Tekko Pro Insect Growth Regulator Concentrate is a product that makes controlling the pest population on your property simple. This product uses its two active ingredients: pyriproxyfen and novaluron, to stop the juvenile pests from growing into adults. From disrupting the life cycle of the listed pests to keeping the juveniles from growing into adults, this product gives you a long term solution to pest control problems on your property. For use in many areas, from furniture and carpets to kernels and poultry houses. Tekko Pro Insect Growth Regulator Concentrate is a great example of using pesticides to deal with pests over a longer period of time than other products that kill the pests outright, but can't control the population from rebounding. The active ingredients are the key behind behind the product's success, for two completely different reasons. Pripoxyfen is a juvenile hormone analog, which makes the pre-adult stage of the insect longer so that it dies before it can reproduce. And novaluron is a Chitin Sythesis Inhibitor, stops the insect from being able to molt, making it more likely to die from outside influences. As you can see, these two chemicals work together to stop your pest control problems in their tracks. Tekko Pro Insect Growth Regulator Concentrate works for up to 7 months after application.
