Die, parasite !!!

I had bought the spray because my tomcat had just dragged the last few weeks daily ticks into the home. His collar causes namely that half-eaten creatures bless the temporal and I catch him once a day for combing and searching, but until then they scurry merrily in coat and (much to my chagrin) around in my apartment.

My hangover the agent does not belong naturally.

But I have fogged my balcony including door and window frames. The plan behind this was to create a small "inhibitions" that destroyed the cattle stuff before my cat can wear them in the house (it passes over a tree on the balcony and then to the apartment).

This morning came to the spray, this morning was fogged and early evening I have a relatively large spider (elid them tuts me) and two dead ticks collected from the balcony. In addition, relatively quickly after spraying were two small black Käter dead in my apartment.

This shows me the one hand that the medication works and that it was necessary, because actually tick up basked far away from me or my fur ball on my balcony!

I hope now only that the agent remains effective and not yet affected or my pet at some point loses effectiveness as it can happen in chemical lobes sometimes.
Do you have experience in the last two points? What do I have to hire me?
