Re: [PestList] Suggestion regarding pest treatment in an art gallery stationed in Mumbai, India

[David Loughlin]

Hello Rahul Rentokil PCI are probably the largest pest control service company in India but perhaps not the brightest.  They seem to be wanting to throw everything including the kitchen sink at your cockroach problem. If they are proposing to use gels, that is great and fipronil based gel is a decent one to use. However for gels to work, it is advised not to disturb the population by applying any other insecticide, so why they would want to use a repellent and a insecticidal sprays is confusing unless they are treating different parts of your gallery, but even then I wouldn’t. Gels are placed discretely so the cockroaches feed on them, then go back to their harbourages to die. Sprays would disturb this effect. Clothianidin Is a more modern chemical, an neonicotinoid and also used in gel baits but the SDS you supplied is for WDG or water dispersable granules which suggests they want to spray it.  Again I would not recommend this alongside gels. It has a broad spectrum effect so will take care of most crawling insects. I wouldn’t allow propoxur anywhere near the gallery.  Already banned in many countries, carbamates are old technology and as acetylcholinesterase inhibitors, not great for us.  Gumtree are a good Indian company making some decent insect traps so those are fine and I would want to see PCI monitoring the situation.  PCI also have access to super sized traps from Gumtree like the Exoroach so that might be worth exploring with them. Hope this helps.  Good luck.
