Which brownrecluse spider spray is the best? We get asked that question a lot. There really isn’t any one spray that’s best. In fact, it’s a combination of “tools”. The tools include some sprays but the real key is where you apply them. Even the best products won’t help much if they’re not applied where it matters most. Since each infestation is unique to itself, it’s important to survey and understand the problem at hand. Inside infestations will need some Baygon and Lamda-Cyhalothrin. Be sure to set up some traps in rooms where activity is either seen or suspected to be active. More specific details are explained in our spider article here.
