standing water habitats. This usually takes four to eight weeks if it’s still prime mosquito season.

To keep animals out, you must prevent them from entering. As long as they can get in, the problem will persist. That said, consider making your attic less inviting using deterrents like motion-activated lights or ultrasonic devices. Additionally, keeping a well-maintained, clean, and uncluttered attic that you regularly inspect for activity may make the space less attractive to critters.
