Brown recluse spiders in Florida are known to be active from March to October. A shy, furtive nature is the hallmark of the brown recluse. Florida residents might have a brown recluse spider in their homes now- and never even know!

They get into homes by climbing onto furniture when they are being moved and catching rides. It is also easy for brown recluse spiders to stay hidden because they do not eat a lot. They can go for up to ten months without food or water. When they feed, they prefer to go for already-dead insects. This is not because they aren’t capable hunters. These spiders move really fast and have great eyesight. They also have extremely venomous bites.

Female brown recluse spiders lay eggs from May to July. They are known to lay an average of 50 eggs at a go. Each egg is wrapped in a silk sac that is off-white.
