Early Fall Pest Problems in Orange & LA Counties

Summer is starting to wind down, but here in California you’d never know it in August and September. These tend to be our two hottest months and that means bugs, or more specifically Argentine Ants. In these last two months of summer heat the local Ant colonies have reached their zenith. All of the eggs laid in spring have hatched and reached maturity. These young ants have joined the already large workforce which now needs to create jobs by invading your home! The colony is now making its biggest push of the year to collect supplies for winter. The ants are out in the neighborhood in full force, especially in the cool of the morning and the early evening. This big end of summer push is what your Pest Control Service Contract is designed to protect you against.
Fall Treatment Methods

PacWest Exterminators early fall treatments is our second, and final, use of our specialized ant chemical this year. We time this final treatment with the time of the year it will be most effective at giving you long lasting protection. BY attacking the colony during its big push for winter food we both interrupt that process and catch a large number of ants foraging on the surface. This allows us to maximize both our kill, by affecting large numbers of ants, and our effectiveness, by reducing their ability to store up for winter and thereby thrive next year. This timing is also vitally important since we are only allowed to use this pesticide twice a year. With this limitation in mind we have designed your service to be the most effective possible.
