How to Control American Roaches / Palmetto Bugs
American Roaches come from the outside of the home, so it is best to spray a liquid insecticide around the outside foundation of the home such as Talstar One or Cynoff WP, rather than using roach baits. Also focus on sealing up cracks around doors and in the foundation so roaches can't get in.
Talstar would be a good choice to use around the inside and outside of your home to eliminate centipedes. Indoors you can apply Talstar P to door frames, window frames, places where utilities enter into the structure, and any other place where the insects can gain entry. Outdoors you should apply the product to door frames, window frames, places where utilities enter into the structure, around the bottom of the foundation and out onto the ground directly around the foundation. You can also limit favorable conditions that the centipedes need to thrive.
Remove Favorabe Conditions
Talstar is meant to be applied to cracks and crevices not as a broadcast to floors. If you do mop an area that Talstar has been applied, then you could potentially take the product up and Talstar would need to be re applied.
A hand pump sprayer or backpack sprayer would be the preferred method of application for using Talstar P, a sponge would be not recommended. When treating around doors and windows you will want to spray around the frame of the windows themselves and where the windows slide past each other when opening You would not need to spray the glass to get an effective treatment but can spray screens if needed.
First be sure to protect your biggest investment, your home. Put up a barrier using Termidor SC. Please see our article on Barrier Treatments. For the tree, you can inject Dominion 2L.
Talstar P does work for boxelder bugs. Talstar P does not have an immediate knockdown effect but it does leave a long lasting residual. We do encourage our customers to apply Talstar P once a month through the stinkbug/boxelder bug season (August-November).
We would not recommend applying a product on top of the treated areas with Talstar P. It offers a residual control and takes time for eradication. Raid is more of a contact spray. We recommend that you take a few moments to read our article on eliminating roaches for more helpful tips. We also carry professional Roach Control Kits are effective in treating this insect.
The general rule of thumb for insecticide concentrates such as Talstar P is that they are good for about 3-5 years from the date of purchase as long as they have been stored at room temperature. If your Talstar is six years old, it certainly would not hurt anything if you wanted to try to use it, but if you find that it is not working as well as it used to, it may be time for some new product. You may also want to speak with the manufacturer directly to see what they would recommend. You can reach FMC at 800-321-1362.
