Plain-English summary
A group of 24 beagle dogs was tested to see how well different spot-on treatments could prevent mosquitoes from feeding on them. The dogs were divided into four groups, with some receiving treatments containing fipronil-(S)-methoprene, metaflumizone combined with amitraz, or pyriprole, while others were left untreated. After testing, the fipronil-(S)-methoprene treatment significantly reduced the number of mosquitoes that fed on the dogs and resulted in more dead mosquitoes. However, the overall effectiveness of these treatments was not strong enough to recommend them for preventing heartworm disease (dirofilariosis).

Abstract
A controlled clinical trial was carried out to assess the effectiveness of pyriprole, metaflumizone combined with amitraz, and fipronil-(S)-methoprene commercial spot-on products in preventing adult female Culex pipiens pipiens from feeding on dogs. Twenty-four beagle dogs were tested for their attractiveness to the mosquitoes and ranked accordingly to produce four groups of equivalent sensitivity to mosquitoes; six were treated with the pyriprole spot-on, six with the metaflumizone combined with amitraz spot-on, six with the fipronil-(S)-methoprene spot-on, and six were left untreated. All the dogs were challenged with 50 unfed adult female Culex in cages for one hour seven days before the treatment, and one and seven days after it. The mosquitoes were checked for blood feeding after one hour and for mortality 24 hours after they had been released into the cages. There was a significant reduction in the number of engorged mosquitoes only with the fipronil-(S)-methoprene product and there were significantly more dead mosquitoes with this product and the pyriprole product, but their effects were too small for them to be recommended for use in a dirofilariosis prevention programme.
