How long does it take after an exterminator performs a service for cockroaches to die completely? It's normal to see a few cockroaches weeks after treatment, regardless of how well the treatment works. Some cockroaches survive pesticide spraying for a few more days after spraying. There are a number of factors that affect how long it takes cockroaches to die after treatment. The cockroach species involved makes all the difference.
For example, it may take up to five weeks to completely eliminate your property from German cockroaches after treatment. However, during the first week alone, their number should be reduced by 70% to 80%. The extent of the infestation also makes a difference. A serious infestation may take longer to completely eradicate and may even require several treatments to fully resolve.
For example, in the case of rodents or cockroaches, the results will take a little longer, from one or two days to two weeks. A cockroach pest control technician could get rid of a small infestation in a week or two. In more serious cases, such as an infestation of resistant German cockroaches, bait and insecticides can take months to work throughout the colony and eliminate the problem completely. With the highest quality pest control treatments, you're likely to see a reduction in cockroach activity in a matter of days, while total control and complete elimination of infestation can take months.
To control cockroaches, you should call a professional pest control team in your local area and they can give your home an insulated heat treatment or other treatments to eliminate cockroaches from your home. The fastest and most effective methods of pest control are those administered by professionals trained in pest control. Regardless of the pest control product, be sure to talk to your pest control technician about best practices and safety measures.
