We have ants and last night I saw 4 small cockroaches in the Cocina. My Dom friends said buy some Baygon. Anyone tried that here. Even with the cocina sparkling clean we still have ants. The cockroaches are definitely new never had those here before.
You really need to stop bringing in barrio rats to your villa.
What he said, the chalk does work.
Use Fipronil
Safe for humans and animals. Extremely effective - exterminates colonies of ants, termites, cocroaches. I even tried it against wood worms in my caoba kitchen furniture - works great.
Buy on Amazon and have it shipped here. Read also reviews.
I use boric acid. It is available at La serina in the bulk area. No smell, cheap and safe.
I'm pretty sure that Matilda posted that Fipronil liquid is available in bottles at agro-vererinarios, she buys it for her dogs [works like Frontline for fleas and ticks].
How do you use it for other insects? Interesting.
Does it have a brand name? Couldn't fin it at La Sirena in Bavaro...
