Early Summer Pest Problems

Summer is fast approaching the Orange and LA County areas, and the weather is still very nice; warm days and cool nights. Before the heat arrives the bugs are ramping up their initial foraging and they are starting to emerge in force. It is a lovely time of year for us; unfortunately the Ants love it too. This is why you’ve hired PacWest Exterminators to protect your home this year.


Argentine Ant Control

The Spring Foundational treatments have been done on your home and now it’s time for the primary Summer Ant Protective treatment. Argentine Ants are the biggest nuisance ant pests in Orange and Los Angeles Counties. The Very Large Colony of Argentine Ants extends from Northern California down through the Mexican/US border. This Massive colony has eliminated most other ant species in the area and infests homes regularly.


Termidor Treatments

To combat these infestations, PacWest Exterminators utilizes Termidor from BASF. This breakthrough chemical has revolutionized Ant control through its ability to spread through a colony via the ant’s natural social behavior. As ants pass through the areas treated with Termidor they pick up fipronil, the active ingredient, on their bodies. This chemical is not lethal for 48-72 hours and during that delay the chemical transfers to other ants via touch (cleaning each other, feeding each other, and communicating with each other.) This ability to spread to ants that never came into physical contact with the treated area allows this amazing chemical to eliminate large numbers of ants quickly. Also, since this chemical is not detectable to ants they cannot avoid it or protect themselves from its effects.


Due to the nature of this chemical we want to ask all of our customers to completely avoid using any over-the-counter pesticides. Termidor is very sensitive to other insecticides and if any other pesticides are sprayed in the area Termidor is used then Termidor will not work and the ants will not be eliminated. We want to remind you, if you are under a service contract with us and are having a problem with covered insects inside your home then please call us so we can come and treat the problem for you. The other reason we want to ensure your Termidor treatment is maximally effective is because of our limited ability to use this chemical. Termidor is limited to only two uses on your property per year. This is because it is one of the most popular active ingredients in the world and is used extensively in agricultural and in over-the-counter flea treatments. If you partner with PacWest Exterminators then we can completely control your ant problem all summer long. You will never have to worry about waking up to that dreaded invasion in your kitchen or bathroom again!
