Flies Bite Pets. What Can You Do About It?

Yes, you read that right: flies, the kind that people find endlessly irritating, are also vicious pests. Commonly found near livestock or waterways, black flies (or buffalo gnats) attack their prey’s skin repeatedly. While they don’t spread disease like other parasites, they can trigger a full-blown allergic response in pets. As they are ubiquitous in the warm, humid months, flies bite pets with greater frequency in spring and summer. Luckily, there are ways to combat their terrible effect on animals.
