I am getting an infestation of house crickets in the kitchen despite not having any food out. I went outside and found them huddled around the perimeter of one corner of the house and also climbing the walls. I used ortho home defense which kills them (with a hefty dose) but they were back the next night (despite the 12-month protection promise on the bottle). I tried the same thing with EcoLogic Ant and Roach killer but they were also back the next night (despite the use of lemongrass oil in the formula which I read repels crickets). Last year I tried terro ant killer but it also was not effective. All 3 products have crickets listed. Can anyone recommend a product I can use around the house's perimeter to repel crickets from coming here?
