The reason why fipronil is not the solution is in the dosage of its use in pets.
-Two days before and after I could not wash your pet, the reason is so that the poison can act. If the water washes away your pet's product, the dilution of the workers in the nest by sharing the product reduces its effectiveness, which as the first ones succumb reduces the quantity and this will mean that it will not reach the entire nest.
- The treatment should be repeated every 4 or 5 weeks depending on the weight and size of your pet. This means that there will be a period of inactivity for that nest in your apiary, but if you have 3 nests in your area it is evident that it will be a palliative measure and not a definitive one.
If one reviews the data from New Zealand, Argentina and Chile to combat vespa germanica with fipronil bait, one will also realize that they have not eradicated their "invasive exotic species."
I understand their position at that time but with more than 15 years of experience facing "invasive exotic species" it is clear that today it is not an acceptable solution and even less so if it is also ILLEGAL.
